Cabin Fire In Flight
If the cause of the fire is readily apparent and accessible, use the fire
extinguisher to extinguish flames and land as soon as possible.
Opening the vents or doors may feed the fire, but to avoid
incapacitating the crew from smoke inhalation, it may be necessary to
rid cabin of smoke or fire extinguishant. If the cause of fire is not
readily apparent, is electrical, or is not readily accessible, proceed as
follows:
• WARNING •
If the airplane is in IMC conditions, turn ALT 1, ALT 2, and BAT
1 switches OFF. Power from battery 2 will keep the Primary
Flight Display operational for approximately 30 minutes.
