NOTES:
• Refer to Appendix E for message details and suggested resolution for each message.
• A vertical profile and associated trip predictions are only generated for the Active and Modified route. Trip
predictions are available for the inactive route.
• There may be differences between the distances displayed on the LEGS pages and the VNAV pages. This
is because the distances displayed on the LEGS pages do not take into account the waypoint transition
paths (fly-by or fly-over).
• T/O DATA DELETED: When raised, all entered takeoff speeds are automatically deleted.

Computation of a vertical profile is required for the FMS to provide performance predictions (E
