Is there some additional selection i have to make to get a GS/VNAV vertical path indication on my 106A indicator when conducting an RNAV GPS LPV approach? I have even begun searching the manual, but so far have only found a reference to check Advisory glideslope ON in AUX, user options. And, not even sure if that affects the indicator. I hope something isnt wired incorrectly. I do get GS indications when doing an ILS approach.

Joe, if memory serves some pilots do not like or want the advisory glidepath and they asked Avidyne to make it a User On/Off item. I believe Avidyne complied so you will need to turn Advisory Glidepath On somewhere.

Advisory glidepaths at some airports have been known to be a problem if one was to follow them strictly to the airport. They could place one below an MDA at given fix or leave one with unsafe terrain separation.

Always make sure you adhere to the approach plate MDA's on such an approach and that you don't leave the MDA until you've got the airport in sight.

Regards, Jim
