Back course mode is selected by pushing the B/C switch on the flight control panel. Back course mode is cleared by pushing the B/C switch again, by selecting another lateral mode, or by changing the source of the navigation signal to something other than a localizer.
NOTE
InFDmodewithB/C selected,thelocalizerdeviation is in thecorrectdirection either onthe front or onthe back course. <0026>
Back course mode arming is annunciated with two messages on the primary flight display, a green HDG message in the lateral capture field, and a white navigation source identifier (B/C 1/2) in the lateral arm field. Back course mode capture/tracking is annunciated with a green message in the lateral capture field on the primary flight display which identifies the navigation source (B/C 1/2).
Back course captures are cleared, and/or prevented, in an FCC when the flight director on its side of the aircraft is driven by flight guidance commands from the other FCC.
Back course steering information is invalidated when the navigation source is not alocalizer.
(7) HalfBankMode
Half bank mode reduces the maximum commanded bank angle to 15 degrees. The automatic mode transition will occur at 31,600 feet. Half bank mode has no effect on roll mode operation.

Half bank mode is selected by pushing the 1/2 BANK switch on the FCP. Half bank mode is automatically selected when climbing through 31,600 feet (pressure altitude) or if the aircraft is above the half bank transition altitude when the flight director is turned on. Selection is inhibited when in the take-off mode, go-around mode, on-side approach mode capture, or any on-side localizer capture.
Half bank mode is manually cleared by pushing the 1/2 BANK switch again, and is automatically cleared when descending through the half bank transition altitude.
Half bank is annunciated with a white 1/2 BNK message on the primary flight display.
(8) LateralGo-AroundMode
Lateral go-around mode generates a heading hold command, with a 5 degree bank limit. Selectionoflateral go-around mode turns onbothflight directors, disengages the autopilot, and clears all other lateral modes. Lateral and vertical go-around mode selections are coincident. When lateral go-around causes an autopilot disengage, the resultant autopilot disengage warning may be cancelled by another push of a TOGA switch, or by pushing the AP disconnect switch.
Lateral go-around mode is selected by pushing one of the thrust lever-mounted TOGA switches while airborne. Lateral go-around mode is cleared by selection of FD SYNC or another lateral mode.
Lateral go-around is annunciated with a green GA message in the lateral capture field on the primary flight display.
