Flying and Wind

[creamegg]

Flying tonight into dublin and supposed to be very windy. What is the highest wind they will fly in?

[PAXboy]

That depends upon:


The type of aircraft.
Manufacturer's limits.
Company limits.
Speed of wind - steady.
Speed of wind - gusting.
Angle of wind to the runway.
Which runway is in use.

All of these will be calculated by the pilots before leaving the cruise and throughout the approach. The wind can change speed and direction very quickly(!) so the tower will advise the crew on how the wind has been behaving in the last 30 minutes as an indication as to what it might do in the next 30 minutes.

ok, I know it is an A320 and it's with aer lingus. There are a few flights cancelled already.

After landing at Heathrow last Sunday during Storm Clodagh I would say virtually anything but in truth it depends on the aircraft's operating limits in terms of wind strength and direction.

The forecast Dublin weather is:

TAF EIDW 041100Z 0412/0512 22020G32KT 9999 FEW018 BKN040
BECMG 0412/0414 22024G38KT
BECMG 0414/0417 22028G43KT
TEMPO 0421/0512 22030G48KT 5000 -RA BKN013

This means from now the forecast is 220/28G43 ie southwesterly @ 28 knots gusting to 43 knots.

The most favourable runway would be runway 28. The wind would be from 60 degrees left of the nose, so almost all across, however when the wind gusts to the stronger value, it usually veers (so rather than from the southwest, will probably be more westerly, and therefore less of a headwind).

I would say that it looks within limits for an A320, but the approach may be a bit lumpy and turbulent. I would have full confidence in the Aer Lingus flight crew.

I thought it was a Q about reduced cabin pressure and flatulence :E

My last two B747 companies set limits of:

.........................................Company 1.....Company 2

Ldg x-wind..............................28kn............36kn
Wet.......................................28kn............25 kn
Contaminated ice/snow/slush......10kn............15kn
Aircraft ops on ground..................................65kn

That's just a few figures. There are a lot more for different conditions, autoland etc.

My last company was :

B747-400

- landing 36 dry/ 32 wet/ 15 contam

A320 family

- landing 33 gusting 38 (wet and dry)

take off not relevant in this case!

[creamegg]

Thank you all for your very thorough explanations, alas it was all in vain, as I got held up in traffic outside Manchester (travelling from lincoln) and ended up missing check in :(

Your flight departed and arrived about 40 mins late possibly due to wind.

EI cancellations were mainly the regional flights operated by turboprops.

Almost 60 Ryanair cancelled today from DUB. Most other airlines were fine. Anyone know why? Hardly the wind. That's a shocking figure.

[HeartyMeatballs]

Gusting 46 whilst 60 degrees off could have something to do with it. Why do you think they cancelled them?

[alserire]

Why do I think they cancelled them?

I don't know. That's why I asked the question.

So why were no EI jets affected then? Sixty odd 737/800s cancelled but no A320/321/330s.

Sorry for not being more precise in my question. If you're not prepared to answer it without being sarcastic then leave it. I'm not that desperate to know.:=

[Sober Lark]

alserire, if you check flight arrivals / departures at DUB (try flightradar24) you'll see plenty of airbus cancellations.


Some felt all the cancellations today were part of Ireland's attempt to meet our EU emissions target 2015.

I was supposed to fly on this flight too. Wind at BHX was ok, when I checked in. I was not aware of how severe the wind was I'm Dublin at that time. I asked crew about conditions and when I heard it could be very bumpy on approach I asked if I could off-load. I have a dreadful fear of turbulence and I also lost my Mum a few weeks ago, so it was all too much for me.to take.


I am interested to hear from anybody who flew though to know was it very bad it was and whether there was a go around.

Thanks,

Maddie
