if the CL of an airplane in steady horizontal flight is 0,4. An increase in angle of attack of 1 gives an increase in CL by 0.09.

if the AoA is increased by 5 by a vertical gust, what will the load factor be?

I know its 2,13 but what I dont know is why???

Please help =)

Keeping it simple

Lift = CL x zzzzzzz

Lift=Weight (Keep Genghis sedated:) ) in steady level flt (1 g)

'Load Factor' = L/W = 1

Increase CL by 5 x .09 = .45. Therefore 'Lift' = .85 x zzzz

Thus L/W = .85/.4 = 2.125
