Chuck,

we were told that GPS was not certified for
use in aircraft, although they do make a good *aid*.


Total BS, I'm afraid. Even the use of handheld GPSs is allowed. And
then there are certified GPS units which are installed in the panel.
Some are certified for VFR only, some for IFR enroute, others for IFR
approaches. There are hundreds of GPS approaches, possibly thousands.
And then there's WAAS, too, which enhances GPS precision. Rolled out by
the FAA this year.
