The Descent - Ch 12

Question 1

Schedule

Answer 1

High Alt - Constant Mach

C/O Alt - Change to constant CAS to not exceed Vmo

Question 2

Mach descent on angles

Answer 2

AOA Decreases
Pitch angle decreases
Flight path angle increases

Question 3

CAS descent on angles

Answer 3

AOA - Same
Pitch angle - Same
Flight path angle - Same

Question 4

Minimum angle of Descent

Answer 4

Vmd

Question 5

Max Angle of descent

Answer 5

VMO

Dirty confit and spoilers

Question 6

Rate of Descent

Answer 6

Max - Speed brakes out V/Mmo

Min - Min excess power required - Vmd

Question 7

Gliding Angles + ROD

Answer 7

Min Angle - VMD (jet and prop)

Min ROD - VMP

Question 8

Factors effecting gliding angle

Answer 8

Heavier AC - same angle, just faster down the slope (Vmd for the AC is faster)
Dirty Config - steeper descent angle Clean - best glide
Speed - Dirty=slower speed = steeper angle
Wind - Headwind - steeper - where your FPA = Glide angle
Tailwind - Shallower

Question 9

Glide Endurance

Answer 9

VMP = 0.76 VMD
