I remember programming the waypoints flow in reverse order (or whatever order you want).
From the manual:
Changing WP Sequence in Flight When you wish to change the WP sequence, you can perform the following procedure:
Disengage ROUTE mode by setting the “МАРШРУТ-СНИЖЕНИЕ” (ROUTE - DESCENT) switch on the collective to the neutral position.
Turn off the “ППМ” (Waypoints) push-light on the PVI-800 Navigation Control panel. This light and the WP indication number on the display will go out.
Press the “ППМ” (Waypoints) push-light and it will illuminate.
On the Navigation Control panel keypad, set the new first WP by pressing the corresponding keypad button. The number (WP), will then be visible on the display.
Press the “ВВОД” (ENTER) push-light and the first WP will be saved into navigation computer memory.
Repeat this process for the next five WPs.
When complete, turn off the “ППМ” (Waypoints) mode. The new WP sequence will be saved in navigation computer memory.
To activate the new route, press the “ППМ” (Waypoints) push-light again (the number of the first WP and navigation data will appear in the display) and check the correct flight direction to the new, first WP of the route.
Engage ROUTE mode by setting the “МАРШРУТ-СНИЖЕНИ" (ROUTE – DESCENT) switch on the collective to the ROUTE position. According to the selected DH or DT sub-mode, the “МАРШРУТ ЗК” or “МАРШРУТ ЛЗП” (DH ROUTE or DT ROUTE) lights will illuminate and the helicopter will initiate automatic turns to complete the new route.
BTW, RTFM ;)
