AFM 4-2
Lead In and Overshoot
Lead in and overshoot are utilized to make sure that the aircraft is turning around outside the area of
interest being mapped. The default values of 110 meters lead in and 150 meters overshoot are
suitable for Lynx in most cases.
Statistics
Survey statistics will display information about your survey and polygon. The field of view (FOV) is
the cameras footprint at the survey mission altitude. The photo estimation is the number of photos
you can expect the camera to take during the survey; that number should be below what the
camera’s SD card can store. Lines is the number of flight legs. Distance is linear distance of each
flight leg, excluding turns. Time is the estimated duration to complete the survey. Note that the time
estimate is based on a zero wind situation. High winds increase the time required to complete a
mission because the aircraft’s ground speed is reduced overall. Area is the polygon’s area in square
kilometers.
Rally Points
Rally points are used to control where the aircraft will go given if the following happens:
If the mission is completed, or
If mode rally is commanded, or
If the aircraft loses link with the GCS long enough to trigger the failsafe.
The aircraft will proceed to the nearest rally point within 5 km.
Rally points should be placed at safe locations that will be close enough to you to regain link in the
event of a failsafe.
