Aircraft Tech

#1. You line up for take off on runway 25. The compass settles to indicate a heading of 210°. The most likely cause is

The deviation card is wrong

Metallic or magnetic objects have been placed near the compass

Turning error which was induced by the turn onto the runway heading

The directional gyro indicator needs to be re-synchronized

#2. If you have a flat battery

Your engine will stop

Your engine will continue to run normally

Your magnetos will become inoperative

Your masters will turn off

#3. The initial reaction to a spin recovery is?

Ailerons – Neutralise the ailerons

Elevator – once the rotation stops ease forward to unstall the aircraft

Power – Close the throttle

Rudder – Apply full opposite rudder

#4. 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

#5. What would the most common indication of a voltage regulator failure be?

Explosion in the engine bay

High or erratic voltage

Flickering of the aircrafts lights

Complete shut down of the electrical system

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

Enables the engine to run hotter

Reduces pre ignition

Reduces detonation

Efficiency and redundancy

#7. What is adverse yaw?

Incorrect use of rudder trim

Secondary effect of roll

Tendency of the aircraft to yaw out of the turn

Having a centre of gravity too far AFT

#8. What is parasite drag?

Drag caused by converging airflows

Drag caused by the frontal surface area

Drag caused by creating lift

Drag caused by non lift producing surfaces

#9. Flying at altitude around clouds you notice a gradual decrease in RPM, what would be your initial action, and what would be the initial result?

Apply a leaner mixture, RPM will increase

Apply carb heat, RPM will increase

Apply carb heat, RPM will decrease

Increase power, RPM will increase

#10. To prevent condensation forming in the fuel tanks when the aircraft is to be parked overnight (or not to be used for several days), it is good practice to..

Fill the fuel tanks

Drain the fuel tanks

Leave the tanks partially full

Use a higher grade of fuel

#11. 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

#12. An aircraft flying a standard ‘rate 1’ turn, will turn through 270° in:

1 minute and 45 seconds

90 seconds

2 minutes

45 seconds

#13. While maintaining straight and level flight, if you were to increase airspeed you would have to?

Lower the nose

Raise the nose

Lower flaps

Lean the mixture

#14. What would indicate a failure in the pitot static system?

The DI will indicate a false reading

The VSI will indicate a false reading

The ASI will indicate a false reading

The Altimeter will indicate a false reading

#15. Define aspect ratio and the correct example

Span / Chord and a Cherokee is an example of a high aspect ratio

Chord / Span and a Cherokee is an example of a low aspect ratio

Span / Chord and a Glider is an example of a high aspect ratio

Chord / Span and a Glider is an example of a low aspect ratio

#16. 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

#17. 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

#18. The force pulling the aircraft into the turn is?

Centripetal force

Centrifugal force

Loading

Lift

#19. 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

#20. After start up, you carry out a live cut check, this is to?

Check if the magnetos are isolating when the key is switched to the “off” position

Check for plug fouling

Check the starter has disengaged

Check the impulse coupling has disengaged

#21. What instruments use the static vent(s)?

Altimeter, Vertical speed indicator, Airspeed indicator

Altimeter, Artificial horizon, Vertical speed indicator, Airspeed indicator

Altimeter, Directional indicator, Vertical speed indicator, Airspeed indicator

Altimeter, Directional indicator, Airspeed indicator

#22. An aircraft is being flown in a glide at the recommended gliding speed. The glide distance over the ground will be increased by

Increasing the speed

Decreasing the speed

Holding a higher nose attitude

A tailwind

#23. 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

#24. 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

#25. 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
