Last set of 7 questions. Can somebody help me to see whether have I chosen the correct answer? Thank you.
Q10. Appropriate use of carburettor heat:
(a) (OFF) Cold on finals
(b) (OFF) Cold on glide descent without power
(c) (ON) Hot on take off
(d) (ON) Hot in cruise
Q11. Aircraft reverse thrust
(a) only exist in turboprop engine since the turbojet engine does not have the mechanism
to change the direction of the exhaust efflux
(b) aid braking and direction control on ground
(c) used for noise attenuation by reducing the velocity of exhaust efflux
(d) is done by reverse the angle of the turbine blades in turbojet
Not sure is it correct? I chose (b)
Q12. What is the ultimate limitation of the engine for supercharging?
(a) Turbine RPM
(b) Exhaust Gas Temperature
(c) Compressor RPM
(d) Intake Temperature
Q13. Limitation of superchargers:
(a) continue to run without cooling
(b) increase speed without cooling
(c) high temp due to compression
(d) running one at a time
Q14. Entrance to combustion chamber:
(a) continue to run without cooling
(b) increase speed without cooling
(c) airflow slowed down to prevent flameout
(d) running one at a time
Not sure is it correct? I chose (b)
Q16. If engine power is increased with propeller lever in the constant speed range, rpm increase, then:
(a) Governor weights move out, blade angle decrease, rpm decrease, weights remain
(b) Governor weights move in, blade angle increase, rpm decrease, weights move out
(c) Governor weights move out, blade angle increase, rpm decrease, weights move in
(d) Governor weights move out, blade angle increase, rpm decrease, weights move in, blade angle decrease again
Not sure is it correct? I chose (c)
Q17. When the plane goes into descent without increasing power with RPM, airspeed increases, what does the CSU do to maintain constant RPM
(a) increase the blade angle
(b) to remain covered by fuel irrespective of the aircraft attitude
(c) decrease the blade angle
(d) maintain blade angle
