BBC reporting the coming of a stormy Sunday/Monday with pressure down to approx 940mb. Expect storm force winds and severe turbulence, so the lady said.
Just checked my roster and see I land late Sunday.
Get your videos cameras ready to record all the wing tip taps, gross-wind landings, wheel squirming bounces, crab kicking and ring squeezing landings so that we can read all about how bad/rubbish/badly trained/inexperienced/unsafe/loco-hence untrained we all are on Tuesday.
Does news of a rumour qualify for this thread?

Press Association says (http://ukpress.google.com/article/ALeqM5hefZiPXNjdmzYdIAh9aeC1xigxzg) 80mph winds are expected. It has to cross Ireland to get to the UK, of course, and ie expected to be pretty severe. Considering some of the Dublin landings I've experienced as SLF, I'm glad I'm not travelling during this period. :ouch:

I remember flying a helicopter out to an oil rig in the North Sea in the 80's altimeters those days only went to 945mb but the pressure went down below 940mb so the decision was made to all fly on 950mb for separation purposes.
I do remember it was a good bumpy ride, have fun!

Looking at the surface weather charts (Friday to Monday as I type), it is interesting to see that the low in question does not even form until Sunday 1200.

For a short time on Friday the BBC web site's weather page was showing it as low as 936mb. The latest forecast is 948mb.

To put this in perspective, the great storm of 1987 that hit England with gusts of up to 100kts was 958mb.

"Gross-wind landings"??? Not sure this would be welcome in the cockpit!

:-)

On one of my first x-wind landings (not quite 55kts and gusting but enough for
an inexperienced E145 F/O) I was very proud and happy that my captain allowed/gave me the chance to land the thing. OK, so it wasn't the best - I was more than a little nervous and the approach wasn't as smooth as it could have been. At one point I make a slight overcorrection and at that point said captain farted - long, loud and the unmistakable smell of fear.

Nothing more was said until we parked at the gate when captain apologies; C/C came in to cockpit and remarked that after that approach the cabin smelt the same too...

Oh 'ing great - I'm supposed to be flying from BHX-DUS on Monday....:hmm:

However, the Met Office is rather good at being somewhat alarmist these elf 'n safety, ambulance-chasing lawyer days, ever since it totally porked up forecasting The Great Storm, so I am taking this forecast with a pinch of salt right now.

I doubt whether the gushing weather-wenches on TV can provide anything more accurate before Monday.

I doubt whether the gushing weather-wenches on TV can provide anything more accurate before Monday.

Looking at the surface pressure forecast sequence, I'd say they'll have a reasonable idea on Sunday when the particular area of low pressure that's supposed to cause the problem is predicted to form.

They'll have a reasonable idea - they have their model with all its chaos theory and the sim gets run repeatedly with slightly different initial conditions. If they all tend to converge on the same answer then they'll claim it as the forecast, if the sims all diverge then they usually just declare the weather as unsettled without predicting anything.

By Wednesday we'll have the answer.

You tend to get more snow when the atmosphere is on average _warmer_, not colder. Warmer air can support more absolute moisture, and then when the air cools even slightly the moisture falls out massively as snow.

I'm right next door to Ottawa and it's pretty severe here. We had 25cm Wednesday as well. Most of my spare time is spent shifting snow about. :*

All this huffing and puffing from the met office with severe weather warnings covering the whole of England, yet when you look at their forecast for Monday for Heathrow for example the wind speed is given as 34MPH which is less than gale force. The only serious winds would appear to be likely in Devon and Cornwall. up to 61 MPH which is force 10, and Wales up to 45MPH, force 8 Higher in gusts of course.

Who recons the following will happen?

(a) the low pressure will deepen but drift north of UK with no effect on mainland or
(b) the low pressure won't deepen?

I'm very impressed if they get it right. Any weather experts out there who can shed any light on how they are predicting this. I know computer models are predicting this, but surely you have to feed in information in order for output to be 940mb depression?

In my list of possible events for the expected Low Pressure, I chose 'gross wind' as it seems to fit nicely.
I had thought I was on standby on Monday but now I see I have an early start, four leg rotation. I guess someone reading this thread did the sensible thing and called in sick for Monday! I wonder who I can blame for that?
My camcorder is fully charged. I only hope that I don't end up the subject of the next one minute judder on You Tube. Having said that, some of those one minute judders on some other sites can be quite entertaining!
I suspect that, like other events in the past, this might well amount to nothing more than a storm in a tea-cup. Most of the disastrous events in recent years have not been predicted and many of the forecast events have turned out to be a damp squib.
I will keep my fingers crossed for the latter and quiet landings on Monday.

