An aircraft is flying at MACH 0.84 at FL 330. The static air temperature is -48(degrees)C and the headwind component 52 Kt. At 1338 UTC the controller requests the pilot to cross the meridian of 030W at 1500 UTC. Given the distance to go is 570 NM, the reduced MA

A: 0.78
B: 0.80
C: 0.76
D: 0.72

 

 

 

 

 

 

 

 

Answer: B

During a descent at constant Mach Number, the margin to low speed buffet will:

A: increase, because the lift coefficient decreases.
B: remain constant, because the Mach number remains constant.
C: increase, because the lift coefficient increases.
D: decrease, because the lift coefficient decreases.
