FUEGO
Fuego • Detección de sobrecalentamiento en el motor y en ala por medio de censores de alta temperatura. • Extinción de fuego en el motor. • Indicación en el panel anunciador y en el sistema de extinción de fuego. • La prueba del panel anunciador sirve para comprobar la continuidad de todos los censores de motor y ala, al momento de iluminar la luz del panel anunciador y del sistema extinción de fuego.

EMERGENCY PROCEDURE STEADY LIGHT: Indicates brake fire, wheelwell or air conditioning duct overheat *1. BLEED AIR SWITCH (affected side)............................................... OFF 2. LANDING GEAR...................................................................... DOWN Leave gear extended at least three (3) minutes to allow cooling of overheated brakes in order to preclude a brake/tire fire and tire explosion. 3. GENERATOR SWITCH (affected side)........................................... OFF NOTE If the warning light extinguishes, retract the landing gear after three (3) minutes cooling and continue flight with the bleed air OFF; the generator may be RESET/ON. If the light reilluminates STEADY, extend the gear. Expect performance degradation due to the drag of the gear. A diversion and precautionary landing may be necessary. If the light changes to a FLASHING mode complete the wheelwell wing overheat flashing items. CAUTION IF THE WARNING LIGHT DOES NOT EXTINGUISH WITHIN THREE MINUTES, THE AFFECTED ENGINE SHOULD BE SHUT DOWN. THE LANDING GEAR MAY HAVE TO BE RETRACTED TO SUSTAIN FLIGHT UNTIL ARRIVING AT A SUITABLE LANDING FIELD.
EMERGENCY PROCEDURE FLASHING LIGHT: Indicates a wing leading edge bleed air line failure or an overheated generator wire. *1. BLEED AIR SWITCH (affected side)……......................................... OFF 2. GENERATOR SWITCH (affected side)…......................................... OFF CAUTION IF THE WARNING LIGHT DOES NOT EXTINGUISH WITHIN THREE MINUTES, THE AFFECTED ENGINE SHOULD BE SHUT DOWN.
