Create a User Waypoint By Basic Grid
This feature allows you to set a waypoint on the
southeast corner Basic Grid coordinate as a User
waypoint. You can then fly Direct-To the starting
point in a grid for flying a search pattern. You must
have selected the Basic Grid type on the SAR Setup
page (see page 16) to have this display available.
The SAR Position (see page 18) is a reference point
on the southeast corner of a 10° by 10° grid. Each one
degree grid is then divided into 30’ and 15’ segments
which are noted by alpha characters.
