1.12.2.2. Roll FLCS
The roll rate is limited to half the value of the Cruise gains. It is totally independent of AOA, airspeed
and horizontal tail position.
1.12.3. STANDBY gains
The FLCS Standby gains is a backup mode that automatically kicks in whenever a FLCS fault is
detected (i.e. whenever the FLCS warning light and FLCS FAULT caution light are illuminated).
Control response is then tailored for a fixed speed and altitude (around 600 knots for gear up and 230
knots for gear down). If the FLCS Fault can be reset with the FLCS RESET switch the FLCC will revert
to its previous gains, clearing the Standby gains. This is indicated by the warning light going off.

1.12.4. Gun compensation
The FLCS automatically compensates for the off-centre gun firing and the gun gas emissions during
gun firing by moving the rudder and flaperons. Gun compensation is optimised for 0.7
– 0.9 Mach.
Firing outside of those speeds may create adverse effects. Furthermore if the FLCS is damaged, firing
the gun may be impossible because of the lack of compensation.
1.12.5. Leading Edge Flaps (LEF) and Trailing Edge Flaps (TEF)
BMS also models the impact of LEF and TEF motion behaviour. Normally these flight controls are
commanded by the FLCS but they can be locked in place with the FLCP (FLCS Panel) switches or by
malfunctions or damage.
LEF are controlled by the FLCS as a function of MACH and AOA.
TEF are controlled by the FLCS as a function of Landing Gear handle position, ALT FLAPS switch
position and airspeed.
