Yes WAAS takes care of the integrity requirement.

Even on a handheld like the Garmin 296/396 models?


Because it is a VFR unit, you have no assurance that the method by which
the 296/396 employs WAAS provides the required integrity.

Unless Garmin has a presence on this forum, no one can answer your
question with much of anything other than opinions.

The folks are Garmin who engineer the aviation handhelds are part of the
same group that make GPS units for hikers, automobiles, etc; i.e. what
Garmin calls the "Consumer Products" group.


Thanks Sam. Hopefully one of my responses was not misleading. WAAS
does make up for aviation integrity requirements that are not designed
into current GPS satellites. But for IFR flight, it assumes the
proper user equipment as well (I forget the applicable TSO).
