(User) Problem with heading after LNAV

Featured Replies

Hi, Today I took the NGX for a short hop on IVAO. Everything went very well until the Controler gave me vectors.I dialed in 180 and hit the HDG button and prompt the plane changed towards that heading. After wings level the plane flew at heading 186. So I dialed in 174 to correct that problem. Then I was supposed to turn on heading 330. I dialed in 324 because it tougt the problem was also noticable here. But then the plane was on heading 325 as the ND showed. So I finaly turned in 329 and I the plane flew heading 330. I don't want to say that this is a bug of the NGX. Migth it is a fail of mine. Like in the MD 11 you can change the ND between HDG and TRACK. I think that could be the problem, because I noticed a green TRACK beside the wrong heading.But how to switch back the ND to HDG mode? Jonathan Huschle

After 50 minutes of flight? Hmm, maybe a cheap one.

Have you installed any of the hotfixes? There was an issue with HDG SEL no longer following mag heading, but instead following track after Lnav was engaged previously. Happens I think all the time. Then your heading will appear to be different then the one commanded. Latest hot fixes should have this fixed. (not just the CTD/freeze issues) Marcus Jian

Well if you have installed it and still experiencing problems, then I don't think I can help. A while ago a hdg track issue was brought up and i think a few users including me submitted a ticket. It appears fixed in the latest hotfixes. Previously I was able to reproduce the bug 100% by simply activating Lnav then Hdg sel.
