Hi,

the attached screenshot shows an appointment realised this morning with a Paparazzi Twinjet aircraft. The plane was asked to fly over waypoint 1, towards waypoint 2, at 7:46:00 UTC. When switched to this navigation block, the aircraft flew over an arc, a straight line and a second arc to arrive on waypoint 1 with the appropriate direction (towards 2). Then it flew a tangent circle which radius were controlled to end at the desired date.

Real UTC time is displayed in the upper left corner (option in the Nav menu). This time is computed from the GPS time of the aircraft. On the figure, the aircraft is about 15m from waypoint 1 . The wind (more than 4m/s, the aircraft flying at 14m/s) is taken into account in the regulation.

Code available in:
 sw/airborne/snav.c
 conf/flight_plan/snav.xml
conf/settings/snav.xml (which allows to set the appointment date from the strip)
