What assists the pilot in identifying and separating electrical circuit breakers on the
overhead console? - correct answer 1. Separation of No.1 & No.2 buses and system
circuit breakers
2. Bracketing circuit breakers under main headings
3. Marking bus dependency
What is the purpose of the EMERG LOAD switch? (SN33108 and subsequent) - correct
answer Load shedding in the event of an dual generator failure
What is displayed on the DC Voltmeters? - correct answer No.1 & No.2 essential DC bus
voltage
,What does the dual ammeter indicate? - correct answer Amperage load on each
generator
When will the nonessential bus be automatically powered? - correct answer Only
when both generators are on line
When starting both engines using external power, which Battery Bus switches must be
on? - correct answer Both... the No.1 & No.2 Battery Bus switches