Did some circuits in a Cessna 150 once at Longside where the QNH was around 945, off my altimeter scale. Twas flat calm so I reckon I was close to the 'X' shown on the synoptic charts. And some time later I had a bimble around the same morning as the English 'hurricane' but I was in a Cessna 172 by then, could handle it better than a 150!

Good luck to you lot who do it for a living and hope that 'X' coincides with localiser established.

Is 940mb 'extreme' or is that how it has been quoted by the hysterical media?

Going from all the forecasts, and adding some smart-arse comment I would say SW Ireland is going to get quite a battering, along with Irish Sea and SW England (F10 - F11) Sunday night - Monday morning. So far as mainland England goes in particular, F8 for a time between 0600 - 0900 Monday is most likely the highest number and from the South. After 0900, winds turning West, South West and dropping F5 - F6... The future may prove me wrong of course, but why not throw in some sensible numbers to mull over before the 'extreme' breeze ruffles the wingtips?

I'm flying LHR - NRT on Monday so here's hoping these numbers get to the right 'person' , 'persons' or 'things' who have a say in such matters :ok:

9th Mar 2008, 09:30
Apologies for the SLF question - understandably most of the comments on this thread relate to landings but what is the impact of cross winds on take offs?

XCweather is showing 30mph from the south east at NCL for 06.00 tomorrow morning, so straight across the runway.

Is this likely to have an impact on departures at this peak time?

9th Mar 2008, 10:19
gusting 38kts fis max x w/c for a 320 so you'll be fine.....737 should be ok too. ISObars not as tightly packed as forecast.....it'll be sporty all right but very doo-able.:ok:

BEagle
9th Mar 2008, 10:27
SWBKCB, basically the problem on take-off is that the aeroplane will try to weathercock into wind before it is travelling fast enough for the rudder to be effective - so the pilot will need to rely upon nosewheel steering early in the take-off roll - and that has limited authority as speed increases. The skill comes in transferring smoothly from nosewheel steering to rudder during the take-off roll.

For that reason, I always chose a full power take-off in strong crosswinds to minimise the time on the runway.

Another problem is that the into-wind wing will try to lift in a strong cross-wind; this can be worse in swept wing aeroplanes if the pilot needs to use a lot of rudder quickly in the downwind direction to counteract an unexpected gust causing weathercocking. So in conventional aircraft, a significant amount of into-wind control column deflexion is also needed, which will change as the aircraft acclerates.

All-in-all, there will be a fair bit of fancy footwork and skilled coordination going on during a crosswind take-off! Then, when the aeroplane becomes airborne, the pilot has to turn the aircaft into wind to maintain the required track as well as coping with turbulence before the autopilot can be safely engaged. Perhaps more of a challenge in conventional aircraft than in 'fly-by-wire' Airbus aircraft whose flight control computers assist the pilot extremely well as soon as the aircraft becomes airborne and the 'control law' blends from 'ground' to 'normal' flight in the first 5 seconds of flight.

However, the crosswind limit takes into account handling by an 'average' pilot - so you can rest assured that if the wind is less than the limit, conditions will be more demanding than on calm days, but not impossibly so.

I note that there are already differing opinions on various met websites regarding the threat posed by tomorrow's weather - fingers crossed that the lurid picture being painted by the BBC will turn out to be somewhat exaggerated!

Well it will hit us tonight here on the western coast of Ireland. So I will give you breathless minute by minute reports of the drama and destruction. I'm looking forward to heading down to a point overlooking Galway bay at high tide. It is always a spectacle. It's an even better spectacle from inside a coffee shop on the prom.

It's a beautiful day here so far, mild and sunny, despite all the showers showing up on radar. We are just getting sprinkled occasionally.

The calm before the storm:)

I do think the British met office and the BBC weather people are overplaying it a bit. The old 'Don't worry there won't be a hurricane' comment is ingrained in the folk memory of the forecasters. So they make sure to build it up every time something more than a zephyr stirs the leaves on the trees.

In contrast the Irish met office are practically laid back about it. This is their latest:

Today
Most of the showers today will be over the western half of the country, with hail, thunder and sleet mixed in. Otherwise the day will be bright and fairly sunny, but rather cold and breezy with highest temperatuers of 7 to 9C.

Tonight
Becoming very wet and very windy this evening and tonight. Lowest temperatures of 4 to 7C.

Tomorrow
Further outbreaks of heavy rain tomorrow and still very windy.

That's it???? Becoming very wet and very windy? It's always like that round here.

What you have to remember here is that since the farse of 87 the british media and met office have always over-played any weather situation that is out of the norm, beit fog, snow, wind or rain.

