22 - Instrument and Electrics Samples

Note:  The correct answer under (a) during the exam order answers will be different. 

Q.1. Regarding Ohm's law:.

    a- The current in a circuit is directly proportional to voltage.
    b-The current in a circuit is directly proportional to the resistance of the circuit.
    c- The power in the circuit is inversely proportional to the square of the current..
    d- The current in a circuit is inversely proportional to voltage.
Q.2. The auxiliary power unit (APU) has its own AC generator that:
    a- Supplies the aircraft with three-phase 115 V, 400 Hz AC.
    b- Is driven at constant speed through a constant speed drive (CSD), in the same way as the main AC generator.
    c- Is excited by its generator control unit (GCU) as soon as the APU starts up.
    d- Must have the same characteristics as the main AC generator so that it can be easily coupled with the latter.
 Q.3. An autopilot system:
    a-  Must provide at least aircraft stabilisation functions.
    b-  Must provide at least aircraft guidance functions. 
    c-  Must provide automatic take off functions..
    d-  May provide automatic take off functions.

 Q.4. The aural alert(s) associated with the mode 4 (unsafe terrain clearance) of the GPWS is (are): 

1 - "TOO LOW GEAR " 

2 - "TOO LOW TERRAIN "

3 - "TOO LOW FLAPS"

4 - "PULL UP"

The combination that regroups all of the correct statements is:

    a-  1, 2 and 3.
    b-  1, 2. 
    c- 2.
    d-  2, 4.
