Correct Answer : Drag D = W*cos (gamma)
Explanation : Above equation is used to provide information about drag of atypical glider. Drag can be given by, Drag D = W*cos (gamma) where, D is drag, W is weight of the glider and gamma is the glide angle.
Correct Answer : Option (D) : 147.6
Explanation : Average velocity at Flare = 1.23*stall speed = 1.23*120 = 147.6 knots.
Correct Answer : Option (C) : 26.4 unit
Explanation : For military aircraft, Approach speed = 1.2*stall speed = 1.2*22 = 26.4 unit.
Correct Answer : Option (A) : 90.90
Explanation : Stall speed = touchdown speed/1.1 = 100/1.1 = 90.90.
