G.R.,

Has the FAA changed it's stance on the use of GPS? Has GPS become
certified
to use in navigation in aircraft?

Yes.


Did it ever HAVE that stance?


From what my instructors in A&P school said, yes, they did HAVE that stance.
Looks as though my instructors were wrong though, huh?

Chill out!

Chuck,

Chill out!


Easier said than done. Guys from that school might be "repairing"
airliners today. Who knows what else they haven't learned. This is
serious stuff...

Yes. About 10 years ago or more.

If a man gets into a fight 3,000 miles away from home, he *had* to have
been looking for it.

I believe, if the unit is certified, that it is good for at least Cat I.

Well...if the unit is certified to SCAT-I (special category I). There has
not been any units in used that is certified to this level. Boeing is
working on one. These are not mere GPS though, they are differential GPS
(with specially designed, dedicated ground station correcting for errors).

WAAS is supposed to take care of the ground station part but so far has not
been good enough for use for CAT-1.
