There's a piece of film (sorry I haven't got it, nor a link to it) showing slides deployed in anger on a 747 which wound up wrapped round the fuselage due high winds. Not sure where, but West coast of the US, I seem to recall. Scary if you're trying to get off the a/c, frustrating if you're on the ground, trying to rescue people.
How can you set a wind limit for the use of slides? If you gotta get off the a/c 'cos it's ablaze, you gotta get off! Are we saying that if the wind is reported > a value, you don't deploy the slides? What else can you do, make everyone jump?
OR, do we say, if the wind is forecast to be > a value, WE DON'T FLY. That makes more sense to me.
Cheers,