The way they get away with this is that they tell joe public to batten down the hatches as on this occasion damaging winds will hit the U.K. When these damaging gusts hit and basically rattle a few crisp packets on the floor everydoby gives a big sigh of relief that nobody gets hurt and travel caos is kept to a minimum.

meanwhile anybody in the Industry has already looked at the tafs and realised how much of a over ramp this is...for example......

EGCC 091018Z 091818 21010KT 9999 FEW025 BECMG 2124 18020G30KT
BECMG 0003 15032G45KT TEMPO 0207 4000 RA BKN010 BECMG 0709

BECMG 1417 30015G25KT=

so gusting 45 kts for a 7 ish hour period......aint that bad...but saying that, it is across the runway and with rain forecast...might be interesting with the effect of olympic house at EGCC......but still nowhere near as bad as the hurricane like winds that the BBC are saying will relocate me from Manchester to Hull overnight !!!

PKPF68-77 The problem is that every time we get a severe weather warning and all we get is a few gusts that do little harm the more likely we are to then start to ignore them as being the usual over the top hype so that when they really do mean it we all don't take any notice of it.
As I see the situation at the moment, it's the western part of the UK that is going to get strong winds, the Eastern side is just going to be a normal windy winters day.

In fact Wed appears to be worse for the East than Monday does.

Breaking News: West coast of Ireland: Check the current radar image as of 20:39 Sunday Very impressive, lots of pink in it. I haven't seen a radar image that impressive for a while.

I ventured out to check out current conditions, well to get a bottle of wine and a Chinese. I felt like Captain Scott or should it be Shackleton, after all he came back. Wind is getting up now, pretty gusty, estimate gusting thirty knots or so.

Just listened in on EINN, they are reporting 150/36 gusting 45 as at 22:08.

They appear to be diverting people to Cork because of the crosswind. and were estimating a 2 hour delay before the wind backs sufficiently.

Well it's started already.

EINN on liveatc is worth a listen at the moment

Several Ryanair flights holding at Clonmel for the last 30 minutes or so. Two more on the way behind as well.

Shannon weather is giving max gust of 48 knots currently, straight across the runway. Cork is even windier but straight down Runway 17.

Miserable conditions, I don't envy anyone out flying this evening.


My guess is we'll see a few Dublin diversions pretty soon.

corsair
9th Mar 2008, 22:24
Yes, Dublin was only reporting 180 17 knots and they have the use of runway 16. Even if it gets worse in Dublin at least it will be in line with the runway.

The current radar image shows that most of Ireland is under the rain now except the extreme east coast.

The next time anyone slags off airline pilots as mere 'glorified bus drivers'. Remind them of nights like this. A lifetimes salary is earned when the weather is sporty.

At 2am today, the wind speed in Milford Haven, Pembrokeshire, hit 68mph.
Last night Gordon Brown held a crisis telephone meeting with officials from the EA, the Met Office and relevant government departments, as well as the emergency services and armed forces, to discuss the storm.
A Downing Street spokesman said: "They got the latest updates from the Met Office and Environment Agency and looked at the planned response to the incoming weather, the potential effect on the critical national infrastructure, and the contingencies in place to deal with the effects of the storm.
"They also discussed the public information campaign which is under way.
"The Prime Minister listened in on the call and made a couple of points."
Meanwhile, air and train delays and cancellations are expected.
British Airways cancelled several short-haul and domestic flights out of Heathrow Airport last night, and both Heathrow and Gatwick advised travellers to check with airlines before leaving home.

Hi all,

SLF here but just a quick question. Looking at the Met Office it shows the Northwest of England to have a 20% risk. At the moment, out of the majour airports in the UK, Liverpool and Manchester have the lowest QNHs (967mb and 970mb) - Does that mean the weather may have come more North than expected or is it normal for this to happen in majour storms?

QNH at Shannon is now 955mb :yuk:

The wind has now veered and/or abated for the time being. In the absence of much information, I wonder how many diversions there have been so far...

The decision to close Heathrow Rwy 23, to enable expansion of parking stands at T4, was no doubt caused by the planning delays to T5. :{
But it looks questionable on days like this morning. There have been no north-south runways in the South of England since Thorney Island closed many years ago. But at least we had the south-westerly ones at Heathrow and Stansted. Now we only have the Stansted one.
[EGHI (Eastleigh) operators must forgive me, but I can't see a jumbo diverting your way.]

