The function of a propeller pitch lock is to prevent the propeller from
- coarsening.
- reducing below flight fine pitch.
- fining off in the event of pitch lock mechanism failure.
i found an answer :leaflets refer to a pitch lock that holds the fine pitch stop in position, but also adds that some
manufacturers have a pitch lock device that locks the prop in its last position in the event of failure of the pitch lock
mechanism. For a description of this system see Jeppesen Aircraft Propellers and Controls page 136.
When the compressive force on a speeder spring is reduced, the propeller blades will
- remain fixed.
- fine off.
- coarsen.
why? if i reduce the speeder sreeng pressure the fly weight close and the pitc become finner
When governor spring load is less than governor weights, the CSU is in
- overspeed.
- underspeed.
- normal.
how? i dont get it
The purpose of the pitch change cams is to
- convert rotary motion to linear motion.
- prevent windmilling.
- convert linear motion to rotary motion.
is it not for changing rotary to linear?
How is the efficiency of a turbo prop engine assessed?
- By correcting propeller RPM for ambient Air temperature and barometric pressure.
- By comparing compressor and propeller RPM against a reference figure.
- By comparing torque meter pressure against a reference figure.

On a Hartzell prop with counterweights, full oil supply would indicate
- on-speed condition.
- overspeed condition.
- underspeed condition.
why?
To fit a new front cone to a prop shaft firstly
- etch the propeller serial number to the rear face.
- cut in half with a hacksaw and etch a unique serial number to both halves.
- coat in Engineers blue to ensure seating in the propeller front boss.
this is wrong answer pls check CAIP for correct ans.
option 3 is correct which is coat in Engineers blue to ensure seating in the propeller front boss.
On an electrical deicing system fast cycle is used
- at low air temperature.
- at high air temperature.
- on the ground.
Why would de-icing be used in high air temperature?
If the tip of an electrical overshoe is torn
- it may be cut back.
- it may be classified as acceptable damage.
- it must not be cut back.
can someone explain this, i dont get what the question means by "cut back"
What is the principle of an O2 generator?
- Sodium chlorate and iron mixed by an electronic detonator.
- Sodium chlorate and iron using a mechanical detonator producing O2 when mixed with air.
- Sodium chloride and iron mixed by an electronic detonator.
iron mixed by an electronic detonator or iron using a mechanical detonator?!
refer to CAIPs AL/3-25 3.5.1

- 0.0001 per degrees C.
- 0.0101 per degrees C.
i dont understand it
