The generator will be disconnected from the buses in the event of a high voltage or reverse current situation. This means that if the voltage exceeds a certain threshold or if there is a flow of current in the opposite direction, the generator will be disconnected from the buses. This is done to protect the generator and the buses from any potential damage that could occur in such situations.
14.
How is the starter/generator cooled?
Correct Answer
D. A and B
Explanation
The starter/generator is cooled by an integral fan and a blast tube above the oil cooler, in the air inlet on the right forward cowling. These two methods work together to ensure that the starter/generator does not overheat during operation. The integral fan helps to circulate air and dissipate heat, while the blast tube directs cool air from the air inlet on the cowling towards the starter/generator. This combination of cooling mechanisms ensures efficient and effective cooling for the starter/generator.

24.
If a CB pops after how many minutes will you reset that CB(at the engine/inside the cockpit)?(As per the flight safety manual page 2-15)
Correct Answer
C. 3
Explanation
According to the flight safety manual, if a circuit breaker (CB) pops, it should be reset after 3 minutes. This time interval allows for the CB to cool down and reset itself before attempting to restore power. Resetting the CB too soon could potentially cause damage or a repeated pop. Therefore, waiting for 3 minutes is the recommended procedure for resetting a CB after it pops.
25.
Below what Voltage will the standby electrical system (Alternator) supply power to the system?

When the stanby power goes ON during flight(Gene goes offline). What will your initial actions be to maintain comms/avionics(After tripping and reseting the Generator)?
Correct Answer
C. Switch On “avionics stanby power” and “avionics bus tie”
Explanation
When the standby power goes ON during flight and the generator is tripped and reset, the initial action to maintain comms/avionics would be to switch on both the "avionics standby power" and the "avionics bus tie." This is because the standby power alone may not be enough to power the avionics system, and the bus tie is necessary to connect the standby power to the avionics system. Therefore, both switches need to be turned on to ensure the avionics system continues to receive power and maintain communication.
27.
How do you check the standby electrical system?(As per the POH)
Correct Answer
C. A and B
Explanation
To check the standby electrical system as per the POH, you need to perform two steps. First, you need to "trip" the generator. Second, you need to select the knob to "ALT" and observe a 1 volt drop between "GEN" and "ALT". Both steps A and B are necessary to properly check the standby electrical system.
28.
When should the strobe light be used(strictly speaking)? (As per the flight safety manual)
Correct Answer
A. At night
Explanation
According to the flight safety manual, the strobe light should be used strictly at night. This means that it is not recommended to use the strobe light during the day. Strobe lights are typically used on aircraft to increase visibility and alert other pilots or ground personnel of their presence. However, during daylight hours, other lighting systems such as navigation lights and landing lights are usually sufficient for visibility purposes. Therefore, the strobe light is specifically designated for nighttime operations to enhance safety and prevent confusion or distractions during daylight hours.
29.
When is it not recommended to use the strobe light?
Correct Answer
E. All of the above
Explanation
The strobe light is not recommended to be used in any of the given conditions: on the ground, in fog, in haze, and in precipitation. This is because these conditions can affect visibility and make it difficult for other pilots or vehicles to see the strobe light, increasing the risk of accidents or confusion. Therefore, it is best to avoid using the strobe light in these situations.
