Garmin 496 VNAV question

[[email protected]]

1. Are glide-slop informations of LPV & LNAV/VNAV in 496's database?

2. If yes, can VNAV indicators on 496's HSI display this glide-slop
when flying approaches?

Thanks,

Robin

I believe the 496 refuses to give you any sort of glide slope indication
within 500 feet of the ground.

No, I believe the only glide slope is a synthesized vertical descent
profile that is based solely on your GPS altitude and GPS distance from
your target, and I think that is the glide path to 1000' AGL at that.
Furthermore, you can program your desired descent profile to be
something other than the default 500 FPM. The 496 is not intended for
IFR operations, why even the start-up statement says as much.

Answer to #1 is a big no. Lots of complex stuff goes on inside an IFR
WAAAS box to create those glidepaths and, in particular, the LPV path.
The handhelds, not being IFR certified, do not have any of those
capabilities. The VNAV feature in those boxes bears no relationship to
IFR procedures.
