● What does maximum lift-to-drag ratio provide?. Answer: Maximum
range and glide distance
● How does lift act in relation to relative wind?. Answer: Perpendicular
to relative wind
● What effect does an aft CG have on an aircraft?. Answer: Less stable

Quadruple
● What happens when leaving ground effect?. Answer: Increased
induced drag

increases?. Answer: Decrease rate of turn
, ● At what condition does an airplane stall?. Answer: At the same angle
of attack
● Below L/D max, what primarily causes total drag to increase?.
Answer: Induced drag
