A useful method of a pilot resolving, during a visual flight, any uncertainty in the aircrafts position is to maintain visual contact with the ground and:
set heading towards a line feature such as a coastline, motorway, river or railway.
fly the reverse of the heading being flown prior to becoming uncertain until a pinpoint is obtained.
fly expanding circles until a pinpoint is obtained.
fly reverse headings and associated timings until the point of departure is regained.
