Probably this has been answered in this forum previously, but I can't find
it. Sorry.
I recently got into a friendly discussion with a knowledgable CFII who
said
a Garmin 430 could not be legally used as "sole means of navigation".
Looking back, I think what he means is that "GPS" (even IFR certified
units)
can not be used as sole means. Since the Garmin 430 contains not only
TSO'd
GPS but also VOR, LOC, GS, etc., my position is that this unit (without
any
other navigation equipment on board) is legal as a "stand alone" for use
en
route, terminal, and approach . (I know charts are still necessary.)
Please advise.
The pressure altitude input and operator input baro correction, such as the
new UPSAT unit, will be a requirement for "sole means".
