When mooring an aircraft what type of rope should be used?

• Nylon.

• Fibre, tied tight due to stretch when wet.

• Fibre, with some slack due to shrinkage when wet.

Removal of ice by the use of deicing fluid on the aircraft, before flight.

• must be 1 hour before flight to enable fluid to be cleaned from aircraft.

• will provide sufficient prevention of ice formation until take off.

• may remove ice for a period of time depending on the airfield conditions.

Deicing fluid should be applied:

• within 60 minutes of flight.

• within 2 hours of flight

• in the whole of flight

When Ground Power is connected to aircraft, the generators are.

• paralleled to supply.

• paralleled to supply for ground starting only.

• never paralleled.

If ice and snow is found on the wings of an aircraft. Before flight:

• the snow should be removed but ice can remain because it has no appreciable affect on the airflow.

• all snow and ice must be removed.

• ice should be removed but snow can remain because the airflow will remove it.

When refueling an aircraft from a tanker, why are the aircraft and tanker bonded together?

• To discharge static electricity from the aircraft to the tanker.

• To maintain the aircraft and tanker at the same electrical potential.

• To enable the aircraft re-fuel pumps to be operated from the tanker electrical supply.

Immediately after the engine starts, check the oil pressure indicator. If oil pressure does not show within:

• 15 seconds, stop the engine and determine the trouble.

• 30 seconds, stop the engine and determine the trouble

• 45 seconds, stop the engine and determine the trouble

Do not fuel an aircraft when there is lightning within:

• 5 km.

• 8 km

• 15 km

Torque loading is carried out to provide.

• as tight a joint as possible.

• sufficient clamping without over-stressing.

• flexibility.

A metallic stiff nut.

• cannot be torque loaded.

• cannot be used in areas in excess of 250oC.

• is pre lubricated and does not need lubricating.