Gatwick Rwy 26 can be a nightmare in strong south-to-SW wind, because of the turbulence/windsheer in the lee of the south-side hangars. I should know - having once performed a go-around from 50ft in a DC10-30 after a flight across the pond. We went to Stansted that day, which caused chaos. [The W/V there was 230/50, but nice and steady.]

So, would Rwy 23 at LHR actually have helped this morning, with a reported W/V of 180/25-39 (at 0815z)?
On the face of it, 50 degrees off makes the 39-knot gust into a crosswind-component of about 30 knots. This is sporting, but easier than 39 knots on Rwy 27L/R.
The 170/25-35 reported at 0615z equates to a gust-component of 30 knots on Rwy 23; 35 knots on Rwy27L/R.

Not much difference, perhaps? Ah, you have forgotten that the wind usually veers at least 10 - 20 degrees in a big gust (Northern Hemisphere). As PKPF68-77 has pointed out on another thread (?), Met observers seem to be omitting these direction-changes from the METARS, except when the change is about 30 degrees (?). But even 10 degrees makes a big difference in a 40-knot gust.

The forecast suggests that the problems in the South-East may not yet be over...
You Schiphol-based pilots always had a better chance of getting home - on days like this - than the rest of us.

Can't give you a definitive answer, I'm afraid. My understanding has been that all the London-area TAFs are done by a Heathrow-based Forecaster, who also issues Trend (2-hour) forecasts as suffixes to the LHR METARs only.

My own comment was aimed at the ACTUAL W/Vs; not the TREND W/Vs.

Is the fact that they have reported the direction variability, at last, just a coincidence?

Or has our distinguished ex-aerodrome-forecaster forumite got even more influence, with the "powers that be", than we suspected? ;)

I work in Lingfield, Surrey - directly under the approach for runway 26 at LGW. Was horrid this morning on the way into work (5 fallen trees between Tunbridge Wells and here) then cleared and is now back to windy wet weather. Went out and got my lunch earlier and watched a couple of planes on approach, thinking they're earning their crust today! One a/c was already gear down as it was over here; normally they aren't from what I've observed before.

Looking forward to your list of definitions/protocols... :rolleyes:

Great video of the LCY approach. Certainly brings back a few memories of operating in and out of there. Not sure why the Beeb is showing the clip as "Plane blown around in storms" as it seems a nicely flown stable approach and landing.

Oh god, this is the BBC Helicopter, i.e. we contracted for hundreds of hours of flying time per year and we don't know what to do with it so send it anywhere. It is called the "Graham Norton" contract - sign up for something, pay zillions, then realise you don't know what to do with them/it.

There is a relationship between windiness and the pressure reading, but very low pressure does not guarantee very strong winds - the ultimate example being the calm in the eye of a hurricane.
Indeed - the "eye" of this was over Ireland this morning, and it was quite nice outside in Dublin: sunshine, light breeze, until roughly 2PM local. The cloud is back now, and is going to get worse, but the worst winds will miss Dublin, says the forecast. It's very different in the southwest, with Shannon not a nice place to be at the moment:

Mike Smiths mob (him from Multi coloured Swap Shop)

He has the BBC contract for chopper news flying using an R44 and they have to justify the expense of the contract.

Hence lots of aerial shots in the 6/9 news:hmm:

I'm sure they would have been looking for someone to mess up an approach.
Well done to all.

Was on nights, LHR tower last night.

Tower swaying pretty constantly from 0300.

Between 0600 - 0700 about 2 in 5 approaches threw it away and buggered off to SS, Brussels, Amsterdam etc.

Wind was a constant 180@25 gusting 40.:eek:

Some interesting landings, but even more entertaining go arounds, watching the heavies try to turn left onto 150 with the stonking southerly wind

I wonder if it is any coincidence that as I was reading this thread, an advert for Storm Aviation popped up? :}

In Manchester still quite calm in the centre of the low with a QNH of 959 - just starting to go up from the low of 958. But the forecast is for 300/22G38kt later from 2100 so approaches will be difficult again (with turbulence from Olympic House /T1) after this morning's crosswind 140/24G39kt. :{

Here's to a safe evening

Got into EGSS today, crosswind on limits for landing, and over for t\o so had to hang around for an hour and a half waiting for it to calm down. RWY 23 in use and wind was 170 29G45.

Definetly got the adrenalin going, good thing it was the captains leg!

Think the pressure was 972 when we left.

Actually if you look elsewhere on the BBC website you'll find what the helicam was really snapping out of the other side, namely the traffic snarled up either side of the (closed) Dartford crossing. I'm sure too that the incredible effectiveness of the stabilised cameras they use meant that it was considerably further away from the 146/RJ than it looked!

