my first trip in the left seat of a b747 "all on my own" was a double rugby charter DUB-EDI, in marginal x-winds.
on taxi in at edi ATC said the guidance system for my stand had just blown away, but if i looked up at the roof of the building i would see a marshaller.
sure ,nuff one guy on de sticks....two holding him down!
enjoy your weekend.

... and just to emphasise the point:

940mb = 2190 feet away from Standard

Careful out there, especially if your aircraft has been standing for a few days and the altimeter is on a much higher setting.

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.

Ok then I am going to make a prediction - I bet the wind will not be as strong as they are forecasting at the moment. What odds will Ladbrokes give me I wonder?

Even given all the computing power, weather forecasting is still an imprecise science.

gross-wind landings,
...
"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...

Low barometric pressure? My tip is always give the screen a little tap before you land

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

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.

Getting back to Cardiff at just before midnight on Sunday. Waterproof trousers and loose wellies are in order, methinks!

I'm Glad i'm rostered for the simulator Monday / Tuesday
Don't worry. Strong winds can be programmed in for you. Would 100kts straight across the runway be ok?

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.

Ok, I am now officially "looking forward" to my Glasgow->London City Airport flight on Monday morning.

Still, it's at 8:30am so we're hardly the first plane of the day - the pilots will know what to expect.

Best thing is, I understand we wouldn't even be in the air if this was worrying the airline, so if my flight goes ahead, I'm going to make sure I enjoy the experience - coming into LCY as PAX is as close as I'll get to landing on a carrier

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.

Suggest those of you in the hold at BNN keep a good look out below around late morning when the transatlantics start rolling. Good old US crews the favourite for climbing to FL still on the QNH.

Im more worried about a Truck blowing over on top of me car driving into work than Operating in such Winds...

Hopefully it'll be straight down the Runway for most of us...

Keep your wits about you, keep the girls strapped in and take plenty of extra Fuel!

Be Safe guys.
