INDEX
When a descent leg is captured (i.e., vertical deviation becomes valid), Vertical Path Tracking becomes
active and tracks the descent profile. An altitude capture mode (‘ALTS’ or ‘ALTV’) is armed as appropriate.

If the Altimeter’s barometric setting is adjusted while Vertical Path Tracking is active, the flight director
increases/decreases the descent rate by up to 500 fpm to re-establish the aircraft on the descent path (without
commanding a climb). Adjusting the altimeter barometric setting creates discontinuities in VNV vertical
deviation, moving the descent path. For large adjustments, it may take several minutes for the aircraft to re-
establish on the descent path. If the change is made while nearing a waypoint with a VNV Target Altitude,
the aircraft may not re-establish on the descent path in time to meet the vertical constraint.
