Afs/avidyne LPV glide slope

Help please!

I know it displayed before. But I cannot get it now.

AFS5500 and an Avidyne 440. Selected an rnav gps 5 approach to kbct. I get lateral position but I do not get a glide slope.

Approach selected and activated. Waypoints sequence. Start at 2000 feet. Map displays properly. Flight plan on the afs and 440 all show properly. LPV on the 440 displays. Fly into the approach and the glide slope does not come up.

I have looked at the afs pilot guide and do not get help.

Suggestions appreciated.

Are you intercepting from below? I’ve found it won’t appear if you’re intercepting from above, ie high at the intercept fix.

Is this an LPV Approach?