A trough system appears to have transited Heathrow at about 1400z - 1500z, and the winds have veered more in line with the Rwys 27L/R. The crosswinds were at their most testing , apparently, between 1200z and 1430z.
Rwy 23 would almost certainly have been in use for landing - in similar conditions - a few years ago. [And Rwy 27R for departures.]

The same (double?) trough system that may have cleared Heathrow at 1500z appears to have affected Gatwick between about 1400z and 1600z.
The crosswinds were at their worst between 1150z and 1450z. The wind has since veered.

Hello PKPF68-77, note that the KK/LL TAFs are identical; prepared by the same Forecaster. Hope the above comments are acceptable???

When I started flying at LGW, etc., in 1967, many of the old chaps I flew with used to complain that the Met forecasters should "try looking out of the window."

The coverage of the storm in general has been a waste of money.

It was put at the top of the news agenda when it was first forecast on Wednesday last week, and the new agencies were going to make news out of it no matter how mild or severe it was.

In the event, it was/is a typical winter storm of the type we see most years. We live in a temperate climate, for fcuck's sake.

Add it to the list of annual un-newsworthy items, along with stories such as 'Spring comes early' and 'A Levels are getting easier'.

I guess it depends on what you were expecting. There was a gust of 41KT on the 0750Z METAR, may have been higher in the SYNOPs.

40-50KT appears to be the approximate range of the maximum gusts at inland stations with 60-70KT at some coastal sites. Pretty much inline with the warnings/forecasts.

Morning shift this morning at LHR tower. Constant swaying and movement, bit like being on a ship really. Some superb landings this morning , the pick of which was a springbock , SAA 226 I think , at about 7.30 in an A340-600.

For once, Schiphol couldn't provide a runway precisely into-wind. But it probably lined up quite well during the gusts. The wind has since veered.

Was supposed to fly ABZ - LGW yesterday morning (2 hour delay due to the wind and I guess limited slots at LGW?). When we did get to LGW I must say that they did a good job up front to get us on the deck as it was rather bumpy.

Also kudos to the crew of BA2027 (LGW-IAH) who sat and waited for a heavy shower/ thunderstorm to pass over us before we took off... whilst a steady stream of orange Airbusses took off into the gloom and a B757 kept going around...

One last thing - do you feel turbulence more or less in a big jet... I mean if it's just as bumpy in a 777 as it was in a 737 does that mean the turbulence was worse as it has to shift about a larger lump of metal?

Morning All,

I flew Cayo Coco to Manchester overnight the 9th arriving Man yeterday at 7am heard all the hype about the wind and read the paper on the way across the pond, it was very very bumpy west of Ireland for about 2hrs seatbelt signs where on and cabin crew told to sit down!!

Landing at Manchester was a bit bumpy as it was a cross wind but the skipper did a good job! (Well there was 3 of them!!)

Turned up for my four leg day in the windy West to be told by ATC that the airport was closed due to 'ramp danger'. Apparently caused by a person in a position of 'authority' deciding that it was too windy to move steps, baggage trolleys etc. (wind from ATC given as 190/45-65 so fair enough) Phone rang to be told by security 'comb' that it is too windy to let the rest of my crew on the ramp to get to our crew room! They might get blown away, in spite of the fact that they managed to make it from the car park without being blown away. Is the ramp windier than the surrounding area I wonder?
Sat nursing a cup of tea for 20 mins when I noticed outside was absolute calm. Stood outside the door and the wind was around 5 kts. After some persuasion, my crew were let out and we went flying.
Wind at Take off, 250/19-24 on rwy 27.
Four hours later it was down the runway at 30-35.
By the end of the shift at 1630, it was 270/14
Like I said earlier, much ado about nothing really!

Handling the 747-400 on take off from 27R @ LHR between 1200 and 1400 hrs (don't want to be too specific:}) was quite 'interesting'. The 747 has a wet x-wind limit of 25kts, and we had to wait a short while for the 37kt gusts at the stop end to subside:hmm: to accept take off clearance.

In the end it was reported as 180/24 ish but the take off roll was 'lively' with lots of variable rudder input required and holding 5 units of aileron into wind always feels strange (about 40 degrees control wheel deflection).

The 747 is great in crosswinds when landing but more of a challenge than smaller aircraft on take off due to the degree of sweep on the wing and its propensity to lift the upwind wing and the enormous surface area of the tail.

We also of course, don't get as much practice as our shorthaul cousins;)

Not sure if you are suggesting the orange airbusses were being a bit gung ho.

The BA2027 waited initially due to lesser x-wind limits. When the cell came overhead the wind changed sufficiently for it to go.
However ALL a/c at this time elected to sit and wait for the weather to improve.

