Electrical RKA Questions Flashcards
What type of electrical system is the airplane equipped with?
28V DC Electrical Power, Generation and Distribution System (AOM 9-05-01)
If both generators are available, do they operate in a split bus mode or parallel mode?
• Split bus mode (AOM 9-05-01)
What does the white AVAIL light indicate?
- That the GPU button is pushed in
- A GPU is connected
- The voltage is set between 25V DC -30V DC
(AOM 9-05-30)
Which light will illuminate when the GPU button is pushed in and providing power to the airplane?
• The green IN USE light (AOM 9-05-30)
If the APU is started while the airplane is being powered by the GPU, which one will be the source of electrical power for the airplane?
• The APU
(AOM 9-05-30)
What color does the battery voltage indication show if the battery is discharging?
• Amber (AOM 9-05-30)
What will the indication be on the electrical synoptic page if the GPU is connected but is not providing power to the airplane?
• A white GPU (AOM 9-05-30)
Will the Ram Air Turbine (RAT) be continuously displayed on the electrical synoptic page? If not, when will it be displayed?
• No, when it is deployed and providing power to the airplane
(AOM 9-05-30)
How can a pilot manually command the RAT to deploy?
• The right seat pilot can pull the RAT manual deploy control (AOM 9-05-30)
What are the main engine generators and the APU generators rated at?
• 28V DC, 600 A maximum continuous output (AOM 9-05-40)
What is the minimum GPU voltage required to start charging the batteries?
• 28V DC (AOM 9-05-40)
What buses is the APU capable of supplying power to on the ground if the APU is the only source of electrical power?
• All electrical loads, including the SHED BUSES and charging the batteries
(AOM 9-05-40)
What buses are the APU capable of supplying power to in flight?
• All electrical loads, (except for the SHED BUSES) and charging the batteries
(AOM 9-05-40)
What buses does the RAT generator power?
EMER BUS 1, EMER BUS 2 and EMER BUS 3, as well as providing battery charge current (AOM 9-05-40)
When will the RAT automatically deploy?
• During an electrical emergency (AOM 9-05-40)
