If you hold 360 KTAS in a descent from FL360 to FL200,
A. Mach number increases, IAS increases, AOA decreases
B. Mach number decreases, IAS decreases, AOA decreases
C. Mach number decreases, IAS decreases, AOA increases
D. Mach number decreases, IAS increases, AOA decreases
(Answer: B As descending through the atmosphere Mach number will decrease until it becomes speed in knots, IAS will decrease because the increased air density through which the aircraft is moving, AOA will decrease as well because to maintain the decreasing TAS, the nose will need to be lowered to maintain that speeD.)
