RENDEZ-VOUS WITH A MOVING WAYPOINT (If configured)
The CMA-9000 FMS is capable of providing aircraft guidance to a “rendez-vous” point with a moving waypoint
(defined as described in the Sub-Section, Manual Entry Of A Moving User Waypoint In The Database). The
“rendez-vous” is an intercept point with the moving waypoint trajectory.
A rendez-vous position is determined once a moving waypoint is inserted in the flight plan and every 10 seconds
from there on. The rendez-vous position is recomputed as long as the Time To Go (TTG) is over one minute.
In the case of an achievable rendez-vous, the CMA-9000 FMS uses the rendez-vous position in the flight plan
and provides guidance data relative to the direct course computed inbound to this rendez-vous position.
In the case of an unachievable rendez-vous, the CMA-9000 FMS uses the moving waypoint position in the flight
plan and provides guidance data relative to the bearing to the moving waypoint.
The CMA-9000 FMS defines the moving waypoint inserted in the route as a fly-over.
The CMA-9000 FMS considers a rendez-vous unachievable in any of the following conditions:
1. The moving waypoint is the active waypoint and interception of the moving waypoint is not possible within a
traveling distance of 500 nautical miles from the current position.
2. The moving waypoint is in the active route but is not the active waypoint and interception of the moving
waypoint is not possible within a traveling distance of 500 nautical miles from the previous waypoint.
3. The moving waypoint is in the modified route but is not the first waypoint and interception of the moving
waypoint is not possible within a traveling distance of 500 nautical miles from the previous waypoint.
4. The moving waypoint is the first waypoint of the modified route and interception of the moving waypoint is
not possible within a traveling distance of 500 nautical miles from the current position.
In condition 1, the CMA-9000 FMS generates a !RENDEZVOUS UNACHIEVABLE alert message and
invalidates its roll command output.
In conditions 2 to 4, the CMA-9000 FMS generates a !RENDEZVOUS UNACHIEVABLE advisory message.
When a rendez-vous is determined while on ground, the CMA-9000 FMS uses the CRZ_TAS and CRZ_WIND
values on the PLAN DATA page for the rendez-vous computation.