The orange busses started departing before the BA because they were nearer the holding point with other a/c scattered everywhere!
However if the BA had been at the front of the queue it would have gone first as it had accepted the weather conditions too.

Can one of you clever bods tell me what the ICAO wind is. They were giving the ICAO and the Instantaneous Wind. One being self explanatory. I was a bit busy to ask at the time. Went around (EGKK) first time and straight back for another approach which we got in!

There was an American who said on the RT that he didn't want to end up on You tube so I think he diverted to AMS!

I was on a double and got hit by both fronts. The morning one was by far the worst.

Good luck for those heading for the north tomorrow

@suggs:

I am not sure, but I believe the ICAO wind is the average wind of the last hour...or twenty minutes...something like that, so in a storm you might get cheated a bit, if winds suddenly pick up or slow down. Good job from the tower to provide the actual, the guy or gal obviously understood something about flying...

Taken from another thread on this forum

The normal, ICAO-standard wind that you will be passed by ATC at an airport is a rolling average over the previous 2 minutes (as a point of interest for anyone not familiar with this stuff, the value that you see on a METAR is averaged over the 10 minutes prior to the time of observation). Most airports are fitted with equipment that will give an 'instantaneous' w/v value - it's actually still an averaged value but, if I recall correctly, over 5 seconds.

Some pilots prefer the instantaneous value in challenging conditions and it is always available on request. The correct phraseology (in the UK) when an instantaneous wind is passed is 'Runway XX cleared to land instant surface wind XXX degrees XX knots'.


Hope this helps

Both DUBLIN and SHANNON have WSW winds gusting to 50kts. This represents 40 degrees left of Dublin's Rwy 28.

BIRMINGHAM (BHX) and LEEDS BRADFORD (LBA) appear to be the most cross-windy of the large airfields in the UK, at the time of writing, with their north-westerly runways.

The LEEDS BRADFORD TAF (see below) suggests that there will be problems for ops on Rwy 32 (the only one available) from 0300z to 1800z tomorrow (Wednesday). It is currently over 30kts component in gusts (see below).

BIRMINGHAM is already getting a crosswind component of 35kts in gusts, on Rwy 33. [Rwy 24 is only about 1200m long.] The latest 24-hr TAF (see below) has increased the wind strengths for tomorrow. The wind is now forecast to be we outside some crosswind limits, occasionally, between 0500z and 1100z tomorrow (Wednesday).

Selection of METARS, and the current TAFs for LONDON HEATHROW [NB: most recent now at the top.]

The mini-ridge of (relatively!) high pressure provided an overnight lull of moderate westerlies, but is now history. The QNH peaked at 988 at LHR between 0720z and 1020z, with the W/V backing/reducing to 210/12. The warm front/occlusion associated with the next system arrived around midday. The marked rise in dew-point was reversed as a further trough (?) transited at about 1400z, with showery outbreaks. Since then the pressure has recovered slightly, but the wind has strengthened/veered to nearly gale-force westerly (260/29-41 at 1550z).

Possibly been discussed to death already but just how bad is the internet in affecting flight deck decisions?

There was an American who said on the RT that he didn't want to end up on You tube so I think he diverted to AMS!

When we arrived at AMS today the wind was 240/25G32. There were long delays for 27 whereas 18R was wide open.

I can understand a few of the heavies having flown all night over the atlantic maybe opting for a delay, but for all the rest, is fear of pprune / youtube really that bad?

Surface W/V at 1955Z was 160/22-32. Schiphol area is very smooth, but – on the other hand – it was night-time, so you’d expect some nocturnal windshear, perhaps. My guess would be that the wind at 500ft would be about 180/40+. So the GS could be noticeably low on approach Rwy 18R.
[Particularly in a F27.] ;)

FCUK12 tells us [thanks...] that the 2-hr Trend Forecasts, still appended to some airfields like LHR, are prepared at the Met Office in [U]EXETER (like the TAFs). The observer (ATCO?) is obviously not qualified to do it.
Think what probably happens sometimes is that the METAR is broadcast before the system has tacked the TREND on to the end of it. When the omission comes to someone’s attention, the METAR has to be reissued as a “COR!”.

Agree with your sentiments, but not sure about Bert Ford - wasn't he the one who taught the padding-phrase "pushing (or any other present-participle) [U]ITS WAY" to all his protégé(e)s? **

The Dumfries librarian, on the other hand, was both wacky and cerebral. Fortunately, he's been succeeded by Rob M, who always has something interesting and different to impart, usually with dry humour, even if it's only his palindromic temperatures. Also, when at her best, Helen W is the "thinking man's crumpet".

