Term
 How many batteries power the airplane?
Definition
 Two
Term
 What type are they?
Definition
 What type are they?
Term
 Where are they located?
Definition
 #1 in the nose; #2 behind rt. wing root.
Term
 How many volts and amps for each?
Definition
 24VDC; 34 Ah, 36 Ah
Term
 Which battery provides electrical power for engine starting?
Definition
 #2 battery
Term
 What is the minimum voltage for starting?Charging?
Definition
 24 volts27 volts
Term
 How many generators?Volts?Amps?
Definition
 Two28 VDC400 amps
Term
Definition
 Ground=330A In-Flight=390A
Term
 What is the minimum battery temperature for normal operation?
Definition
 -10C (14F)
Term
 What function in the electrical system allows the engine to start withoutcausing surges in the Avionics?
Definition
 Quiet Start Contactor.
Term
 If a single generator fails in-flight, what happens?
Definition
 Both SHED BUSES lose power.
Term
 What does it mean if the GPU is plugged in, but there is no GPU AVAIL lightilluminated on the button?
Definition
 DC power requirement from the GPU of between 26V and 29V is not being met.
Term
 What are we looking for when we push in the Electrical Emergency Button onthe before taxi checklist?
Definition
 That the batteries show at least 23.5 volts.(The generators continue to power the DC busses in this scenario, but certainother relays open in order to confirm battery voltage).
Term
 If the GPU is powering the airplane, when do the generators come on line?
Definition
 When the GPU is disconnected (from the Central Bus) which can be confirmed onthe electrical synoptic page.
Term
 If the GPU is connected and the Electrical Emergency Button is pushed in, whathappens?
Definition
 Because the generators are not on-line yet, the electrical system is forced intoelectrical emergency, connecting the batteries directly to the emergency buss.(The GLC 1, GLC 2, SBC 1 and SBC 2 will be commanded to open, and BTC 1 andBTC 2 will be hardwire locked out, EBC 1 will open and EBC 2 will close).The Batteries 1 and 2 will supply power to the HOT BATT BUSES, EMERGENCY BUSand the CENTRAL BUS.
Term
 If a Dual Generator failure occurs in flight, what remains powered?The aircraft wiring logic will automatically configure the electrical emergencyscenario. The Batteries 1 and 2 will supply power to the HOT BATT BUSES,EMERGENCY BUS and the CENTRAL BUS providing engine starting.
Definition
 The aircraft wiring logic will automatically configure the electrical emergencyscenario. The Batteries 1 and 2 will supply power to the HOT BATT BUSES,EMERGENCY BUS and the CENTRAL BUS providing engine starting.45 minutes max.
Term
 If while in flight, the CAS message ELEC XFR FAIL appears, what is thememory item and why is this procedure necessary?
Definition
 ELEC EMER BUTTON…………PUSH INA complete in-flight loss of the main generating system has occurred, but theautomatic transfer logic has failed to configure the electrical emergency condition,so pushing in the button allows the pilot to override the automatic transfer failureand enable the load shedding process by forcing the system into the electricalemergency condition.
