This is more a navigation demo than actual search.
The mission consists of consecutive passes over the search area while advancing 50m after every turn.
The area covered is around 200x200m, flight time around 10min, altitude 100m AGL.
Return-home position was right over the takeoff, at 50m AGL, tested briefly just after the takeoff. Some 60s after the takeoff RC transmitter power was completely turned off in order to spare the battery, F/S settings using Futaba PCM kept the autopilot enabled, flying the pattern without emergency return-home.
After the climb the motor is typically inaudible at 200m.
the takeoff was manual, engaged autopilot 10s after.
the landing was manual as well.
There is sparse fog, 1h before dusk.
Used Nikon Coolpix S1, 15FPS only, only 320x240 real resolution due to ultra strong QuickTime compression.
The airplane is a production prototype (RCM Pelikan Focus) using Flexipilot Lite with 4DOF IMU.
