What should be checked alongside Engine Fire Push Switchlights while airborne?

The correct choice concerns the significance of the generator switches in relation to engine fire push switchlights during flight. When an engine fire is indicated by the fire switchlights, pilots must act quickly to determine if the generators are operational, as this affects the aircraft's electrical systems and overall performance. Reliable electrical power is crucial for handling emergency procedures, including potential engine shutdowns and system failures.

Examining generator switches ensures pilots can manage the engine fire scenario effectively, as these systems need to be monitored and potentially shut down to prevent further complications. While the other options such as landing gear position, fuel levels, and wing flaps are vital checks in many situations, they are not directly relevant to the immediate actions taken in response to an engine fire alert. The focus is on managing the electrical systems appropriately to safeguard aircraft operations and crew safety in that critical moment.
