I have a £99 Garmin E-trex,it gives me bearing,distance and time to a waypoint,speed over ground and track,probably more stuff if I wanted to find out.
I have several local waypoints programmed in and for my purposes it is all I need as a back up.
The other point,flying locally I could find at least 5 other airfields not counting Norwich within 20 miles without a chart or GPS.
Plus several private strips.
If you were really lost I think you could always ask for a QDM into an ATC airfield.
Last point,I was going flying today but it really is too bl**dy cold here,the L4 has so many draughts that one soon becomes quite perished,it happens quite quickly from being comfortable for say 40 mins and then rapidly having "near hypothermia" when you start to feel cold from the inside and it takes quite a while to warm up when landed.
Never mind,days getting longer and it'll soon be Springtime!
