1.2.1.13 ENG & JET START panel
The main purpose of this panel is to start the engine. This is done using the JFS
(Jet Fuel Starter) switch. The JFS is an independent gas turbine and is started by 2
JFS/brake accumulators which are charged automatically by hydraulic system B.
The JFS is used to start the engine on the ground and to assist in engine airstarts.
The switch is a magnetically held 3-position switch, magnetically held in START1
or START2. Currently in BMS we only use the START 2 position with a RIGHT
mouse click (down is always right click).
When placed in START 2 the JFS spools up and drives the main engine turbine
shaft RPM to 20-25%. If you have a suitable throttle (with a strong idle detent) and
have the Idle Cutoff option box checked in
Falcon BMS.cfg
the throttle can then be
moved out of its CUTOFF position to IDLE, which starts the main engine as it does
in the real jet. In BMS this can also be done with the throttle detent key callback.
The JFS/brake accumulator starts to recharge past 12% engine RPM with HYD B pressure and takes
between 40 and 60 seconds to regain a full operating pressure charge. The JFS automatically shuts
down when the engine RPM passes 55%. The switch then snaps back to OFF.
Since BMS 4.33 the green JFS run light no longer comes on as soon as the JFS is activated but
illuminates around 15 seconds later once the JFS has attained nominal operating speed.
In 4.34 the JFS light state will indicate JFS status: a JFS light flashing once every second will indicate
a JFS overheat and a JFS light flashing twice per second will indicate a JFS failure.
The ENG CONT PRI/SEC is a two-position switch guarded in PRI, which is the normal (primary)
engine operating mode. The engine transfers automatically to SEC mode in the case of any failure of
the Digital Electronic Control (DEC). It can manually be transferred to SEC by placing the ENG CONT
switch in SEC. Transfer is indicated by the SEC caution light on the warning panel. When operating in
SEC the engine exhaust nozzle remains closed and afterburner is inhibited (nozzle is now visible in
multiplayer).
The AB RESET and MAX POWER switches are not implemented in BMS.
