    Unhappy Aircraft turning in towards waypoints when very close

    I've recently started having a problem with the Boeing suite. When the aircraft is approaching a waypoint as it gets close it starts to turn in towards it. Then, as it passes over it the aircraft has to change heading for the next waypoint.

    This happens even when the two waypoints are in a straight line. It's like the next waypoint isn't being detected early enough.

    This problem is quite new and I'm struggling to work out what could be wrong. I know other software has a 'fly-over' option where the aircraft would not turn until that waypoint had been reached. But in PM I'm pretty certain it would switch to the next waypoint when within a mile or two so as not to cause this 'turn in' problem.

    Anyone else experienced it and do you know how to resolve it?

    Thanks.

    Hi Ray,

    I encounter a relate issue. My case is my plane fly 2 different circles (follow the mistake on CDU flight plan) when leaving an airway waypoint (no flyover) and making a left turn to the next waypoint (1x dme away). I know this problem since I am doing the flight plan on ground. I was thinking it will be solve when reaching there and end up it didn't. I wonder if this is caused by the new nav data.

    I should take picture next time when doing that flight.

    By the way, what version of CDU and AIRAC are you using when having this problem?

    This phenomenon has always been there for as long as I have PM (years) .

    At the time it was "agreed" that it was a YAWDAMPER problem because some simmers could avoid it by switching on the yawdamper.

    I have never been able to avoid this "swirling" around a waypoint.
    Even with pmSystems fully operational, it still happens.

    Its annoying only if you fly full auto.

    Exclamation

    I have contacted PM directly for this. I have not seen this behavior in a long time in PM. My CDU flies as it should. No swirling around the way points in fact at times it flies a few miles to the left or right of the way point to stick to the flight plan! I am using an older beta for the CDU and the last beta Navdata. Will let you know what I find out.

    I have heard from Enrico and he is traveling. He will look into this when he is back home next week. I will try to run a few more tests myself tonight and see if I see this behavior.

    Gents,

    This problem arises ocasionally, on my set up, when there is very strong 100kts or more cross wind only, as it seems the plane is "crabbing" to catch the waypoints.

    for the rest in calm winds i have not had this problem for years

    Hi Alkit,

    I'm running build 384 of the CDU but still using the old datafiles from last year. I think the problem is more to do with the CDU.
