Electrical System and Limitations Flashcards
where is Batt 2?
in the aft right side
which battery does start?
Batt 2
what device protects systems on DC Bus 1 & 2 from surges from Batt 2 during start?
The Quiet Start Contactor (QSC)
battery duration with both generators inop?
45 min. max (“max!”)
what are GPU requirements to power the aircraft?
25V to 29V
where are the LPDU and RPDU located?
in the temperature and pressure controlled rear electronics bay
how long before ITT rise on start? (no light off trigger?)
within 10 seconds
how many power distribution units?
3 - left (LPDU) / right (RPDU) / emergency (EPDU)
where is Batt 1?
in the nose compartment
what is the condition when you have dual gen failure, but auto shed of DC Bus 1 & 2 and Shed Busses doesn’t occur?
an “electric transfer failure” (CAS message ELEC XFR FAIL)
what is operational status of Gen 1 and Gen 2 after starting engines and the GPU is still connected to the system?
Generators are offline. They will remain offline via open GLC 1 and GLC 2 (Generator Line Contactors) close after the GPU power is removed from the system (“unselect” the GPU)
minimum GPU voltage required for battery chargine?
27V
where is the EPDU located?
in the non-controlled nose electronic bay
which busses are powered by Gen 1 during normal ops?
DC Bus 1, Emergency Bus, Hot Bat Bus 1, Shed Bus 1
maximum generator load inflight?
390 Amps each
