Which turbine engine installation fire-zone designation is explicitly listed?

• A. The compressor and accessory sections of turbine engines
• B. The engine power section
• C. The avionics bay
• D. The wing leading edge

Answer: (A)

The concept here is how turbine engine installations are divided into fire zones for protection and suppression. In standard turbine engine installation documentation, the fire-zone designation that is explicitly listed is the compressor and accessory sections of the turbine engine. This area is identified as a distinct fire zone because it houses critical components like the compressor, accessory gear train, fuel controls, and oil systems, where a fire could originate or quickly spread and thus requires dedicated detection and protection. The engine power section, avionics bay, and wing leading edge are not the explicitly listed turbine engine fire zones in this context. The power section is part of the engine core, but it isn’t specified as a separate fire-zone designation in the typical installation listings, and the avionics bay and wing leading edge are not engine-related fire zones.
