Transfer lift from wings to support the load, and protect passengers/payload

clockwise from behind
|
|

reduce frictionprovide coolingprovides protection
|
|
| 8 |
What provides this lubrication?
|
Engine oil
|
|
| 9 |
What oil system does the pilot need to check?
|
Check oil quantity before each flight
|
|
| 10 |
What type of oil does your engine use?
|
Aero 100, SAE 50
|
|
| 11 |
Why have two magnetos?
|
Incase one fails the other will keep the engine running. Also provides marginal increase in...
|
|
| 12 |
Why fly on both?
|
To prevent engine failure in the case that one magneto fails.
|
|
| 13 |
Why keep the mixture full rich for all circuit operations?
|
Reduce chance of damage when changing power settings
|
|
| 14 |
What if the propeller has dents/chips in the leading edge?
|
Reduce propeller performances and may critically affect strength
|
|
| 15 |
Why does the pilot drain fuel before each flight?
|
To check for impurities, water, and fuel type for safe operation.
|
|
| 16 |
What do you look for when draining fuel?
|
Impurities, water, and fuel colour/type
|
|
| 17 |
When do you use carburettor heat?
|
When you suspect icing and often during decent
|
|
| 18 |
What happens if the pitot cover is left on for take off?
|
The indicated airspeed would be zero, you would not take off.
|
|
| 19 |
What is indicated by the white arc on the ASI?
|
Operating speed range with flaps extended
|
|
| 20 |
How often should you check alignment of the heading indicator? and with what?
|
As soon as in straight and level flight and then every 20 minutes
|
|
| 21 |
What is a canard?
|
the forward wing found on some aircraft
|
|
| 22 |
A pusher has the propeller pushing the air whereas a conventional tractor configuration pulls...
|
Most light aircraft have the tractor/puller propeller
|
|
| 23 |
Explain the riggers angle of incidence?
|
The angle between the fuselage, and a line through the main plane and tail plane
|
|
| 24 |
What is a stabilator?
|
The whole horizontal section of the tail plane moves with pitch control
|
|
| 25 |
What is the main feature of a fowler flap?
|
They move back and down
|
|
| 26 |
What is a chock?
|
Objects placed to prevent the aircraft moving when parked
|
|
| 27 |
What happens to the ignition if the alternator fails?
|
Nothing - ignition and electrical system are independent
|
|
| 28 |
With an RH above 50% and the OAT at 20C, carburettor icing can readily occur _____
|
During any decent
|
|
| 29 |
Carburettor heat is usually used to ____ after the carburettor after ice has formed
|
deice
|
|
| 30 |
What does the carburettor do?
|
Control the quantity of fuel and air that enters the engine
|
|
| 31 |
What does mixture control do?
|
Controls the mixture of fuel and air for best engine performance at different air pressures
|
|
| 32 |
Why have both throttle and the mixture control?
|
Mixture controls fuel/air ratio, throttle controls quantity.
|
|
| 33 |
Why reduce the throttle before the propeller rpm when reducing power?
|
Reducing the throttle first ensures you don't overcharge your engine and cause detonation
|
|
| 34 |
What causes and aircraft with a single propeller to want to veer on take-off?
|
The propeller torque reaction and slipstream effect on the tail. Tailwheels also have the gyroscopic...
|
|
| 35 |
Why does the aircraft's fuel system have a boost pump?
|
Boost pump provides safe backup incase mechanical fuel pump stops
|
|
| 36 |
Which aircraft do or do not have a fuel boost pump?
|
Many high wing planes have gravity fed fuel systems so may not need boost pump
|
|
| 37 |
If the break pedal has no resistance and, when you apply the break, the pedal goes to the floor...
|
Try and stop on the grass to the side of any runways or taxiways
|
|
| 38 |
Explain the difference between pitot, total, static and dynamic pressures?
|
Static pressure = atm pressure outsideDynamic = pressure caused by movement through the airPitot...
|
|
| 39 |
How is air pressure used to indicate airspeed?
|
Use pitot pressure and - static pressure to get dynamic pressure which indicates airspeed
|
|
| 40 |
Why is airspeed not always accurate?
|
Different attitudes mean pitot tube not always in most efficient angle to measure accurately
|
|
| 41 |
How is airspeed used to indicate angle of attack?
|
High angle of attack = slower airspeed
|
|
| 42 |
What does the altimeter read in a climb if the static port is blocked?
|
indicate the altitude at which the blockage occured
|
|
| 43 |
What would the VSI read if the static port was blocked?
|
zero even if climbing or descending
|
|
| 44 |
Why use a vacuum system to drive the gyros?
|
Just so that there is a second source of independent energy to rotate gyros
|
|
| 45 |
Why have electric standby instruments?
|
Electricity is a reliable and independent supply
|
|
| 46 |
Why does the magnetic compass read backwards?
|
The card sometimes oscillates, take your time
