What happens to the speed of Vx and Vy with increasing altitude?
A) Both remain the same
b) Vx remains const. and Vy increases.
C) Vx Inc. and Vy remains const.
d) Vx remains constant and Vy decreases.
Correct answer is D but is it because ROC would decrease for increase of altitude and Vx is basically BEST angle of climb which is least amount of ground covered for every vertical unit achieved? (since Vx doesn't care about time it takes compared to ground)
Barking up the wrong tree am I?
Other question
With which conditions would one expect Vmc to be the lowest?
A) Cold temp,low altitude, low humidity
b) hot temp, low pressure altitude, high humididy
c) hot temp, high pressure altitude, high humidity
d) cold temp, high altitude, low humidity
Answer given is C but that doesn't seem to make much sense to me. Anyone care to clarify?
By the way, Merry X-mass and a happy new year!
