Final Exam pt.2

The electrical circuit from the spark plug back to the magneto is completed by grounding through the __________________.

Engine structure.

P-lead.

Cockpit switch.

When using a timing light to time a magneto to an aircraft engine, the magneto switch should be placed in the __________________.

OFF position.

LEFT or RIGHT position (either one).

BOTH position.

Two ways the magnetos are mounted to an aircraft engine are either base or flange type.

True

False

In a high-tension ignition system, the current in the magneto secondary winding is

Induced when the primary circuit is interrupted.

Conducted from the primary winding via the discharge of the capacitor.

Induced when the primary circuit discharges via the breaker points.

When inspecting an aircraft reciprocating engine what document is used to determine if the proper magnetos are installed?

Engine Manufacturer's Maintenance Manual

Aircraft Engine Type Certificate Data Sheets

Instruction for continued airworthiness issued by the engine manufacturer

Which of the following would be cause for rejection of a spark plug?

Carbon fouling of the electrode and insulator.

Lead fouling of the electrode and insulator.

Insulator tip cracked.

Magneto breaker point opening relative to the position of the rotating magnet and distributor rotor (internal timing) can be set most accurately __________________.

By setting the points roughly at the required clearance before installing the magneto and then making the fine breaker point adjustment after installation to compensate for wear in the magneto drive train.

during the magneto-to-engine timing operation.

During assembly of the magneto before installation on the engine.

What will be the effect if the spark plugs are gapped too wide?

Insulation failure

Hard starting

Shell breakdown

In an aircraft ignition system, one of the functions of the capacitor is to __________________.

facilitate a more rapid collapse of the magnetic field in the primary coil.

regulate the flow of current between the primary and secondary coil.

Stop the flow of magnetic lines of force when the points open.
