Flight Control

With this panel you can use the functions of the flight controls system (FLCS) or flight control computer (FLCC). The Side Stick Controller is also part of this system. If the FLCS is damaged, you can manually access the flaps by using this panel. The panel is located on the left console.

EXTENDTrailing edge flaps (TEF) extend regardless of LG handle.
NORMTrailing edge flaps (TEF) operation controlled by LG handle.
MANUAL TF FLYUP2-Way switch
(lever lock)
DISABLEFly-up protection not available in manual trailing flaps (TF).
ENABLEFly-up protection available in manual trailing flaps (TF) for TF or SWIM detected failure.
Status light2-Status lightRUN
(green)
FLCS BIT is running.
FAIL
(red)
Failure during the FLCS BIT.
LE FLAPS2-Way switch
(lever lock)
LOCKManually locks leading edge flaps (LEF) in present position and illuminates the FLCS warning light and FLCS LEF LOCK PFL.
AUTOLeading edge flaps (LEF) are automatically controlled as a function of mach number, altitude and AOA.
FLCS2-Way switch
(spring-loaded)
(safety frame)
RESETMomentary position which performs servo or electronic reset of FLCS system failures. Resets FLCS warning light, CADC, FLCS FAULT and MASTER CAUTION lights and clears PFL's if fault is cleared.
OFFNormal position
BIT2-Way switchBITCommands build in test (BIT) if weight is on main LG and wheel speed is less than 28 knots ground speed.
OFFNormal position

HORIZ tail
servo arm
3-Way switchL ARMArms servo monitor. Subsequent failure in left ISA will position left horizontal tail to neutral, will lock out roll commands to the right horizontal tail, and will illuminate the DUAL FC warning light.
CenterNormal position.
R ARMArms servo monitor. Subsequent failure in right ISA will position right horizontal tail to neutral, will lock out roll commands to the left horizontal tail, and will illuminate the DUAL FC warning light.
L FLAPERON servoStatus lightL (amber)On, than indicates first failure of left flaperon ISA
R FLAPERON servoStatus lightR (amber)On, than indicates first failure of right flaperon ISA
FLAPERON
servo arm
3-Way switchL ARMArms servo monitor. Subsequent failure in left ISA will position left flaperon to neutral, will lock out trailing edge flaps (TEF) commands to both flaperons, and will illuminate the DUAL FC warning light.
CenterNormal position.
R ARMArms servo monitor. Subsequent failure in right ISA will position right flaperon to neutral, will lock out trailing edge flaps (TEF) commands to both flaperons, and will illuminate the DUAL FC warning light.
RUDDER servoStatus light. (amber)On, than indicates first failure of rudder ISA.
RUDDER
servo arm
2-Way switchARMArms servo monitor. Subsequent failure of ISA will position rudder tio neutral and will illuminate the DUAL FC warning light.
Not armed (center)Normal position
SELF TEST2-Way switchTESTIndicates FLCS self-test.
OFFDeenergizes self-test circuits.
ADV SLEW3-Way switch
(spring-loaded)
ADVAdvances the test program after a stop in test procedure.
CenterNormal position
SLEWAdvances the test sequence approximately one test number per second.
Test ADVStatus lightADV (green)Indicates a stop in test program wich requires manual advance.
Test MALStatus lightMAL (amber)If accompanied by a dot light, indicates a malfunction in the FLCS has been detected during self-test.
Test number7 Segment display2 Digits
(green)
Indicates step number of test being performed. This display has four dot lights around the numbers. The dot light in the left upper corner is spare. The "Rate Gyro Speed Detect Dot Light" in the right upper corner indicates rate gyro failure. The "ECA (=Electronic Component Assembly) Data Word Dot Light" in the lower left corner indicatesis failure in ECA. The "FLCC (=Flight Control Computer) Data Word Dot Light" in the lower right corner indicates failure in FLCC.
MONConnector?Test monitor receptacle. Connection for external test equipment.
FCS CAUTION RESETButtonPushResets FLT CONT SYS caution light so that subsequent failures can be indicated and gives consent to allow SERVO reset. Also resets MASTER CAUTION light caused by FLT CONT SYS caution light illumination. Depressing FCS CAUTION RESET button in flight also causes the FLCS data recorder to store a frame of data.
SERVO ELEC RESET3-Way switch
(spring-loaded)
(safety frame)
SERVOResets all failed ISA's when the FCS CAUTION RESET button is depressed simultaneously and illuminates five SERVO lights to test bulbs.
CenterNormal position
ELECResets malfunctioning pitch, roll, yaw, ADC, LE FLAPS and CADC electronics. All resets FLT CONT SYS and MASTER CAUTION lights.
ALT FLAPS
(lever lock)
2-Way switchNORMTrailing edge flaps (TEF) operation controlled by LG handle.
EXTENDTrailing edge flaps (TEF) extend regardless of LG handle.
PitchStatus lightP (amber)Indicated signal malfunction in pitch control electronics.
RollStatus lightR (amber)Indicated signal malfunction in roll control electronics.
YawStatus lightY (amber)Indicated signal malfunction in yaw control electronics.
LE FLAPS2-Way switchAUTOLeading edge flaps (LEF) are automatically controlled as a function of mach number, altitude and AOA.
LOCKLocks leading edge flaps (LEF) in present position and illuminates LE FLAPS caution light.
STBY GAINLight. (amber)On, than indicates FLCS is operating on standby gains.