Yes, BBC wants to use my involuntary licence fee to perpetuate the chattering-class prejudice that science and maths are fringe topics, that rarely justify inclusion in their output. And, when they have to be covered, they are generally presented in an increasingly apologetic and infantile style.

Just landed at Dublin in the Saab Loganair from City of Derry airport. After reading the METAR I can imagine that the aircraft was close to the limits (maybe someone can confirm).

Personally I had a great time and enjoyed being thrown around. Person behind me was terrified of flying. Crew did a great job of making sure she was happy.

Yesterday morning I flew Newcastle to Belfast as SLF. Quite an impressive site seeing the cloud clear overhead IOM. Landing with blue sky and light breeze.

Personally I think the media are short on stories. Nothing that different compared to previous systems that have come in from the Atlantic. I guess the forcasted low pressure got people excited.

Anyway - SLF tomorrow morning to Brussels from Dublin

Suggs,

The ICAO wind is the standard wind reading you are given.
It is the 2 min average including any gusts (greater than 10 kts above the average) in the last 10 mins.
Gatwick were passing both the ICAO and instant a lot yesterday because a lot of a/c were requesting the instant wind.

The 65-knot gust is only a 30% probability, so all book-Nigels would ignore it for planning purposes, OFFICIALLY.

Think Rwy 23's bearing is 223(T)? If the wind veered (in the gust) to - say - 263/65, that would give a crosswind component of about 40kts. Probably won't happen. :}

Quote from Chris Scott:

Think what probably happens sometimes is that the METAR is broadcast before the system has tacked the TREND on to the end of it. When the omission comes to someone’s attention, the METAR has to be reissued as a “COR!”.

COR is automatically inserted into all METARs that are re-broadcast with a Trend appended. If for some reason the Trend doesn't get added the METAR should appear without it. Most online sources appear to strip out the COR anyway. Hope that helps.

Chris Scott
12th Mar 2008, 15:26
Hi FCUK12,

What you say makes sense, and does not contradict my main point. [Only applies to airfields that qualify for TREND forecasts.]
But your theory that the word "corrected" is removed (from the amended version of the METAR) - by whatever agency broadcasts the METARS - is not what seems to be happening in practice. This definitely applies to some agencies that present METARS on the web, and ls_jet2's comment about the London Volmet is correct (pun not intended).

It is all time-consuming, when you are desperate for an Actual. Whatever fireflybob says, you can't always get the destination ATIS in time for your descent brief, and not all our colleagues have data links like ACARS. And the ATIS rarely includes a TREND forecast, unless things have changed in the last 6 years.

Here is an up-to-the-minute example from AvBrief:

On the other hand, here are the same group of METARS from ADDS (Aviation Data Digital Service ):
EGLL 121450Z 28019KT CAVOK 11/M03 Q1005 TEMPO 28020G30KT

You will note that for the 1250 and 1320 METARS, the TRENDs are missing; they have tried to avoid clutter, perhaps; but have either failed to receive the "CORs", or failed to use them when they became available.
The 1450z, however, has come out well.

Now, the UK MetOffice website:
EGLL 121450Z 28019KT CAVOK 11/M03 Q1005 TEMPO 28020G30KT
http://secure.metoffice.gov.uk/lib/template/spacer.gif

So the UK Met Office seems to be interpreting its own output of METARs correctly - hardly surprising?


Just copied the LHR 1450z METAR on "London Volmet Main" (135.375MHz):

"London heathrow at 1450 [U]corrected, Wind two-eight-zero degrees one-niner knots, CAV-O-K, Temperature one-one, Dew-point minus three, Q-N-H one-zero-zero-fife; Tempo- Wind two-eight-zero degrees two-zero knots maximum three-zero knots."

Not up in the frozen norf they're not. But this won't be on the news as

1 - the budget will now grab the headlines :{
2 - all this is going on North of Watford :}

Still 270-280 gusting 40kts at MAN with windshear reported and a couple of recent g/a which got in at the second attempt. Similar speeds at present at LPL and LBA

MAN TAF shows winds likely to decrease from 2300......

Regarding the LPL closure - I might be responsible for the start of that rumour, after telling FCA ops that Servisair were about to run for cover and not despatch any more aircraft.

Servisair decision was fine by me because I did not want to depart for BHX with winds gusting up to 60kts across the runway. Landing at Liverpool was bad enough with the wind just 10 or 20 degrees off the runway.

And Atcham Tower if that was you on the radio my I say thank you because without your string of wind reports in the last few hundred feet we would of gone round. Cheers.

