Va compared to Rough Air Speed
I fly turbo-props for a living, not been able to get on any jet aircraft yet, though hopefully should be there soon!
My question concerns the difference between Va and the rough air speed. Va is almost always lower than rough air speed, why is this? Va is supposed to allow safety margins above stall at the limit of the airplanes g-loading envelope, correct? If so why wouldn't this also cover the speed to be flown in rough, turbulent air when the gust conditions encountered can replicate the same conditions affecting Va.
I've run across a few chaps who would like the speed flown in turbulence to be far below the rough air speed in the FCOM so I am curious as to what should be flown.
Any input would be greatly appreciated.
Thanks!
