INTERACTIONS WITH VERTICAL 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.
LOCALIZER MODE THROUGH THE L0C PUSHBUTTON
This mode captures and tracks a Iocalizer beam independently of the glide path beam.
Pilots use it to fly Iocalizer-only approaches or to initiate an ILS approach when intercepting
the glide slope from above.
ARMING CONDITIONS
The pilot arms the LOC mode by pressing the LOC pushbutton, provided that
- An ILS is tuned (frequency and runway course).
- The aircraft is above 400 feet RA.
- TO or GA mode is not engaged.
DISARMING CONDITIONS
LOC mode is disarmed by :
- Pressing the LOC pushbutton 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 pilot presses the LOC pushbutton again (engaging the HDG/-rRK mode on the
current HDG/-FRK).
