Had a discussion with a fellow pilot today about gust factors. Are you guys adding half of the gust factor or the full gust factor to the Vref speed? I have always been taught 1/2 the gust factor and the other has been taught the full gust factor. What is everyone esle doing"?... did a few searches on the .net and have found it mentioned both ways as all, what is the majority using? thanks
 
Depends on your company's take on it....I've heard of some that add 1/2 the steady and all of the peak up to 20(if memory serves.....and this was on heavy's) and others that add 1/2 the gust.
 
Standard rule of thumb is usually

Half the steady wind + all the gust not to exceed 20kts
 
Check your AFM. The F900 AFM is all the wind, half the gust with a limit of 20 KIAS.


Check YOUR afm... or page n-12 in the FSI check list...
"All wind gust + 1/2 steady wind (20kts maximum)"

All Falcons are this way...

We operate a BE-400A and the book states that "Final approach speed shall be no less than Vref +5 KIAS, nor greater than Vref + 15 KIAS." I apply 1/2 the steady state wind plus the entire gust not to exceed 15 KIAS.

I meant to say, add half the gust factor,
sorry it won't let me edit my post for some reason.
