7. AUTOPILOT DISCONNECT WARNING INDICATOR LIGHT (DISC WARN) -
Whenever the autopilot is disengaged by any means, other than the control wheel
AUTOPILOT DISENGAGE switch, the autopilot disconnect warning indicator
light (DISC WARN) will illuminate yellow and will remain lighted until it is
cancelled by pressing the control wheel AUTOPILOT DISENGAGE switch. When
the DISC WARN indicator light is activated, the circuit will also automatically
activate an autopilot disengage warning horn that will produce a short tone
lasting from 1 to 2 seconds with decreasing amplitude.
8. AUTOPILOT DISCONNECT TEST BUTTON (TEST EA FLT) - When the TEST
EA FLT pushbutton is pressed and held with the autopilot engaged, the "G" switch
in the acceleration sensor is actuated and if the "G" switch is functional, the
AP I ON-OFF switch will automatically disengage, the autopilot disconnect horn
will produce a short tone and the yellow autopilot disconnect warning (DISC
WARN) light will illuminate to advise the pilot the "G" switch disengaging
function is operational.
9. FLIGHT DIRECTOR (FD) MODE SELECTOR SWITCH - Engages flight director
mode. FD annunciator will illuminate green and command bars (22) on the
attitude gyro (FDI) will appear.
10. AUTOPILOT (AP) MODE SELECTOR ANNUNCIATOR LIGHT - AP annuncia-
tor will illuminate green when autopilot is engaged.
11. NAV 1/NAV 2 MODE SELECTOR SWITCH - Permits selection of either one of
the two Nav receivers to be coupled to the Integrated Flight Control System by
pressing the NAV 1/NAV 2 pushbutton. The NAV 1/NAV 2 annunciator will
illuminate green to show NAV 1 when engaged. By pressing NAV 1/NAV 2 a
second time the alternate NAV 2 receiver will be coupled, NAV 1 will be dropped
out and the annunciator light NA V 2 will illuminate green.
12. BACK-COURSE (BC) MODE SELECTOR SWITCH - Used with localizer opera-
tion only. With AP switch (on control unit) or FD pushbutton ON an~. when
associated navigation receiver selected by NAV 1/NAV 2 is set to a localizer
frequency, it will always reverse localizer signals to the computer for back-
course operation which provides the capability to fly the localizer back-course
inbound or the front course outbound. BC annunciator on mode selector will
illuminate green when engaged. It also reverses normal localizer needle indica-
tion on the #2 navigation CDI needle.
13. GO-AROUND (GA) AND GLIDE SLOPE (GS) MODE SELECTOR ANNUNCIA-
TOR LIGHTS - GA annunciator illuminates green when go-around switch on
control wheel is pressed; indicates that all modes of operation, including autopi-
lot, except a preset pitch-up and wings-level flight director command, are
cancelled. The GA mode may be cancelled by repressing the GA switch, pressing
the HDG pushbutton or reengaging the autopilot. During approach, GS annuncia-
tor illuminates green when glide slope is captured by IFCS.
14. VOR/LOCALIZER (VOR/LOC) MODE ANNUNCIATOR LIGHTS - When NAV
pushbutton is engaged, either the VOR or LOC annunciator will illuminate green
to reflect the selected frequency on the selected nav receiver. VOR/LOC light will
only illuminate while in NA V mode.
