A

Rotor

28
Q

It is anaircraft magnetothat incorporates a single drive source powering two magnetos

A

Dual

29
Q

It contains the ignition harness contains an insulated wire for each cylinder that the magneto serves in the engine.

A

Ignition Harness

30
Q

The type of switch used varies with the number of engines on the aircraft and the type of magnetos used.

A

Ignition switch

31
Q

It is any piece of equipment that converts mechanical energy into electrical energy by electromagnetic induction. Generator

A

36
Q

8 TYPES OF AIRCRFAFT STARTER

A

Inertia
Direct hand cranking
Pullcord
Coffman
Electrical
Pneumatic
DC electric motor
Starter generator

37
Q

two ways to complete the primary circuit

A

Through close breaker points to ground
Through close ignition switch to ground

38
Q

In the inertia starter, energy is stored slowly during an energizing process by a manual hand crank or electrically with a small motor.

A

TRUE

39
Q

The starter must turn the engine up to a speed that provides enough electricity through the engine for fuel to be ignited. Then, the starter must continue to help the engine accelerate to a self-sustaining speed. Turbine engine starters have a critical role in starting of the engine.

A

FALSE

40
Q

Reciprocating engines need only to be turned through at a relatively slow speed until the engine starts and turns on its own

A

TRUE

41
Q

If the starter turns the turbine engine up to a self-sustaining speed, the engine start process will not be successful.

A

TRUE

42
Q

A starter is an electromechanical mechanism capable of developing large amounts of mechanical energy that can be applied to an engine, causing it to rotate. Reciprocating engines need only to be turned through at a relatively slow speed until the engine starts and turns on its own

A

TRUE
