CAUTION LIGHTS Flashcards
< 11 – 15 PSI downstream of the centrifugal pump.
* Single light = centrifugal pump fail, both lights = electric boost pump fail (below 20,000’ single pump is sufficient)
< 11 – 15 PSI downstream of the centrifugal pump.
* Single light = centrifugal pump fail, both lights = boost pump fail (below 20,000’ single pump is sufficient)
< 11 – 15 PSI downstream of the centrifugal pump.
* Single light = centrifugal pump fail, both lights = boost pump fail (below 20,000’ single pump is sufficient)
< 50 psi O2 (normal 70-100 psi)
or total remaining O2 < 3 Liters (of 30 Liters max)
Canopy open or unlocked
Windshield switch is placed in the AIR position
Generator failure
or CSD overspeed or malfunction
If both GEN INOP no light unless rat is operating.
Generator failure
or CSD overspeed or malfunction
If both GEN INOP no light unless rat is operating.
Dual GEN failure *Memory items*
If both GEN INOP no caution lights unless rat is operating.
Fuel < 2500 lbs (AOA ~ 6.5 units)
Fuel < 1800 lbs (Higher AOAs)
AC Essential Bus Failure
(Thermistors immersed in fuel)
SHIP: Nose towlink lowered, Throttles > 83±3%, AND Cat grip stowed
RUNWAY: nosewheel cocked and the power above 83 ±3% (center nosewheel to turn off)
AIRBORNE: Main gear extended, flaps not fully up, power below 83±3%, & the nose strut hard.
- DSDC detects an internal fault
- On power-up until a stable platform is attained
< 5 PSI in the electronic cooling duct
Air Temp flowing to electronic equip too high:
- High temperature air closes the temperature switch.
- The aft equipment temperature valve closes and remains closed. Full cold air flows to electronic equipment.
- Simultaneously, the ELEC HIGH AIR TEMP light on the caution lights panel and the light on the reset panel (in the aft compartment) comes ON.
- As the temperature of the air drops, the light onthe caution lights panel goes out.
Extended rudder travel actuated in clean configuration
AYK-14 (CMC) is excessive.
If power is secured to the AYK—14 (CMC), the CMPTR TEMP light will go out, but a cooling air problem may still exist.
ON - Flight or combined system < 1,400 ±100 psi
OFF – Both > 1,900 psi
* Successive system failures will not cause Master Caution to light
Unsolicited < 20%
Solicited 20 – 80%
Unsolicited < 20%
Solicited 20 – 80%
(1) ANTI-SKID switch is off, (2) extended or rotated parking brake handle, (3) a brake release signal > 3.5 seconds, (4) anti-skid control box failure.
* Light disabled until landing gear is lowered & port forward main gear door closed.
FLAP selector lever and the EMERG FLAP switch are in positions such that opposing commands are being issued (other than OFF)
> 5 psi ΔP between filter inlet and outlet
(Bypass Valve opens 8-10 psi)
> 5 psi ΔP between filter inlet and outlet
(Bypass Valve opens 8-10 psi)
AIR CONDMASTER switch placed to OFF
Improper Mode 4 response.
* does not illuminate MASTER CAUTION light
Fuselage fuel cell > 7 PSI (Norm 1.25-2 PSI)
Fuselage fuel system is overpressurized as a result of:
Fuel system malfunctions, high speed flight, simultaneous emptying of wing/centerline drop tanks, fuel system malfunctions while refueling, or a combination
CSD Oil Temp >260° +/- 10° F
(CSD uncouples at 354° F)
