The FMS has the capability to constrain the aircraft to an altitude at a waypoint in
cruise. The format is /SFLXXX which is entered on the right side of the ACT
F-PLN page adjacent to the desired constraining waypoint with a flight level of
XXX. The flight level must be equal to one of the flight levels on the F-PLN INIT
page. This capability applies primarily in step climb between flight levels defined
in the FMS. Once the aircraft sequences the waypoint which has the constraining
altitude and sequences the step climb point for that altitude, a vertical alert will be
provided and the aircraft will begin to climb provided the FCP altitude has been
raised to the new cruise flight level.
