An avionics fault was detected. Refer to PFLD message and press F-ACK button to reset
the AVIONICS FAULT caution light. Perform fault recall with a further press of F-ACK to
determine if the failure condition still exists. See 3.4. PFL Analysis.
Cooling of the avionics equipment is insufficient. AIR SOURCE knob position should be
checked immediately. If AIR SOURCE was not in NORM place it in NORM and the fault
will clear as soon as cooling becomes effective again. If AIR SOURCE was in NORM expect degraded
avionic equipment performance and FCR shutdown. Retard throttle to 80% and shut down non-
essential avionics. Land as soon as practical.
Malfunction of the radar altimeter. Move the radar altimeter switch to OFF. A-LOW will not
be available anymore.
The IFF caution light illuminates whenever there is a condition to prevent Mode 4
operation: IFF in standby; Mode 4 disabled; Mode 4 keys zeroed, RF switch in SILENT.
The IFF caution light will also illuminate briefly whenever your IFF is unable to answer a Mode 4
query. Depending on your IFF settings an audio cue may also sound at the same time. This caution
light does not trigger a MASTER CAUTION light.
Malfunction in the NUCLEAR control circuitry which is irrelevant in BMS. This caution light
is advisory and has no consequence in BMS.
This caution light illuminates whenever the ejection seat lever is up (system safe).
If desired simply arm the seat and the caution light will clear.
The Nose Wheel System (NWS) has failed and steering with the nose gear is not
possible. Steering can be done with the rudder, but will become less effective at low
speed. Differential toe brakes can be used at low speeds but beware of hot brake risks.
The anti-skid system is not implemented in BMS. This caution light has no consequence.
It does come on with the MAL & IND LTS test though.
The hook is not up and locked. Cable arrestment system is not implemented in BMS and
the hook has no real purpose. Change the position of the HOOK switch on the gear panel
to clear the fault.
The OBOGS caution light illuminates when the ECS air supply has dropped below 10 psi.
Oxygen production has stopped (not that it really matters to us). Expect an OXY LOW
warning light.
The CABIN PRESS caution light comes on when the cockpit pressurisation is above
27000 feet. Check AIR SOURCE knob for NORM position. If caution light remains
illuminated descend below 25000 feet and reduce speed to 500 knots maximum. Flight can be
continued below 25000 feet as oxygen is available. Hypoxia is now modelled in 4.34 and you will
blackout if you don’t descend quickly enough. If you do blackout and you are descending you will
recover when you get low enough, unless you hit the ground first!
