04/001 - WAAS LPV WAAS LNAV/VNAV OTS WIE UNTIL UFN

This Notam has been posted, well, since April.


Sorry I haven't replied sooner but the NOTAM was canceled on the 7th.

Just a few clarifications on WAAS notams, which are actually explained
in the chapter 1 section 1 of the AIM. WAAS unavailable NOTAMs
indicate loss or malfunction of the WAAS system. In flight, Air
Traffic Control will advise pilots requesting a GPS or RNAV (GPS)
approach of WAAS unavailable NOTAMs if not contained in the ATIS
broadcast.

WAAS unreliable NOTAMs indicate an expected level of service, e.g.,
LNAV/VNAV or LPV may not be available. In flight, Air Traffic Control
will not advise pilots of WAAS unreliable NOTAMs, and they are
generally not offered by FSS unless requested.

When the approach chart is annotated with the inverse W (not inverted
W, Jon! That's an 'M' ha!), site-specific WAAS unreliable NOTAMs or
Air Traffic advisories are not provided for outages in WAAS LNAV/VNAV
and LPV vertical guidance.

Safe flights!

Yes, thanks. I noticed the cancellation. And the information you post
from the AIM is the same as was posted in guidance back in 2003. As you
note by omission, OTS is not described with regard to a WAAS NOTAM.
