Departure/Enroute RAIM

It was a both a typo and a misunderstanding about 146 boxes when I made the
original post. One of my sources pointed out after my initial posting that 146
boxes were good to go absent WAAS NOTAMs.

My purpose of having made the posting was to point out to users of this Usenet
group the onnerous requirements just imposed on most IFR GPS users.

The relevance is that most users with GPS, light aircraft, biz jet, or air

OK, but my comment was solely related to the WAAS boxes.

And, ok, you responded to my comment about the situation that changed a whole
lot yesterday and affects the majority of the GPS-using community; i.e.,
TSO-C129 panel mounts and the high-end FMS/LNAV suites. I don't believe you
started a new thread. ;-)


You are correct that I did not start a new thread. I did not feel it was
warranted when I was correcting your statement about RAIM being required
for TSO 146a boxes.

At least that's what I thought I was doing. However, what you actually
wrote was:

"The practical aspect for light aircraft equipped with either TSO 129 or
146 boxes is that a terminal RAIM check must not be accomplished before
using an RNAV ODP".

I thought you had made a typo -- "RAIM check must not be accomplished..."
should have read "RAIM check must NOW be accomplished..." and that was what
I was responding to.

If it was a typo, then your statement about the 146 boxes was incorrect; if
it was not a typo, then your statement about the 129 boxes was incorrect.

Now that that's cleared up, do you know which equipment suffix should be
used for those with GPS units that are capable of the RNP2 and RNP1
requirements (in order to fly the RNAV SIDS/STARS)? Should we be using /G
or /R (assuming no RVSM)?
