The regs (CAR 3) state that the yellow arc is only for inadvertant excursions of airspeed
I don't see that in CAR 3. (I am aware of a reg which states that a pilot must do what the AFM states.)
How many G's can Light, Moderate, and Severe turbulence produce based upon their prescribed FPMs?
The standard equation for gust load factor:
with: a = (dCL/da) - lift curve slope - try 5 for a simple calculation
Ue = equivalent gust velocity (in ft/sec)
Ve = equivalent airspeed (in knots)
Kg = gust alleviation factor - try 0.85 for a simple calculation
W/S is wing loading in lb/sq ft
(I hope my memory has worked for the "try" numbers, I haven't had any coffee this morning yet)
