It remains constant

Question 14

What happens to RoD when descending at a constant IAS?

Answer 14

it decreases

Question 15

Why does pitch decrease when descending at constant M?

Answer 15

in the descent we must speed up as an IAS by pitching down.

Question 16

Why does gradient of descent remain constant when descending at constant IAS?

Answer 16

thrust remains constant and weight is assumed to also remain constant.

Drag remains constant with decreasing altitude and therefore gradient.

Question 17

What determines RoD?

Answer 17

Thrust or power deficit

Question 21

What is the effect of increased mass on the range of a glide?

Answer 21

There is no effect as long as Vmd is still flown

Question 22

What is the effect of increased flap on the range of a glide?

Answer 22

Range decreases, due to clean wings having the best range.

Question 23

What is the effect of changes in AoA from Vmd on the range of a glide?

Answer 23

Range decreases

Question 24

What is the effect of wind on the range of a glide?

Answer 24

HWC reduces range

TWC increases range

Question 25

What is the effect of increased mass on the endurance of a glide?

Answer 25

It decreases

Question 26

What is the effect of increased flap on the endurance of a glide?

Answer 26

It decreases, due to clean wings being best.

Question 27

What is the effect of flying an AoA different to Vmp on the endurance of a glide?

Answer 27

It decreases

Question 28

What is the effect of wind on the endurance of a glide?

Answer 28

There is no effect

Question 29

What are the benefits of a continuous descent approach?
