Why are most aircraft systems DC powered when the aircraft produces AC power? - ✔✔AC power is
more efficient to produce because of lighter and smaller components, but batteries only use DC. In an
emergency with only battery power available systems must utilize DC power in order to function. DC
power often is more efficient to transmit because of lower voltages.
How many batteries does the aircraft have? - ✔✔Two nickel-cadmium batteries rated at 43amps for the
APU battery and 17amps for the Main battery
What controls DC power distribution? - ✔✔Two DCPC's
Which busses are hot busses? - ✔✔Main battery direct bus, APU battery direct bus, and the emergency
bus
What does it mean when a bus is hot? - ✔✔It is always powered, regardless of aircraft state.
Why is the DC service switch on the terminating checklist? - ✔✔It is powered by the DC service bus from
the APU battery direct bus and thus is hot, so if left on after powering down the plane you run the risk of
killing the battery. Nice job putz.
