John,

Option 3 sounds like it would work, except for this plan to work
effectively. It would have to be mounted and running at all times.


Some people think it foolish to venture into IMC without some kind of
back-up nav device running along independently of on-board systems. A
handheld GPS qualifies just as well as a running PocketPC/GPS system.
