Re: airport sound barriers

Thanks for your replies. I was able to convince several parties that the design wind would govern over the lesser jet wash. It also helped that the wall is parallel to the runway or taxi way. Makes you wonder about people sometimes.

You beat me to the punch.  I was just about to comment that flights would likely be grounded if a significant storm was passing through...

I am not sure if ASCE or similar Canadian codes have a specific
opinion or load combination for this. But I would think that the
probability of planes taking off during a significant wind would be
quite low if not impossible. I think in absence of other requirements
I would check it 2 different ways:
Full wind pressure
Full plane pressure + wind pressure at max wind speed allowed for
plane takeoffs/landings (maybe available from FAA or the Canadian

However, a quick google search seemed to indicate large commercial
planes can be landed in 50-60+ knots... And they said there is no
established speed, like everything else, it depends...
