The safety of aircraft occupants is the primary
consideration when a fire occurs, therefore, it is
imperative that every effort be made by the flight crew
to put the fire out. On the ground it is essential that
the engines be shut down, crew and passengers
evacuated, and fire fighting begun immediately. If the
aircraft is airborne when a fire occurs, the most
important single action that can be taken by the pilot is
to land safely as soon as possible.
