Study Notes

Fixing position

Start from the last known checkpoint: heading flown and time elapsed sketch a circle of where I could be.
Match the big, unambiguous features to the sectional — rivers, coastlines, interstates, railroad lines, towers, distinctive towns. Small features lie; big ones don't.
Cross two VOR radials for a fix, or just use the GPS/EFB nearest and own-ship position if available — no points for suffering.
ATC radar can find me too: with a transponder, a controller can identify me from an ident and give vectors.

When it's an emergency

If fuel, daylight, or weather are deteriorating, ask for help early — declaring or squawking 7700 costs nothing and gets full priority. The record shows the pilots who got into trouble are the ones who waited.
