Hello all you GPS geniuses,
Question: How do you get vertical guidance in an LPV approach when there is no glideslope like with an ILS system?
thanks.

The glideslope is generated from the 3d GPS position, and displayed on the same CDI that you use for the ILS.

The same way you get horizontal position without a localizer. The GPS gets distance from multiple satellites to calculate a position.

You can load/activate it in approach mode/ runway selection on the GPS, GS indicator will be alive as soon as you switch it to GPS from VLOC (very important: it wont work if you leave it on VLOC mode) during approach. Of course, there must be an outlined LPV app in the GPS database, otherwise GS indicator wont be alive.

And goes without saying, but you need an installation that is WAAS certified (TSO C146a) to be able to use this magic system
