Flashcards in The Descent - Ch 12 Deck (9):
1

Schedule

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

2

Mach descent on angles

AOA Decreases
Pitch angle decreases
Flight path angle increases

3

CAS descent on angles

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

4

Minimum angle of Descent

Vmd

5

Max Angle of descent

VMO

Dirty confit and spoilers

6

Rate of Descent

Max - Speed brakes out V/Mmo

Min - Min excess power required - Vmd

7

Gliding Angles + ROD

Min Angle - VMD (jet and prop)

Min ROD - VMP

8

Factors effecting gliding angle

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

9

Glide Endurance

VMP = 0.76 VMD
