Engine Fire In Flight
Gulfstream G450 Abnormals
The CAS may or may not appear, along with any of the following:
Engine fire loop senses a fire. If the lights in the FIRE handle and FUEL CONTROL switch are illuminated, the fire warning is valid. If the lights are not illuminated, you may have a faulty fire detection loop.

In the event an engine fire warning is annunciated, proceed as follows:
NOTE: The pilots shall agree on the correct (affected) FUEL CONTROL switch prior to placing it in the OFF position, as well as the correct FIRE HANDLE prior to actuating it.
NOTE: When it is necessary to discharge a fire bottle, ALWAYS use DISCH 1 first.
If fire warning indications are no longer present:
If fire test / fire detection test is satisfactory, proceed to Step 9. If fire test / fire detection test is not satisfactory or fire warning indications persist for thirty (30) seconds:
If fire test / fire detection test is satisfactory, or after discharge of fire bottle(s):
NOTE: Match FGC to operating engine: FGC 1 = Left Engine; FGC 2 = Right Engine.
NOTE: See Fuel Load Balancing, page EE-23.
One Engine Inoperative Landing Procedure:
NOTE: For approach and landing, operation of landing gear, flaps, spoilers, reverser, and brakes should be accomplished as separate events, not simultaneously.
At Final Approach Fix:
NOTE: If electing to land at flaps 20°, fly the approach at VREF for flaps 20° +10 knots and select the GPWS GND/SPLR Flap ORIDE to ON. See AFM Section 5, Performance, for landing distance in the flaps 20° configuration.
NOTE: If strong winds are present, add to VREF ½ of the steady state wind plus the full gust to maximum additive of 20 knots.
