Aircraft Tech

#1. What is the most important part of spin recovery

Elevator forward, opposite rudder

Use full power

Back pressure to stop the nose from dropping further

#2. What is the main purpose of having two magnetos?

Enables the engine to run hotter

Reduces pre ignition

Reduces detonation

Efficiency and redundancy

#3. What can lead to damage to an engine as a result of leaning?

Pre-ignition

Detonation

High oil pressure

Carb icing

#4. Angle of attack is?

The angle between the chord line and the longitudinal axis of the fuselage

The angle between the relative airflow and the lateral axis of the fuselage

The angle between the relative airflow and the chord line

The angle between the chord line and the camber line

#5. If the engine of an airplane is permitted to idle for a long period of time while on the ground

A hydraulic lock may develop in one or more cylinders

The lean mixture may cause the engine to miss or qui

The result may be an excessively high oil pressure

The spark plugs may become fouled

#6. Best rate of climb occurs at 75kts, if you were to climb at 60kts…

You would climb faster due to a higher nose attitude

Climb slower due to having a slow airspeed

You will climb at the same rate, it depends on the wind

Your climb performance will be reduced, you are not at your best rate of climb

#7. For most light aircraft, the mixture control is left in FULL RICH for the climb, unless it is an extended climb to an altitude in excess of 3,000 ft. The reason for this is to..

Ensure that maximum power is available for the climb

Ensure the mixture doesn’t become lean due to the increase in altitude

Ensure the spark plug does not become too far advanced, possibly resulting in pre-ignition

Provide an enriched mixture which aids in cooling the engine

#8. A turbocharger is connected to?

An impeller placed in the exhaust

The back of the crankshaft

An impeller placed in the carburetor

The impulse coupling

#9. If the static vent becomes blocked what instruments will not work?

DI, AH, ASI and Turn and Slip Indicator

DI, VSI, ASI, and ALT

ALT, DI, ASI, and VSI

ALT, VSI, and ASI

#10. Which statement is true regarding aircraft engines that are equipped with a fuel injection system instead of a carburetor?

Vapour locks during ground operations on hot days are less apt to occur with fuel injection

A disadvantage of fuel injection is the difficulty experienced in cold weather starting

Slow throttle response is one of the disadvantages of fuel injection

Fuel injection provides better fuel management and fuel distribution to the engine

#11. Which factors increase the stall speed?

Weight, flap, ice, power

Ice, weight, loading, damage

Power, flap, loading, weight

Weight, ice, loading, flap

#12. The co-efficient of lift is made up of which 2 components?

Air density and Velocity

Angle of attack and Airspeed

Shape and angle of attack

None of the above

#13. What are the 4 forces acting on an aircraft in straight and level flight?

Lift, Weight, Power and Drag

Weight, Drag, Thrust and Lift

Yaw, Roll, Pitch and Thrust

Loading, Drag, Thrust and Lift

#14. An aircraft is at an airfield with an elevation of 800ft, the QNH at the aerodrome is 1030hPa, what is the pressure altitude?

290ft

510ft

800ft

1310ft

#15. Carb Ice will most commonly occur?

At high altitudes

On hot days

On cold/warm days with moisture present

On the ground on frosty mornings

#16. Flying at 3000’ compared to 10,000’ at a constant indicated airspeed you will?

Travel slower due to increased temperature

Have a higher groundspeed due to more power

Have a greater true airspeed, due to increased density

Have a lower true airspeed, due to increased density

#17. In comparison to fuel injection systems, float-type carburetor systems are generally considered to be..

Equally susceptible to icing as a fuel injection unit

Less susceptible to icing than a fuel injection unit

Susceptible to icing only when visible moisture is present

More susceptible to icing that a fuel injection unit

#18. If the QNH changed from 1017 to 1012 with no correction to your altimeter while maintaining indicated altitude, you

Read low and be high

Be low and read low

Read high and be high

Read high and be low

#19. You are on final to land with Carb Heat on, before landing you should?

Turn the carb heat off, to avoid clogging up the air intake

Turn the carb heat off, to allow max power for go round

Leave carb heat on to prevent carb icing

Lean mixture, to attain a better combustion

#20. The primary means of recovering from a stall is to?

Increase power

Lower the flaps

Reduce the angle of attack

Use rudder to prevent a wing drop

#21. The QNH is 1013hPa. If the aerodrome elevation is 300 ft, the pressure altitude at aerodrome level will be?

300 ft

840 ft

90 ft

Minus 210 ft

#22. If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, you may have been

Operating with higher-than-normal oil pressure

Using fuel that has a higher-than-specified fuel rating

Operating with too much power and with the mixture set too lean

Operating with the mixture set too rich

#23. You are carrying out a magneto check as part of the engine checks prior to take-off. When you switch from BOTH to LEFT and back to BOTH, there is no drop in rpm. You switch from BOTH to RIGHT and back to BOTH and note an rpm drop of 100

The aircraft is serviceable to fly because the drop in rpm on both magnetos is within limits

The aircraft is serviceable to fly, but the fact that there was no drop when LEFT was selected should be reported after landing

You should carry out a ‘dead cut’ check in these circumstances

The aircraft should not be flown, since not be flown, since no rpm drop on one magneto may indicate a fault

#24. Which of the following is not a type of Drag?

Induced Drag

Type Drag

Parasite Drag

Interference Drag

#25. The presence of carburetor ice, in an airplane equipped with a fixed pitch propeller, can be verified by applying carburetor heat and noting

A decrease in RPM and then a gradual increase in RPM

A decrease in RPM and then a constant RPM indication

An immediate increase in RPM with no further change in RPM

An increase in RPM and then a gradual decrease in RPM
