ATPL Performance Question
Hi!
Im going through the "General Principles: Climb and descent" chapter in the oxford book "Performance" and would be pleased if some of you could explain the answer on this question:
With the flaps in the take-off position, compared to the aircraft clean, the climb gradient (i) and the speed for best climb angle (ii) will:
------(i)------(ii)------
A: Decrease Increase
B: Increase Decrease
C: Decrease Decrease
D: Increase Increase
The answer sheet says that C is correct. Why is that?
With flaps settings compared to clean config, Vx will decrease...but shouldn't the climb angle increase relative to the ground?
