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. |

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. |
