Question 1

Which of the following selection statements describes the purpose of oil in an engine:
1. To lubricate
2. To cool
3. To clean by remove unwanted by-products of friction and combustion
4. To protect exposed parts
5. To help provide a seal to increase combustion efficiency

Answer 1

ALL ANSWERS CORRECT

Question 2

When a door opens in flight, what are the likely consequences

Answer 2

1. Increased noise
2. Handling unchanged
3. Door not easily closed

Air pressure equilizes as air drawn out of the cabin

Question 3

When a force is applied to a gyroscope, the resultant movement will be translated to a point ____ in the direction of the _____

Answer 3

1. 90॰
2. Gyroscopic rotation

Question 4

Typically, where would the needle point on a zero-center ammeter in flight when the battery switch is on and alternator supplying power to the busbar

Answer 4

SLIGHTLY TO RIGHT

Charging current flow from alternator to battery

Question 5

What is the source of the hot air used in carb heating

Answer 5

ENGINE EXHAUST

Air heated by heat exchanger surrounding the engine exhaust system

Question 6

A common form of low suction reading on the vacuum gauge is caused by what

Answer 6

BLOCKED AIR FILTER

Question 7

When an aircraft takes off from a highly elevated airfield on a hot day, what should the pilot reference for procedure

Answer 7

PILOT OPERATING HANDBOOK
(POH)

Question 8

What engine component ensures the correct intake/exhaust valve timing

Answer 8

CAMSHAFT

Question 9

What is the purpose of the carburettor

Answer 9

Mix fuel/air to correct raito and feed to the engine

Question 10

Will sensed pressure INCREASE or DECREASE if an alternate static source is selected
What will this do to the altimeter

Answer 10

1. DECREASE
2. OVERREAD

Question 11

What are 2 possible effects of a blocked engine cooling intake to the engine

Answer 11

1. Run Hot
2. Overheat

Question 12

In a prolonged full power climb where oil temperature is rising to the “caution” range, what 2 actions can a pilot take

Answer 12

1. REDUCE POWER
2. INCREASE CLIMB SPEED

Low airspeed means less engine cooling. Hotter engine means oil is working harder to cool, so temperature increases.
Reducing power and reducing nose angle increases climb speed whilst reducing load on the engine.
Climb will take longer, but engine should cool

Question 13

During a full and free check, both elevators should do what

Answer 13

MOVE FREELY

The elevator (each side of the fin/rudder) should move up and down

Question 14

During a full and free check, what should the rudder do

Answer 14

MOVE FREELY

full and free movement of the rudder pedals is only possible whilst the aircraft is moving (i.e. not stationary)
