In the calculations the horizontal airborne distance is assumed to be much greater than 35 feet.

(a) True

(b) False

I have been asked this question in a national level competition.

My doubt is from Estimation of Take-off Distances topic in chapter Take-off and Landing Performance of Aircraft Performance

Best answer
The correct choice is (a) True

The best explanation: In the calculations the horizontal airborne distance is assumed to be much greater than 35 feet. The airborne distance is given by SA=\(\frac{W}{(F_N-D)_{av}}\Big\{\frac{V_{2}^2-V_{LOF}^2}{2g}+35\Big\}\) where

W is weight

D is drag

G is acceleration due to gravity

V is velocity

FN is normal force.
