Hi Guys,

 

Does anyone tried to use Flight One GTN750/650 shoot the GPS approach in Citation, I was trying to shoot GPS approach in KFAT, I pre-select  GPS(LPV) 29L approach which gonna give me vertical guidance generally but this plane may not work properly,so I disconnect A/P after passing FAF,then I hear Glide Slope Warning when I try to descent as normal, I realize the vertical guidance may work so I landed then tried another approach, active the APP mode after start my initial approach point, this time the VSI started to move back and forth, the plane is totally not stable, plane descent over 1500fp and terrain warning occurs, I have to disconnect A/P manually approach.

 

My question is where the Glide Slope indicator come from in the PFD when I shoot GPS approach? There is no ILS signal on that runway so I just confused, second question is how to mute the G/S warning when shoot GPS approach ,thanks !

I have and it does a beautiful GPS approach when you get up to the right altitude for the approach or the glideslope warning will go off
