Climb Power And Performance

Question 1

Two methods of climb

Answer 1

●Trade Kinetic Energy for Potential Energy
●Use Propulsive Energy Above That Required for Straight & Level

Question 2

Climb forces

Answer 2

●Perpendicular to Flight Path
●Parallel to Flight Path

Question 3

Lift and drag during climb

Answer 3

Lift Less in Climb Than Level Flight

Drag Less in Climb Than Level Cruise

Question 4

Rate of climb

Answer 4

Vertical Velocity is Rate of Climb.
Excess Power Above Required For Straight & Level.
Dependent on Weight .
Best Rate of Climb Speed (Vy)- Airspeed That Provideds The Greatest Gain Of Altitude In The Shortest Time.
Best Rate of Climb Speed
●Maximum Excess Horsepower
●Maximum Rate of Climb
Change With Altitude.

Question 5

Angle of climb

Answer 5

Best Angle of Climb Speed (Vx)
●Airspeed That Produces The Greatest Gain In Altitude For The Shortest Horizontal Distance
Best Angle of Climb
●Minimize Horizontal Velocity
●Maximize Vertical Velocity
Effect of Wind
●Reduce Horizontal Velocity
Change With Altitude

Question 6

Absolute ceiling

Answer 6

Best Rate & Best Angle Converge
Altitude At Which Rate of Climb Is Zero
No Excess Horsepower
Flight Possible At One Airspeed

Question 7

Service ceiling

Answer 7

Altitude At Which Rate of Climb Is 100 fpm

Question 8

Normal climb

Answer 8

Use Best Rate of Climb Speed
●TAS Increases With Altitude
●IAS Decreases Slightly With Altitude

Question 9

Cruise climb

Answer 9

Provides
●High Forward Speed
●Good Rate of Climb
●Engine Cooling
●Better Forward Visibility
Speed At Which Rate of Climb Does Not Degrade Significantly

Question 10

Maximum angle of climb

Answer 10

Used To Clear Obstacles At A Short Distance From The Runway
Short Time Periods
Maximum Excess Thrust
Close to Stall
