IFR GPS's are getting inexpensive enough so that it's becoming a moot
point anyway. Why not just get a used King KLN89 and get it certified
and you will have all you legally need to file /G, no questions asked.
Then use your handheld as a backup to that unit, if it fails. And as a
backup to that unit if there is any ambiguity on the integrety of the
signal. If both units don't agree, there is a problem. If one unit
fails and the other doesn't that tells you its the unit and not the
satellites etc. For full safety you need two units anyway. The reason
why most IFR aircraft have two VOR's, not one. Safe IFR flight is all
about having redundancy. A handheld gives good redundancy to a built in
unit.

Stay safe!


Renters don't have the option of installing IFR certified GPS units in the
aircraft they fly. As the next best option, I bought an Airmap 2000C.
