• Cruise: The cruise phase starts with the capture of the cruise altitude and ends at the beginning of the
descent phase. The cruise profile takes into account the crew-selected speed schedule and constant
speed segments, all cruise waypoint altitude and speed constraints, blended winds and temperature.
• Step Climbs/Descents: As many pre-planned step climb/descent altitudes as desired can be inserted as
waypoint altitude constraints, except for waypoints within 50 nm of the T/D. A climb or descent in cruise is
flown at the current cruise speed.

Supported waypoint altitude constraint types are:
• AT (e.g. FL270), AT or ABOVE (e.g. FL290A), AT or BELOW (e.g. FL150B
