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.

The panel and his elements (Block 40/42 current, 50/52)

Element	Type	Position	Information
DIGITAL<	2-Way switch (lever lock)	BACKUP	Selects backup software program within the FLCC.
DIGITAL<	2-Way switch (lever lock)	OFF	Normal position.
ALT FLAPS	2-Way switch (lever lock)	EXTEND	Trailing edge flaps (TEF) extend regardless of LG handle.
ALT FLAPS	2-Way switch (lever lock)	NORM	Trailing edge flaps (TEF) operation controlled by LG handle.
MANUAL TF FLYUP	2-Way switch (lever lock)	DISABLE	Fly-up protection not available in manual trailing flaps (TF).
MANUAL TF FLYUP	2-Way switch (lever lock)	ENABLE	Fly-up protection available in manual trailing flaps (TF) for TF or SWIM detected failure.
Status light	2-Status light	RUN (green)	FLCS BIT is running.
Status light	2-Status light	FAIL (red)	Failure during the FLCS BIT.
LE FLAPS	2-Way switch (lever lock)	LOCK	Manually locks leading edge flaps (LEF) in present position and illuminates the FLCS warning light and FLCS LEF LOCK PFL.
LE FLAPS	2-Way switch (lever lock)	AUTO	Leading edge flaps (LEF) are automatically controlled as a function of mach number, altitude and AOA.
FLCS	2-Way switch (spring-loaded) (safety frame)	RESET	Momentary 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.
FLCS	2-Way switch (spring-loaded) (safety frame)	OFF	Normal position
BIT	2-Way switch	BIT	Commands build in test (BIT) if weight is on main LG and wheel speed is less than 28 knots ground speed.
BIT	2-Way switch	OFF	Normal position

The panel and his elements (Block 25, 30/32, 40/42 old, MLU)

Element	Type	Position	Information
L HORIZ tail servo	Status light	L (amber)	On, than indicates first failure of left horizontal ISA
R HORIZ tail servo	Status light	R (amber)	On, than indicates first failure of right horizontal ISA
HORIZ tail servo arm	3-Way switch	L ARM	Arms 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.
		Center	Normal position.
		R ARM	Arms 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 servo	Status light	L (amber)	On, than indicates first failure of left flaperon ISA
R FLAPERON servo	Status light	R (amber)	On, than indicates first failure of right flaperon ISA
FLAPERON servo arm	3-Way switch	L ARM	Arms 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.
		Center	Normal position.
		R ARM	Arms 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 servo	Status light	. (amber)	On, than indicates first failure of rudder ISA.
RUDDER servo arm	2-Way switch	ARM	Arms servo monitor. Subsequent failure of ISA will position rudder tio neutral and will illuminate the DUAL FC warning light.
RUDDER servo arm	2-Way switch	Not armed (center)	Normal position
SELF TEST	2-Way switch	TEST	Indicates FLCS self-test.
SELF TEST	2-Way switch	OFF	Deenergizes self-test circuits.
ADV SLEW	3-Way switch (spring-loaded)	ADV	Advances the test program after a stop in test procedure.
		Center	Normal position
		SLEW	Advances the test sequence approximately one test number per second.
Test ADV	Status light	ADV (green)	Indicates a stop in test program wich requires manual advance.
Test MAL	Status light	MAL (amber)	If accompanied by a dot light, indicates a malfunction in the FLCS has been detected during self-test.
Test number	7 Segment display	2 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.
MON	Connector	?	Test monitor receptacle. Connection for external test equipment.
FCS CAUTION RESET	Button	Push	Resets 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 RESET	3-Way switch (spring-loaded) (safety frame)	SERVO	Resets all failed ISA's when the FCS CAUTION RESET button is depressed simultaneously and illuminates five SERVO lights to test bulbs.
		Center	Normal position
		ELEC	Resets 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 switch	NORM	Trailing edge flaps (TEF) operation controlled by LG handle.
ALT FLAPS (lever lock)	2-Way switch	EXTEND	Trailing edge flaps (TEF) extend regardless of LG handle.
Pitch	Status light	P (amber)	Indicated signal malfunction in pitch control electronics.
Roll	Status light	R (amber)	Indicated signal malfunction in roll control electronics.
Yaw	Status light	Y (amber)	Indicated signal malfunction in yaw control electronics.
LE FLAPS	2-Way switch	AUTO	Leading edge flaps (LEF) are automatically controlled as a function of mach number, altitude and AOA.
LE FLAPS	2-Way switch	LOCK	Locks leading edge flaps (LEF) in present position and illuminates LE FLAPS caution light.
STBY GAIN	Light	. (amber)	On, than indicates FLCS is operating on standby gains.
