My PMDG is working pretty flawlessly. However, once in a rare while the plane will go into a sudden climb after having captured the localizer and glideslope. Most of the time the landings are fine. When this anomaly happens, the only thing I can do is shut the autopilot down completely and finish the ILS landing manually.Has anyone experienced this at all?Lee

Hi Lee,I've heard about some rare occasions here on the forum and I think it has been related to a too low approach speed. Thus the α-floor protection kicking in. Check your speed when this is happening and crosscheck it against your landing weight with someone here on the forum or any real world tables. You also might wanna check any wake turbulence if you are using AS2004. But then the A/P should disconnect and not give you a GA thrust.Hope it helps,

I've had it happen to me a couple of times. twice out of 200 flight hours are an anomaly that I can live with. Like you the only way out of that situation is to turn the autopilot completely off and hand fly it down otherwise it just wants to climb.Willhttp://www.precisionmanuals.com/images/forum/ng_driver.jpg

Guten Tag Lee.Observed the same quite often.Have no explanation. Read nothing in the PMDG Manuals about....the α-floor protection kicking in...My advice: an immidiate further click on the APP button REsets the mode and reinterception of LOC & GP takes place.G

Thanks for the inputs guys. I do agree that it is looking like speed related. Possibly, it may be the reverse, too much speed. I've been trying it lately with getting the plane slowed down a bit sooner and capturing the ILS at 180 or 190 knots, depending on weight, and then settling into 150 or 160, depending on weight, once the glideslope is captured. It seems to be a bit more stable. Also I use max 30 degrees flaps when cleared to land. All of this seems to getting a little better result.It sure is a great product, the 747 will be awesome!Lee
