AP/FD LATERAL MODES
When NAV mode is engaged, the vertical managed modes CLB or DES or FINAL take into
account altitude and speed constraints linked to waypoints on the lateral flight plan. If NAV mode
is disengaged, the vertical managed modes are not available and all downpath altitude and speed
constraints are ignored.
Applicable to: ALL
LOCALIZER MODE THROUGH THE LOC PUSHBUTTON
This mode captures and tracks a localizer beam independently of the glide path beam. Flight crew
uses it to fly localizer-only approaches or to initiate an ILS approach when intercepting the glide
slope from above.
ARMING CONDITIONS
The flight crew arms the LOC mode by pressing the LOC pb, provided that:
‐ An ILS is tuned (frequency and runway course)
‐ The aircraft is above 400 ft RA
‐ TO or GA mode is not engaged.
DISARMING CONDITIONS
LOC mode is disarmed by:
‐ Pressing the LOC pb when LOC is armed
‐ Arming the NAV mode
‐ Engaging the GA mode.
Note: Engaging NAV mode by selecting DIR TO does not disarm the LOC mode.
ENGAGEMENT CONDITIONS
The LOC mode engages automatically when capture conditions are met.
DISENGAGEMENT CONDITIONS
The LOC mode disengages:
‐ When another lateral mode is engaged
‐ When the flight crew presses the LOC pb again (engaging the HDG/TRK mode on the current
HDG/TRK).
Applicable to: ALL
LOC BACK COURSE MODE (LOC B/C)
This mode captures and tracks the back beam of a LOC. This approach is considered as a non
precision approach, and must be flown with AP/FD in TRK/FPA modes, A/THR being active.
