If a generator trips, what is the recommended initial action?

• A. Reset the generator switch.
• B. Reset the battery master switch.
• C. Check the cockpit voice recorder.
• D. Initiate a diversion to the nearest suitable airport.

Answer: (A)

When a generator trips, the first action is to reset the generator switch. This reset clears many transient faults or momentary overloads and gives the generator a chance to reclose and re-energize the electrical system. If the generator comes back online, you can continue normal operations while monitoring for any repeated trips.

If it does not return after the reset, you then follow the published abnormal procedures for continued electrical fault, such as shedding nonessential loads and assessing remaining power sources. Resetting the battery master switch isn’t done initially because the goal is to restore the generator’s output first, not to switch to battery power right away. Checking the cockpit voice recorder isn’t part of the flight-time recovery actions for a generator trip, and diverting to an airport is a broader decision made only if the electrical loss degrades safety or prevents continued safe flight.
