Question 3

Removal of foreign material from the engine intakes is through the what?

Answer 3

Bypass doors.

Question 4

When are the engine intake heaters inhibited?

Answer 6

The high-pressure compressor.

Question 7

NP under speed governing schedules fuel to prevent propeller RPM dropping below what?

Answer 7

780 NP

Question 8

During ground operations NH is regulated to approximately what?

Answer 8

75%

Question 9

In an aircraft featuring automatic ignition, the igniters are activated for automatic re-light any time what?

Answer 9

NH falls below 60%

Question 10

How are the engine intake heaters powered?

Answer 10

115 V variable frequency a.c.

Question 11

When do the engine Intake heaters activate?

Answer 11

When the engine intake bypass doors are open and outside air temperature is at all below 15°C.

Question 12

At low and high compression stage, Air is bled off for several purposes including what?

Answer 12

Pressurisation, air conditioning, D icing Air, oil seals and scavenging, turbine and stater vane cooling And Fuel scheduling

Question 13

Is there an alert for an abnormal fuel temperature?

Answer 13

No

Question 14

If you have a fuel outlet filter blockage what kind of caution light should you expect?

Answer 14

1 #2FuelFilterBypassCautionLight

Question 15

During operations in the flight beta range, the ECU adjust fuel flow to vary what?

Answer 15

Vary NH in order to achieve a predetermined propeller a RPM.

Question 16

In the flight idle to Disc range where engine torque is minimal, the ECU schedules only enough fuel to prevent what?

Answer 16

NP from the decreasing below 780 RPM

Question 17

What’s Max reverse NP?

Answer 17

1140 rpm

Question 18

What is NH under speed governing?

Answer 18

The ECU regulates NH at a constant 75%

Question 19

When the condition leavers are set to fuel off which valves open and which valves close?

Answer 19

Both primary and secondary valves close and the dump valve opens. This allows undelivered fuel in the fuel manifold to drain back through the flow divider and into overboard drain lines around the engine.
