Lear 35 LPV/LNav approaches with TCN 750

[BobP 56]

Hi,

I understand the LNAV/VNAV approaches are made in the GPS mode. Should the 'Glide Slope' be armed to capture? I have tried a couple GPS approaches and the glide slope is active but the AP does not follow the glide slope descent commanded by the GPS. Thank you in advance.

Hi Bob,

Yep - you should have Glide Slope armed... I don't know your experience - so no offense if you already know - some GPS approaches have vertical guidance and others do not - are you sure the GPS approach you are flying is a precision GPS approach with vertical guidance ???

My home airport (KMSV) has a precision GPS approach on 15 (glide slope) - while the other end 33 is non-precision (no glide slope) - both being GPS/RNAV approaches...

I haven't tried the 2.9 release yet - so theoretically there could be a new issue we're not aware of yet... If so inclined - maybe as a test try the GPS/RNAV/LPV into 15 at KMSV as I've flown it countless times with 2.8 and it worked every time... I usually hit the glide slope capture button when aligned on the final approach course...

Regards,

Hi Bob,

Tested version 2.9 - all appears to be working as advertised - good glide slope capture...

Hi Scott,

Thank you for the reply, I was aware of the Approach requirements and may have misread the plate. Thanks.
