• The step climb is a performance climb while the step descent is an idle-thrust descent. Both are flown at the
cruise speed.
• It is recommended not to make FGCP altitude changes (SEL ALT) while the FMS FPLAN is in the MOD-
ified state.
• A CHECK SELECTED ALT message will be raised at 10 nm prior to the step point if the FGCP selected
altitude is not within 150 ft of the planned step altitude.
• Pre-planned Step Climbs/Descents cannot be inserted into the active flight plan if the step point is within 50
nm of the predicted Top-of-Descent.
