I've got to say I did fully expect there to be some regs ensuring these things would work as expected in a 'controlled eviroment' and 25kts is not too extreme so I'm going to call that the 'controlled eviroment'. But what happens when you've got twice that amount of wind, or three times?
At what point do they unpredictable/unsafe? If only tested for 25kt, is 25 the limit? What about 40kts? Or 60kts? What happens when that limit is reached? Presumably, if you can't ensure the safe evacutation of an aircraft you shouldn't get yourself into a position of having people on board that can't readily get off - i.e. don't depart for a destination that is reporting such high winds...
Thoughts?
