i was out of WW for a nav exercise, (rhs) and got lost over approx compton abbas.
it would have been really nice to have a gps map display just to check where we where.
i thought i was a half decent map reader, (ex rally navigator), but it was disconcerting for me as a student to realise that from the air, towns and roads etc.. look very much alike.
situational awareness is essential, imho.
