In what position is the constant-speed propeller control placed to check the magnetos?
- Full decrease, low propeller blade pitch angle.
- Full increase, low propeller blade pitch angle.
- Full increase, high propeller blade pitch angle.
what are magnetos?
A rotating propeller imparts rearwards motion to a
- small mass of air at high velocity.
- large mass of air at low velocity.
- small mass of air at low velocity.
i dont understand
The purpose of using reverse pitch propellers is to
- provide aerodynamic breaking.
- allow aircraft to taxi backwards.
- reverse the direction of rotation of the propeller.
isnt the B also right?
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.
Charles' Law states that
- volume varies inversely with temperature.
- volume varies directly with temperature.
- volume equals pressure * temperature.
I think it is wrong,because the formula for charles is V1/T1=V2/T2 which means that volume with temperature are inversely proportional.
