CALCULATED AIR RELEASE POINT (CARP) AND HIGH ALTITUDE RELEASE POINT (HARP) (If
configured)
NOTE: Hereafter, unless specifically mentioned references to ‘Calculated Air Release Point’ or ‘CARP’ also
includes and pertains to the following procedures: Custom HARP, Custom HAHO, Free Fall.
The Calculated Air Release Point function is a tactical function used for air drops of personnel, cargo, or heavy
equipment. In the FMS, the CARP procedure is defined as a series of six legs/waypoints, as shown in the following
figure, five of which are calculated by the FMS:
1. Identification Point (IP) - Optional user-defined waypoint that may be used as a reference for a Mark on Top
operation.
2. Turn Point (TP) - FMS computed waypoint used to align the aircraft along the track of the drop zone. The TP-
SD leg is a turn such that the track becomes the same direction as the landing zone and the wings are level
upon reaching the slow-down point.
3. Slowdown Point (SD) - FMS computed waypoint used to signal to the pilot that the altitude and speed must be
changed to the CARP target altitude and speed. The SD-CRP leg is along the same track as the drop zone
and its length is computed to allow the aircraft sufficient time to reach the target altitude and speed prior to
reaching CARP.
4. CARP Point (CRP) - FMS computed waypoint indicating that the drop may begin; green light indication. This
waypoint is computed using the provided Point of Impact and Ballistics parameters.
5. Extended Trailing Edge (XTE) Point - FMS computed waypoint indicating the drops must cease; red light
indication. The direction and length of the CRP-XTE leg are the same as the drop zone.
6. Escape Point (ESC) - FMS computed waypoint indicating the aircraft may now change track and proceed with
the following waypoint. This waypoint is computed from the escape time and speed during the drop.
