January exams, please read
Good luck to everyone who's doing their January ATPL exams.
Now I have a question from Performance.
You descend at a constant mach, what is going to happen to your angle of pitch?
a) increase
B) decrease
c) remain the same
d) depends on temp.
Since you descend at M then I assume you'll have a TAS increase and that's why I went with the angle of pitch as increasing.
L=CL x speed x 1/2p
Since speed goes up, CL has to increase to remain constant but then I didn't factor in the density, so if P and S increase then there's more a reason for CL to decrease, am I nuts????
Maybe someone can help me see what I'm not seeing.
