17.3 Power Leaver Operation

Question 1

Lever movement from A to B?

Answer 1

Blade angle remains the same
Speeder spring will remain where it is
RPM increases with fuel flow
At position B constant speeding will occur
Propeller starts to move off the ground fine pitch stop

Question 2

Lever movement from B to C?

Answer 2

Governor now regulates the propeller, rather than fuel flow directly
Blade angle responds to increased fuel flow to absorb extra power
Maintaining constant RPM

Question 3

Constant speeding means the governor is regulating what?

Answer 3

The speed of propeller within certain RPM ranges

Question 4

Lever movement from C to D?

Answer 4

Fuel flow increase
RPM increases to maintain optimum blade angle

Question 5

Lever movement D to E?

Answer 5

In take off, more RPM is needed
The power lever moves the speeder spring down, this reduces blade angle allowing prop RPM to increase
