Use constraints with ALTSEL

Review ALTSEL

Plan a climb with a published intermediate altitude restriction and a higher final cleared altitude. ^[201]

Review the active constraint and ALTSEL before the aircraft reaches the restriction.

VNAV limits

Altitude / FMA

Watch the FMA and altitude capture while comparing the FMS constraint with the preselected altitude.

FSS describes FMS targets and ALTSEL as interacting limits in VNAV.

FPL and selected altitude

Check the active flight plan, clearance and selected altitude; do not remove a restriction without an appropriate clearance.
