The descent, Landing, SEP part 1 (04-06-18) Flashcards
How does NGM relate to NAM?
NGM = NAM x GS/TAS
What happens to IAS when descending at a constant M?
It increases
What happens to AoA when descending at a constant M?
It decreases
What happens to CL when descending at a constant M?
It decreases
What happens to Gradient % when descending at a constant M?
It increases
What happens to TAS when descending at a constant M?
it increases
What happens to Pitch when descending at a constant M?
it decreases
What happens to RoD when descending at a constant M?
it increases
What happens to AoA when descending at a constant IAS?
It remains constant
What happens to CL when descending at a constant IAS?
it remains constant
What happens to gradient % when descending at a constant IAS?
it remains constant
What happens to TAS when descending at a constant IAS?
It decreases
What happens to pitch when descending at a constant IAS?
It remains constant
What happens to RoD when descending at a constant IAS?
it decreases
Why does pitch decrease when descending at constant M?
in the descent we must speed up as an IAS by pitching down.
Why does gradient of descent remain constant when descending at constant IAS?
thrust remains constant and weight is assumed to also remain constant.
Drag remains constant with decreasing altitude and therefore gradient.
What determines RoD?
Thrust or power deficit
What is the speed for best range in the descent?
Vmd
What speed is best for obstacle avoidance?
Best range speed (Vmd)
What is the speed for best endurance?
Vmp
What is the effect of increased mass on the range of a glide?
There is no effect as long as Vmd is still flown
What is the effect of increased flap on the range of a glide?
Range decreases, due to clean wings having the best range.
