3.7. IN FLIGHT EMERGENCIES
3.7.1 COCKPIT PRESSURE MALFUNCTIONS
Illumination of the CANOPY warning light indicates a loss of cockpit pressure. It may be caused by the
canopy seal or a failure or shutdown of the ECS system. If cockpit pressure exceeds 27000 feet the
CABIN PRESS caution light will illuminate; descend below 25000 feet altitude and maintain a speed
under 500 knots. The flight can be continued below 25000 feet.
H
ypoxia 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!
3.7.2 EQUIP HOT CAUTION LIGHT
As always in this case the first item to check is that the position of the AIR SOURCE knob is in NORM.
Reduce power to 80% RPM. Another reason why EQUIP HOT might be illuminated is flying for long
periods with the gear extended at low level. Indeed flying below 8000 feet for more than 7 to 8 minutes
with the gear down might shut the ECS off. If EQUIP HOT remains on shut down all non-essential
avionics (the FCR will be shut down automatically) and land as soon as practical.
3.7.3 EJECTION
Since there is absolutely zero risk of death or even injury in our hobby, there should be no qualms
about ejection when necessary; just pull the handle and off you go to meet the silk.
3.7.4 ELECTRICAL SYSTEM FAILURE
Electrical System failures are indicated by illumination of the ELEC SYS caution light. Refer to Chapter
1.9 Electrical System for troubleshooting. The ELEC SYS caution light cannot be reset with the
MASTER CAUTION light. The CAUTION RESET pushbutton on the ELEC panel is used to reset any
ELEC SYS caution light.
3.7.5 ENGINE MALFUNCTIONS
4.34 introduced more possibilities to have engine trouble in flight. Nearby explosions (AAA or SAM)
may cause your engine to flameout, fuel starvation may occur when running on fumes due to
unreliable fuel gauges, particularly with negative G. In most cases engine restart may be attempted
with an air-start procedure.
3.7.5.1 Air-Start
Air start procedures differ depending on the setting of the Idle Cutoff option in
Falcon BMS.cfg
.
With that Config option deactivated (default) you will need the (unrealistic) idle detent keystroke.
If you have the Idle Cutoff option in
Falcon BMS.cfg
enabled then you rely on your flight controller
’s
mechanical detent for the idle detent, making the keystroke unnecessary.
The first indications of an engine shutdown are a decrease in RPM and FTIT (and engine noise).
If the EPU is in NORM it will immediately start running to power the emergency and hydraulic buses.
Depending on RPM % the EPU may also start to deplete the hydrazine. Remember an EPU running
on hydrazine will only last about 10 minutes before it runs out of fuel.
When the engine flames out in flight engine RPM may still remain high enough, especially in a dive
due to air flow spinning the turbine, to restart the engine if RPM is above 20-25%.Air-start can thus be
initiated without use of the JFS.
JFS assisted air-starts are only necessary when engine RPM has decayed below the 20-25% limit.
Air-start efficiency in BMS is not currently dependent on altitude.
