Cabin Crew Fire Training
Currently cabin crew are trained to handle fires inside the cabin. This training should be expanded to cover checking for airframe and engine fires after a reject or landing with engine problems - along with proactive communication of fire status with the flight crew.
They need to be able to distinguish between tire/wheel/brake fires where three minutes is allowed before ARFF arrives - and uncontrolled fuel fed fires demanding immediate evacuation.
Given that interphone calls may not be answered in a high cockpit workload situation, cabin crew need to be able to actuate an "EVACUATE" alarm that would annunciate in the cockpit and display prominently on the EFIS.
It may also be useful to have a "Fire / Smoke Visible" annunciation so that the cockpit crew will be prepared in the case that the cabin crew determines evacuation is necessary.
Underlying these suggestions is considerable history of cockpit crews running checklists while unaware of a serious fire behind.
