In praise of the Garmin 430
A couple of other nice touches to add to FFF's message,
You can treat any waypoint as a VOR, so its very easy to
setup a user waypoint, say three miles east of EGXX, to
get yourself in the right position relative to a field.
You can also get the nearest airfields with frequencies
and runway lengths out of the database and go direct
to them.
The Garmin will attempt to fly a from/to track between points
and let you know how far off track you are in a VOR-like
fashion, alternatively you can deliberately go off track to
avoid some hazard and then go direct to your waypoint from
your current direction.
I personally work my flight out on the map at home, generate
the waypoints and a flight plan and then load them up into
the aircraft at runup time...you can also store flight plans
and invert them for coming back...
Okay, I'd better stop now, they are very nice pieces of kit,
