Chapter 20: Descent & Glide

Question 1

Descent Load Factor

Answer 1

n < 1 ( L = W cos(y) )

Question 2

Descent Flight Path / Gradient

Answer 2

G ~= sin(y) = ( D - T ) / W

Question 3

Gliding

Gradient, Range

Answer 3

G ~= D / W

Range = ( L / D) * H

Question 4

Best Glide / Endurance

Velocities, Relationship?

Answer 4

Vmd - best glide
Vmp - best endurance
Vmp = .76 Vmd

Question 5

Effect of Mass on Glide / Endurance

Answer 5

Glide -> none

Endurance -> Vmp faster -> endurance shorter

Question 6

Effect of Headwind on Glide / Endurance

Answer 6

Glide -> steeper descent to stay less in HW -> range decreased
Endurance ->?
