Oh what!!
Been a PPL -IMC holder now for 13 years and it scares me what been written on this thread! Even in local area sightseeing I work out a route/timings/fuel, ok have a black and white GPS on standby. Im an ATC and the amount of peeps i here going im 15.25miles from your Overhead......grrrr try it without a GPS. A few cant tell the difference between airspace as wel!! A to B lines great!! Ok i understand technology is great but when it goes wrong? U have to have a plan! I remember flying in Norfolk and me mates GPS didnt have a signal....flatest place in UK lol
