Hope im not as old as i sound but when I learnt to fly GPSs were just being talked about.Everyone couldnt wait.I have been lost ,very lost,I in the end remembered some words from a great mate,He said If you ever get lost land as soon as possible,shut down,get out and have a walk around,then start the flight again.chuck the old wac on the tail and get out the ruler and work something out without having too worry about where you are and wasting fuel as you do soo.This worked for me.Its amazing how much clearer you think when u get some pressure off your self.I was made too fly without captain Garmin when getting checked out on mail runs,didnt have a problem with that,But now im checking guys out and I say go for it use the Gps but also have your head outside and seeying what is actually on track soo if you one day have flat baterys you know that dam with a airstrip is dead on track!!