Guzzler, don't blame you for staying there as things were starting to move around and I wasn't looking forward to going out to see what it was!! The turbulence coming off the hangers was making landing sporting at best, saw one baby arrival that looked very close to being No 1 engine first from where I was on stand 50.

Jonty were you in the ATR? On the RT it sounded like they landed in those conditions every leg.

Chris,

On the other hand, here are the same group of METARS from ADDS (Aviation Data Digital Service [USA]):


it depends a bit with the US data on foreign airports. First of all, they often are quite late and secondly, it depends strongly if they get properly propagated by the GTS system. Not always the case. I know of some applications which run off the US data, their METARS are always 1 behind due to the way the GTS input gets distributed into their cycle files of which ADDS and other applications are feeding. That way it can happen very well that COR's are not present.

Some other applications have the same problem. I've been fighting this end for e.g. GTS mauled messages to be still shown, particularly African TAF's which sometimes have whole sections in gobbledegook due to lousy datalines, but I'd rather have this TAF than none at all. But quite a few databases simply kill anything missing a character or two.

Best regards
AN2

Chris Scott, I agree but I don't think I said this! The company I work for doesn't have ACARS (I wish!).

One of the challenges with ATIS is co channel interference, one of the most classic ones is the EMA ATIS which is blasted out by CDG (I think) such that you cannot realistically copy same until the Luton area when approaching from the south. Apparently the DOC of arrival ATIS is only around 60 nm. But the same happened at MAN some time ago and when crews started filing reports with CHIRP they eventually changed the ATIS freq!! The weather isn't the only issue, it's the runway in use which if you second guess the wrong way requires a change of set up and brief whilst descending in some of the busiest airspace in Europe - a recipe for an altitude bust maybe?

Of course in the "olden days" on first contact with LATCC as well as the inbound routing STAR etc one was passed the Runway in use at destination. Presumably this was dropped due to issues of RT congestion and controller workload etc.

Think Super VC-10 probably wanted the lowest QFF (okay, QNH will do) in the Thread episode, hellsbrink.

Or are you being deliberately facetious? :rolleyes:

During my limited researches, the lowest reported by METARs was about 950 hPa (millibars) at Shannon on Mar10/0600z-0630z. See my post#194:

The above observations seem to show one of the eyes (do you agree. FCUK12 and PKPF68-77?) of the complex depression moving eastwards in transit just south of Shannon aerodrome. Note the steep rise of pressure afterwards, and the reversal of wind direction during the couple of hours' passage. For further info, including an explanation of wind speeds near deep depressions, see PKPF68-77's Post #163.

[Strictly speaking, of course, a QNH does not represent the precise notional sea-level pressure at a station ("QFF"). This is because a QNH is merely a device to ensure that an ICAN-calibrated altimeter, situated at the station, reads the correct elevation amsl if the QNH is set on its sub-scale. In a deep/cool depression, it is unlikely that the local pressure lapse-rate would conform to the ICAN (standard atmosphere).]

No need to worry, though (what do you mean; you weren't?).:ouch: In the case of Shannon, the station elevation is about 45 ft amsl, so the "error" is negligible.

Another point to bear in mind is that 950 could represent a pressure as high as 950×5, because decimal-5s of pressure are always rounded down, for safety reasons.

Hope this helps. Did anyone get a lower one?

14th Mar 2008, 12:13

A simple case of misreading due to a lack of Earl Grey in the system, nothing more.

As far as the lowest that day, I've seen assorted figures ranging from 950 but nothing below that.

Quote from PKPF68-77:
Pretty awesome forecasting if you know what the skills were like over 30 years ago.
[Unquote]

How true. In his day, the mid and upper-air forecasting (on which all this hinges?) was fairly hit and miss. Was once crossing Holland en-route to to Germany in a Dakota (1968), and none of our planned drifts or ETAs were making much sense at FL070. The forecat W/V in the area was about 260/30. So we used the optical drift sight to confirm the actual drift (starb'd); and stopwatch for ground-speed (TAS was 140). On that basis, we estimated the actual wind was about 310/45.

As for the (westerly) sub-tropical jet, SNAKING over North Africa in winter, the direction in the 1970s was fequently 30 or 40 degrees out. This made an enormous difference to your drift and/or GS when it was blowing at 150 kts... And the strength was equally unreliable in those days.

This may have been contributory to the shooting down of a Libyan B727 by the Israelis in about 1978. The A/C was going from Tripoli to Cairo, and completely overshot its destination, finding itself over Israeli-occupied Sinai, where the Israelis assumed it was hostile.

By the 1990s, the computer-forecast en-route winds had become uncannily accurate...
