KAP140 APR GS locking issue

Postby benih » Tue Oct 16, 2018 10:18 pm

Hello,
i recently did some unrelated tests regarding IFR conditions and tried the c182s autopilot APR mode.
The NAV1 did not have a valid GS signal yet, however it locked the GS. I had expected that the GS only locks if there is a valid signal.

This may also effect the c172p, because i used its code about a ear or so.

Details here: https://github.com/HHS81/c182s/issues/302
I would be glad if someone more knowledgeable could help here...

Which KAP140 is this? We have a newer versionKAP140 in a branch on the dev repository. If you get a chance would you mind checking it out and seeing if it has the same fault? We think it has other issues (still tuning) but I would like or know whether this is also something that may need fixed.
I would do it myself but haven't been educated enough on ILS approach.

Its the default one in FGData, and yes, the new cessna 172p KAP140 is affected too (but the fix fixes this for her also).
