Mxsmanic,

But that's just it: There are few ground features shown on the chart.
In some cases, a charted feature is near the border of the airspace,
but in many cases there is nothing along the border. Even with
landmarks, the best you can do is estimate.


You know yourself how many times you've been told this here, but in a
real plane, this is a non-issue - as you would find out from one hour in
the air. Orientation by ground features is a very basic piloting skill
which is acquired during basic instruction. It works very well most of
the time for most pilots - and should you get lost, there are strategies
to find your position again. But, GPS moving maps have made it easier.
The consequence of using one is that you will pass a restricted airspace
much closer than you would using ground features because you will be
able to determine your location more precisely. If, OTOH, you're in
doubt, you'll just give the restricted airspace a wider berth.
