I'd need to spend some serious time to get my head around these
possibilities. Do you Americans go on a GPS training course? I went on
a Honeywell one in 2002 but they never covered these "real life"
procedures. They just went through what the thing does.

Education is seriously lacking. There are a lot of pilots flying behind these
boxes who can't get beyond GO-TO. Good luck finding an instructor who really
knows. Of course the knowledge is to a great extent model specific. Knowing how
to use a Garmin tells you little about how to use a B-K. It's a mess. There are
a few instructors who specialize in this kind of instruction, but you have to
look for them.

Standby for a series of instructors to post "hire me, I know how to do it".
