Wind speeds that ground aircraft

gebbel

I'm due to fly on an Etihad flight on Friday evening from Dublin. The weather forecast is looking increasingly ominous from now until then. Just wondering about how windy it must be before airlines decide not to risk it? Is there a max wind/ gust speed above which the call is made not to fly? Thanks

Good question ...

OH is flying out of cork at 6 AM tomorrow morning to AMS

And is flying back Friday evening

It's a combination of not just speed but also direction. Different aircraft have different crosswind limits, so that is the determining factor. For Dublin we usually get problems with a strong wind from 220-230 ° (SW) as this is around 60 ° off both runways 28 and 16, meaning full crosswind component whichever one you choose. Windshear is a problem, though, no matter what direction.

In any case Friday's winds are not set in stone yet so I wouldn't be worrying just yet.

Not set in stone but the weather gurus on this website are fairly unanimous in their forecast, and they are rarely wrong. No point in worrying I suppose, out of our control anyway.

if etihad still use Boeing 777 for the route then for landings dry or wet, max crosswind usually is 38-40kt (which is about 75km/h). I suppose it depends on the company policy, but typically for take-offs I believe the value is 40kt for dry, down to just 15kt (28km/h) if its really wet, there's standing water on runway or ice/snow.

Wind rarely blows directly from 90° angle (what are the odds?) so narrower angle allows bigger tolerance towards wind (it decreases the crosswind component)

According to my ticket it's an Airbus A330-200.

these numbers are about the same for most jets, includind a330

Op....I think you'll be ok. The inbound aircraft looks like it will land on rwy16 ....the winds veer onto a SW direction later looking like 38kt. You'll prob use the westerly rwy for departure and these winds should be inside the 40kt crosswind limit of the 330 wet/dry provided braking action good.

See http://www.met.ie/forecasts/5day-ireland.asp It gives a good template of what to expect. Enjoy your trip.

Evening EY flight is an A332, the morning flight is the B773.

I was going to give a big 'lecture' on winds an stuff but our man is probably toasting himself somewhere warm by now:D
