Figure 1 – Typical Vertical Profile
The FMS computes the vertical profile made up of take-off and initial climb, climb, cruise, descent, and
approach flight phases. The vertical profile is based on the lateral flight plan, the environmental conditions (e.g.
wind, temperature) and the aircraft/engines’ performance data; it extends as a continuous trajectory between the
departure and destination airports. The missed approach and post-flight phases are also covered in this
section.
