Turbine engine fire zones are designated to focus protection on the hot, critical core of the engine. In practice, the only fire zone recognized for turbine engines is the engine power section, which includes the core components that produce thrust and the area most at risk from fire. This is the part where fire detection and suppression are concentrated, so there isn’t a separate fire-zone designation for the compressor or the accessory sections. The avionics bay and the wing leading edge aren’t turbine engine fire zones—they’re other parts of the aircraft. So stating that the engine power section is the sole fire zone designation for turbine engines matches how these fire-protection zones are used.
