An illuminated red WHEEL WELL Fire Warning Light indicates ________. a fire in the main gear wheel and/or a fire in the nose wheel well a fire in the main gear wheel and/or a fire in the nose wheel well, and arms the squib a fire in the main gear wheel well.
What does an illuminated engine BOTTLE DISCHARGE light indicate? the related fire extinguisher bottle has been armed and is ready for discharge the related fire extinguisher bottle has discharged there is a fault in the fire protection system and the bottle cannot be discharged.
What does an illuminated APU DET INOP light indicate? The APU bleed air is inoperative The APU door failed to close during shutdown, and a fire test cannot be performed APU detector loop has failed.
What does an illuminated APU BOTTLE DISCHARGE light indicate? there is a fault in the fire protection system and the bottle cannot be discharged the APU extinguisher bottle has been armed and is ready for discharge the APU extinguisher bottle has discharged.
Does pushing the Master Fire Warning (FIRE WARN BELL CUTOUT) on the glareshield have the same results as pushing the fire warning bell cutout switch on the overheat/fire protection panel? True / Yes False / No.
