The engine driven fuel pump the oil pump the DC starter/generator.

Question 16

What’s driven by the propeller reduction gearbox?

Answer 16

A propeller control unit PCU,A PCU oil pump, a propeller over speed governor and an engine driven hydraulic pump.

Question 17

What is Beta range?

Answer 17

Beta range is where the pilot is directly controlling the propeller blade angle.

Question 18

Engine fuel Scheduling is controlled by what?

Answer 18

Mechanical fuel control unit MFC, and an electronic control unit ECU

Question 19

In manual mode fuel control is relative to what?

Answer 19

Power lever angle PLA and condition lever angle CLA.

Question 20

When the ECU mode is set on the ECU received input from what?

Answer 20

Potentiometer is sensing power lever angle and condition lever angle

Question 21

During normal flight operations with the power levers forward of the flight beta range, propeller blade angle is governed by what?

Answer 21

Governed by the propeller control unit which regulates propeller speed in response to the condition lever setting

Question 22

During normal flight in the forward flight range as the power levers are retarded, the propeller control unit does what?

Answer 22

The PCU reduces blade angle as it attempts to maintain the commanded propeller rpm, referred to as NP

Question 23

In the Disc range, propeller blade angle varies between what?

Answer 23

+20° at flight Idle to +1.5° at Disc detent

Question 24

What are the propeller blade angles in the reverse Beta range?

Answer 24

Blade angle changes from +1.5° at Disc to -11° at Max reverse stop

Question 25

When the condition leavers are in the Min position propeller rpm is Governed at approximately what?

Answer 25

900 NP

Question 26

Why when the engine ECU mode selector switch Is set to manual do You get a slight increase in power?

Answer 26

Because during normal operations the Eletronic control unit is modifying the fuel input to the mechanical fuel control unit in order to optimise fuel scheduling when the engine ECU mode is in manual, unmetered fuel is provided to the applicable engine.
