1 - In a steep turn to the left, when using spoilers ...
The Right Aileron Will Descend, The Left One Will Ascend, The Right Spoiler Will Extend And The Left One Will Retract.
The right aileron will descend, the left one will ascend, the right spoiler will retract and the left One will extend.
The Right Aileron Will Ascend, The Left One Will Descend, The Right Spoiler Will Retract And The Left One Will Extend.
The Right Aileron Will Ascend, The Left One Will Descend, The Right Spoiler Will Extend And The Left One Will Retract.
2 - Cabin differential pressure means the pressure difference between:
Cabin Pressure And Ambient Air Pressure At Msl.
Cabin pressure and ambient air pressure.
Flight deck and passenger cabin.
Actual Cabin Pressure And Selected Pressure.
3 - About a twin spool compressor:
The Low Pressure Spool Runs At A Very High Rpm, Thus Preventing The Onset Of Compressor Stall.
Both spools run at the same RPM.
The low pressure spool runs at a lower RPM than the high pressure spool.
When Operating At Very High Rpms, The Later Stages Within The High Pressure Spool Will Have A Large Negative Angle Of Attack.
4 - Control surface flutter can be avoided by:1. a high torsional stiffness of the structure.2. a low torsional stiffness of the structure.3. locating a balancing mass in front of the control hinge.4. locating a balancing mass behind the control hinge.The combination that regroups all of the correct statements is:
2, 4.
1, 4.
1, 3.
2, 3.
5 - An engine pressure ratio (EPR) can be defined as the ratio of:
Jet Pipe Total Pressure To Combustion Chamber Pressure.
Combustion chamber pressure to compressor inlet total pressure.
Jet pipe total pressure to compressor inlet total pressure.
Compressor Outlet Pressure To Compressor Inlet Total Pressure.
6 - A tubeless tyre has: 1- a built-in-air tube. 2- no built-in-air tube. 3- a crossed side casing. 4- a radial side casing The combination of correct statements is:
2, 4.
1,3.
2, 3.
1, 4.
7 - A static inverter is a:
Static Discharger.
Device for reversing the polarity of the static charge.
Filter against radio interference.
Transistorized unit used to convert dc into ac.
8 - When excessively leaning the mixture for a better fuel economy, but still on the rich side of the peak EGT, the following engine parameter(s) may exceed their normal operating ranges:
Oil Temperature.
Engine RPM.
Manifold pressure.
Cylinder head and exhaust gas temperature.
9 - In jet aeroplanes the 'thermal anti-ice system' is primarily supplied by
Turbo Compressors.
Bleed air from the engines.
The APU.
Ram Air, Heated Via A Heat Exchanger.
10 - The advantage of mounting the tailplane on top of the vertical stabilizer (a "T-tail" configuration) is:
To Have Greater Effectiveness At High Speed.
To decrease fuel consumption by creating a tail heavy situation.
That it does not require a de-icing system.
To withdraw it from the influence of wing turbulence.
