Chapter 19: Climb

Question 1

Climb Angles (3)

Answer 1

Flight Path - groud to RAF
3D AoA - RAF to AC longitudinal
Pitch Angle - ground to AC longitudinal

Question 2

Fligh Path Angle Calculation

Answer 2

sin(γ) = ( T - D ) / W

Question 3

Climb Load Factor

Answer 3

n < 1

Question 4

Best Angle Climb (Jet)

Velocity, Explanation

Answer 4

Thrurst is constant with speed

Vx @ Vmd

Question 5

Best Angle Climb (Piston)

Velocity, Explanation

Answer 5

Thrust decreases with velocity
Vx near Vs (dangerous)
Instead use Vmp

Question 6

Climb Gradient
Gradient Calculation, Justification?
Gradient Relationship to Flight Path Angle

Answer 6

G = height / distance = tan (y)
at small angles, tan(y) = sin(y)
so G = ( T - D ) / W

3° = 5%

Question 7

Flight Path Angle vs Pitch

can it be negative?

Answer 7

Flight path angle > 0

pitch can be negative or positive

Question 8

Flight Path Angle vs Climb Angle

Difference

Answer 8

Flight Path Angle = with headwind / tailwind

Climb angle = theoretical value based on T, D, W
