Thanks, fireflybob, but not all of us carry arbitary "definitions" in our head. That's why we sometimes need guidance on same.

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

Amsterdam-Schipol is just as windy, but they have no fewer than 3 north-south runways, in addition to all the others: -

He/she may have been "struggling", as the BBC puts it, but if so it was well disguised.

Nice one... :ok:

Just to add to the fun, we have TS south of LGW

FlyboyUK 10th Mar 2008 14:21

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.

Andy Rylance 10th Mar 2008 14:27

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.

Mr Shoesmith - you may have the honour of ensuring my facts are straight....

WHBM 10th Mar 2008 14:36

Well I'll bet that on a difficult day London City tower really appreciated having to handle a helicopter getting right in behind the arrival. Wonder if they got permssion or just asked for a transit north to south behind the landing aircraft.

to see live weather from your sofa from LHR (near)
 
:)To see the weather live at White Waltham ten miles west of LHR log on to www.wlac.co.uk and hit live weather its very changeable !!

Jenson Button 10th Mar 2008 14:48

Thanks to the LHR controllers today (both tower and radar), it was quite a handful on both departure and arrival. Just glad we got back on the deck, i don't mind sporting but today was grim.

Well ... it's not just how low the millibars go but how far apart the *isobars* are spaced.

20mi N of London there's a modest wind. Nothing to shout about. Certainly no STORM for sure.

Bristol is just coming out of the centre now which was calm, and it certainly is kicking off now as the pressure increases.

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.
(you flying in to LCY today Captphill:D)

Thanks for posting that chart PKPF68-77.

On the night of that storm our garage roof blew off and large parts of it landed in the bathroom of our house (in Gourock, west of Glasgow) - much to the consternation of my mother who was expecting a baby 13Alpha at the time :uhoh:.

Yellow Snow 10th Mar 2008 16:40

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

Suzeman 10th Mar 2008 16:48

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.

BBC helo footage of LCY approach
 
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!
