Hello, guys!Recently I was flying an approach to KSNA (John Wayne-Orange County Intl.) on the POSKY Boeing 737-700. However, I noticed than when I pressed on the APPR button (default 734 panel), both ALT and HDG selectors turned off even without the GS signal being recieved. Actually, after another try, I realized the autopilot only tracks down the localizer but doesn't obey to the GS no matter its position with reference to the plane (you might be flying under the GS or over it and the autopilot wouldn't care at all). In the end, I had to descend manually all the way to the runway...(fortunately, the autopilot did follow the LOC guidance).How can I fix this so I can tune it for tracking both the LOC and the GS??Thank you!!

Couple of suggestions:- make sure that the NAV/GPS selector is set to NAV, or the autopilot will not detect localizer or glideslope- always intercept the localizer first, and approach the glideslope from beneath.Hope this helps.;)

Well, this is weird now. Perfoming another approach to KDAL, the Autopilot worked fined all the path to the rwy. Perhaps I was doing something bad the last time...Thanks

Have you checked to see if your KSNA runway has a glideslope?My info on KSNA shows an ILS approach only for 19R.Regards,JerryH

Well, in that time I was perfoming the ILS approach..(conffirmed by FsNav)

Be aware that FS Nav displays localizer back course approaches on the map, by default. There is a checkbox in the settings that can turn this feature off.What runway were you landing on? In the real world, KSNA has both an ILS and an LDA (a form of offset localizer) on Runway 19R. If you were landing on Runway 1L, you were probably receiving the back course.Todd
