3. The revolutions per minute that the propeller is rotating

Question 6

In an aircraft with a fixed-pitch propeller, what is the indicator of engine power?

Answer 6

Tachometer

Question 7

What is varied to maintain a constant propeller rpm (revolutions per minute) in a constant-speed propeller system?

Answer 7

Pitch of the propeller

Question 8

In an aircraft with a constant-speed propeller, what is the indicator of engine power?

Answer 8

Manifold pressure

What is used to indicate the power of turboprop/turboshaft engines?

Answer 18

Torquemeter

Question 19

What turbine engine indication typically represents the rotational speed of the low-pressure compressor and is presented on the indicator as a percentage of design rpm?

Answer 19

N1

Question 20

What turbine engine indication typically represents the rotational speed of the high-pressure compressor and is presented on the indicator as a percentage of design rpm?

Answer 20

N2

Question 21

What possibility exists due to the design and function of a turbine engine’s air inlet?

Answer 21

Ingestion of debris

Question 22

Where are aircraft fuel tanks normally located?

Answer 22

Inside the wings

Question 23

Why are fuel tanks vented to the outside?

Answer 23

To maintain atmospheric pressure inside the tank

Question 24

What happens when a tank is filled with cold fuel from underground storage, then left outside in the sun?

Answer 24

The fuel expands and can drain overboard
