11. Which of these statements is false?
pg36- Aa) The pressurized air from the engine is enough for power pneumatic systems.
- Bb) At ground APUs (Auxiliary Power Units) are used to provide pressurized air and electricity.
- Cc) Jet engines use bleed air from compressor.
- Dd) Reciprocating engines use bleed air from the turbocharger.
22. Has gas turbine pressure dependence on the shaft speed?
pg36- Aa) Yes, it has a strong dependence.
- Bb) No, gas turbine pressure depends on the compression ratio of the compressor.
- Cc) a) and there must exist an engine bleed air control system.
- Dd) b) apart from the compression ratio it depends on the outside temperature too.
33. The types of engine bleed systems are:
- Aa) Intermediate and High pressure mixed systems.
- Bb) Low and High pressure mixed system.
- Cc) High isolated pressure system.
- Dd) a) and b) are true.
44. Wich of these statements is true?
- Aa) The pneumatic power has no return line
- Bb) There’re no leakages and it’s easy to handle high pressures.
- Cc) It’s the most common system to operate landing gears.
- Dd) The pneumatic power systems need more tubing and valves than hydraulic systems.
55. The pneumatic systems are usually used to:
ph36- Aa) Operate landing gears
- Bb) Move alerions.
- Cc) Pressurize hydraulics reservoirs.
- Dd) Operate the brakes.
66. Pneumatic systems in Harrier aircrafts are used to:
pg36- Aa) Operate the landing gear
- Bb) Increase the speed during a conventional take off.
- Cc) Give roll and pitch stability
- Dd) Reduce the speed during a conventional landing.
77. Why does not the civil VTOL like the wing tips with pneumatic air to provide stability?
pg36- Aa) Esthetically it’s not attractive.
- Bb) They harm the aerodynamic.
- Cc) They are not effective.
- Dd) Because if the compressor fails, the aircraft lose the roll and pitch stability.
88. The air bleed system provides air to:
pg37- Aa) Pressurisation system

124. Which is the disadvantage of float level sensor:
- Aa) It is expensive.
- Bb) The float arm may stick or jam.
- Cc) It is difficult to build.
- Dd) The materials are too heavy.
135. If an emergency or malfunction after takeoff happens:
