To carry out a co-ordinated search plan, the best way of defining and subdividing the search area should be considered. Once designated, search teams should confirm this, and provide regular updates to the incident commander.
Establish clearly defined parameters of the search area and subdivide into appropriate sizes depending on:
- Natural features
- Type and size of transport involved
- Available resources
If visibility is reduced, or at night, give additional consideration to using safe routes and landmarks.
