An APU fire is indicated on which panels?

An APU (Auxiliary Power Unit) fire indication is primarily monitored on specific panels that provide crucial information regarding the APU's status and related systems. The APU control panel contains the relevant switches and indicators that are essential for monitoring the operational condition of the APU, including any fire indications. The aft left loadmaster panel is included as it may also provide visual warnings or alerts about the APU’s health and any related incidents, including fires. Additionally, the single point refueling panel is relevant because it pertains to fuel systems where a fire may originate; thus, it is a key point of reference for fire indications relating to the APU.

These panels collectively ensure that the flight crew is alerted to any APU fire incidents promptly and can take appropriate action. Monitoring these areas is vital for safety and effective emergency response during operations.
