1 - Define the term "FATIGUE":
If a material is continually loaded and unloaded it will eventually break even though the load Remains the same.
The material suffers progressively more permanent damage each time that it is loaded and unloaded.
A loading on the material but it returns fully to its former state when the load is removed.
A One Off Loading That Breaks The Material.
2 - The crash/fire axe is part of the safety equipment fitted to passenger aircraft. Its function is to
Activate A Radio Survival Beacon By Cutting Off The Red Coloured Top
Free exits in case of evacuation via the sides.
Settle an escalating conflict with unreasonable passengers, who threaten flight safety.
Obtain forced access to a fire behind a panel and a general purpose tool during evacuation.
3 - An AC generator driven by a CSD unit:
Does Not Need A Voltage Controller Since The Csd Will Ensure Constant Voltage.
Requires a voltage controller to maintain constant voltage under load.
Requires a voltage controller to maintain constant frequency.
Does Not Need A Voltage Controller Since An Ac Generator Voltage Cannot Alter Under Load.
4 - 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.
5 - In large modern aircraft, in the air conditioning system, reduction of air temperature and pressure is achieved by:
An expansion turbine.
6 - The fuel temperature, at which, under standard conditions, the vapour ignites in contact with a flame and extinguishes immediately, is the:
Self ignition point
7 - Hydraulic fluids must have the following characteristics 1. thermal stability 2. low emulsifying characteristics 3. corrosion resistant 4. good resistance to combustion 5. high compressibility 6. high volatility 7. high viscosity The combination regrouping all the correct statements is:
2, 3, 4, 5
1, 2, 5, 7
1, 3, 4, 6
1, 2, 3, 4
8 - 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.
9 - The main purpose of a constant speed drive unit is to:
Take Part In The Balancing Of Reactive Loads.
Mechanically protect the alternator drive shaft during coupling.
Maintain a constant frequency.
Take Part In The Voltage Regulation.
10 - The ice protection system currently used for the most modern jet aeroplanes is the
Liquid De-icing System.
Pneumatic system with expandable boots.
Electrical de-icing system.
Hot air system.
