T6-B Systems 2 (Electrical, Engine, ...)
1. What is the primary source of Generator component of the starter/gen-
aircraft power? erator
2. What voltage and amperage is 28 VDC, 300 amps
the generator rated at?
3. What is the primary purpose of Provide a source of power for starting the
the battery? starter/generator
4. Where is the Generator Control Under the generator circuit breaker pan-
Unit or "GCU" located? el, on the right-hand side, in the aft cock-
pit.
5. What is the function of the GCU? Protects generator from overvoltage/un-
dervoltage, regulates voltage for gener-
ator, and turns off generator in case of
malfunction
6. What is the voltage and amper- 24 VDC, 42 amps
age of the battery?
7. How many sources of electrical 4 sources of electrical power: the
power does the T-6B have, and starter/generator, the battery, the auxil-
what are they? iary battery, and external power
8. What is the voltage and amper- 24 VDC, 5 amps
age of the auxiliary battery?
9. How is the battery charged? Battery is charged by the generator
10. How is the auxiliary battery AuxBat is charged by the battery bus
charged?
11. In the event of generator failure, Approximately 30 minutes of power
how long can the battery provide
power?
12. How can you tell whether the Positive amps indicate battery is being
battery is charging or discharg- charged by the generator, negative amps
ing? indicate the battery is discharging
, T6-B Systems 2 (Electrical, Engine, ...)
13. What are the three most impor- BFI, standby VHF radio, Fire 1
tant components powered by
the auxiliary battery?
14. Where is the auxbat switch lo- In the front cockpit only
cated?
15. How long can the auxbat provide approximately 30 minutes of power (at
power? the same time as the 30 minutes of bat-
tery power, not after)
16. Why can't the battery alone Both the battery and auxbat are rated at
charge the auxiliary battery? 24 VDC
17. What does the red "bat bus" entire battery circuit breaker bus panel
warning indicate? (left panel) may have shorted out
18. What does the red "gen bus" The entire generator circuit breaker bus
warning indicate? panel (right panel) may have shorted out
19. What are the two main electrical Forward cockpit battery bus, forward
busses? cockpit generator bus
20. What does the yellow "bus tie" Indicates that the bus tie is no longer
caution indicate? connecting the battery and generator
busses, they no longer share the same
source of power
21. Where are the exterior lights Front cockpit only, on light/trim panel on
switches located? front left of forward cockpit
22. How are kneeboard lights turned Kneeboard lights comes on when posi-
on and off? tioned downward to a usable position, off
when returned to stowed position
23. When does the landing light illu- only when all 3 gear are down and locked
minate?
