06 Angle Of Climb

Question 1

What is the equation for the Gradient %?

Answer 1

Gradient % = ((T - D)/W) * 100

Question 2

Describe Vx and how it is different for Jet’s and Prop’s

Answer 2

• Vx is the speed for the best Angle of Climb
• For a Jet Vx = Vmd (4 degrees AOA)
• For a Prop Vx = Vmp (> 4 degrees AOA)

Question 3

What are the factors which affect Angle of Climb, Vx and how?

Answer 3

• Increasing AC Mass: Decreases AOC, Increases Vx
• ‘Dirtying’ the AC Config: Decreases AOC, Decreases Vx
• Inc. Alt. Temp. CAS: Decreases AOC, Vx remains cons. for Jet
• Inc. Alt. Temp. TAS: Decreases AOC, Increases Vx
• Engine Failure: Decreases AOC, Decreases Vx (Jet, inc. for Prop)

Question 4

How does Wind effect the Angle of Climb and the Flight Path Angle?

Answer 4

• Wind has no effect on the Angle of Climb

- A headwind will increase the Flight Path Angle and a tailwind will reduce it
