a designed interrupted ignition sequence during start up when backfiring occurs

rich mixtures and low cylinder head temperatures

None

An aircraft piston engine designed with a dry sump lubricating system:

does not employ a storage tank.

employs a scavenge pump that returns the oil from the sump to a storage tank.

employs a pressure pump that tops up the oil in the sump from the storage tank.

None

The use of take-off flap will result in:

None

Tyre Creep may be monitored by:

two diametrically opposed yellow arrows painted on the tyre side wall

stretch marks on the tyre wall and possible tyre deflation.

alignment marks painted on and across the tyre wall and wheel flange

None

A magneto that inadvertently becomes disconnected from its ignition switch will:

cause the failure of one plug in each cylinder.

cause the engine to continue running when the other magneto's ignition switch is earthed.

cause a dead cut when the other magneto is switched off.

None

A coefficient of lift reaches Its maximum value:
