Aircraft turning in towards waypoints when very close

[Ray Proudfoot]

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.

Hi Tony,

This is a new problem for me. And as I switch on the MCP quite soon into the flight it's something I can't live with. I will revert to an earlier version of the CDU and if it goes away then it must be related to the more recent build.

More later.

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.

Hi Bob,

Thanks for all your work on this. I'm going to revert to an earlier build of the CDU (382) and see if it resolves it. That should help Enrico.

Cheers.

I've switched back to 382 and the problem went away. Seems pretty conclusive it's something to do with 384. Hopefully Enrico can find the glitch and resolve it.

Thanks to all involved.

What Jonathan said was they are changing the way the CDU works internally and it may have something to do with that. Enrico will look into it when he gets back next week.

Thanks Bob. At least I have 382 until the fix is issued.

Thanks Peter. I've installed it and will try it tomorrow.

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 guys,
Even the real aircraft does that from time to time!

So software glitches aren't confined to the world of simulation!

Yes, that's resolved the problem, thanks.
