ELECTRICOS

A good battery should supply power to the hot battery bus and the emergency bus for approximately:

• 2 hours

• 1 hour

• 30 minutes

• 10 minutes

The battery bus serves as:

• A power-off DC source

• An emergency power source

• An extension bus

• A generator tie bus

In flight, with generators on line; the battery is isolated from any charging source when the battery switch is in:

• A.OFF

• B. BATT

• C. EMER

• D.Both A and C

  If manual termination of a start sequence is desired, the switch to press is:

• ENGINE START

• STARTER DISENGAGE

• LH START

• RH START

The voltage read on the voltmeter with the selector switch in BATT is sensed from the:

• Battery bus

• Left main bus

• Hot battery bus

• Right main bus

If the generators are not operating, the voltmeter reads battery voltage when the battery switch is in:

• A.OFF

• B.BATT

• C.EMER

• D.Both B and C

The light in each engine start button illuminates to indicate:

• Starting is complete.

• Opening of the start relay

• Closing of the start relay

• Generator disconnect

If a battery start is intended, the GEN switches should be placed to:

• OFF

• GEN

• RESET

• ON
