In the event of an electrical fire during flight, which action is NOT required?

• A. Turn off the master switch
• B. Activate the fire extinguisher
• C. Close vents, cabin air, and heat
• D. Keep all switches on

Answer: (D)

When an electrical fire occurs during flight, it's crucial to take immediate and decisive actions to mitigate the danger. Keeping all switches on is not required and is, in fact, highly dangerous in this scenario. The reason for this is that turning off all electrical equipment helps to eliminate the source of the fire and prevents further complications that could arise from an electrical malfunction. Switching off the master switch is necessary to cut off electrical power to the circuits, while activating the fire extinguisher and closing vents and cabin air helps to contain and extinguish the fire, as well as prevent the spread of smoke into the cockpit. In summary, maintaining all switches in the on position during an electrical fire is contradictory to the procedures designed to ensure the safety of both the pilot and the aircraft, making it the action that is not required.
