1 - The type of gate which requires all conditions with logic 1 for engagement is: Or. NAN A C. And.nor.

2 - In case of engine failure during flight the blades of a constant speed propeller in a single engine aeroplane, not fitted with feathering system Move In Low Pitch Position By Oil Pressure Created By The Windmilling Propeller. Move in the lowest pitch position by the centrifugal force and/or the spring force . Move in the highest pitch position by the aerodynamic force. Move In A Certain Pitch Position Depending On Windmilling Rpm.

3 - The modern anti-skid processes are based on the use of a computer whose input data is: 1. idle wheel speed (measured)2. braked wheel speed (measured)3. brake temperature (measured)4. desired idle wheel train slipping rate5. tire pressur The combination regrouping all the correct statements is: 1, 2, 4. 1, 3. 2, 4. 1, 2, 3, 4, 5.

4 - Oxygen systems are systems used on pressurized airplanes in 1. an emergency in the case of depressurization. 2. an emergency in the case of the indisposition of a passenger. 3. normal use in order to supply oxygen to the cabin. 4. an emergency in the case of smoke or toxic gases The combination regrouping all the correct statements is: 1, 2, 2004 3 1,4 2, 3

5 - Engine compartment decking and firewalls are manufactured from: Stainless steel or titanium sheet. Asbestos blankets. Composite materials such as carbon, kevlar and fibre glass. Aluminium Alloy Sheet.

6 - The purpose of the 'Pressure Relief Valve' in a high pressure oxygen system is to: Reduce Pressure In The Oxygen Reservoir To A Suitable Manifold Pressure For The Regulator Act as a manual shut-off valve Relieve overpressure if the pressure reducing valve malfunctions Maximize The Charging Pressure Of The System

7 - A reverse thrust door warning light on the flight deck instrument panel illuminates when: The reverser doors are unlocked. The reverser doors have moved to the reverse thrust position. Reverse has been selected but the doors have remained locked. The Reverser Doors Are Locked.

8 - A single action actuator: Travels One Direction Under One Application Of Hydraulic Power And In The Opposite Direction Under A Second Application Of Hydraulic Power. Cannot be used for variable position operations as it is designed to lock in the extremities of travel. Is powered in one direction only by hydraulic power, the return movement being under spring force. Is A One Shot Actuator Used For Emergency Systems Only.

9 - The essential difference between aircraft AC alternators and DC generators (dynamos) is that the: Alternators Supply All Of The Output Current Through The Commutators And Brush Assemblies. Induced windings of the alternators are rotating (rotor), and the dynamos have a rotary inductor coil. The alternators generate much less power than DC generators. Induced (output) windings of the alternators are fixed (stator), and the dynamos have a fixed Inductor (field) coil.

10 - 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.
