Climb Speed And Calculations - Ch 8

Question 1

Vx

Answer 1

Best AoC (max) for obstacle clearance

Question 2

Vy

Answer 2

Best RoC for getting to alt quickly and efficiently (most Fuel efficient speed)

Question 3

Initial Climb

Answer 3

Flown at constant I/CAS - same dynamic pressure

Question 4

As Alt. Increases

Answer 4

Lift and Drag remain constant

TAS will increase

Pitch Angle will decrease

Question 5

Climb Schedule

Answer 5

Use to Climb on constant CAS at lower altitudes and constant Mach number at high altitudes

Question 6

Q: RoC at change over alt….

Answer 6

Will briefly increase along with AoC

Question 7

Climb and Descent Rule that works for both

Answer 7

CAS Increases Change over alt. Decreases

Mno Increase Change over al. Increases

Question 8

ECON Setting

Answer 8

Based on Vy and weighted by the cost index

The greater the cost index, the larger the CAS and Mno used in climb

Question 9

Above the C/O Altitude

Answer 9

AoA increases because CAS decreases
AoC reduces
Pitch angle Reduces

Question 10

Minimum Gradients Allowed
