I wonder if it's going to be taken up? No comment so far :) (I have had CM turned off since I last posted in this thread)..

If I may say, I still think you are taxiing too fast!
To what speed is your AI set to for taxiing? You should be about 3 knots below that for security. Generally if you are taxiing at 15kts you should have few conflicts even in a busy enviroment. And don't forget at a real life busy airport it would be foolish to taxi too fast. If there is just you and a single AI in front them let him get ahead and then you can taxi in relative security at 15+kts. It is rarely a problem for me. If AI are already queueing for the runway then abviously I taxi up behind them and wait.
If I see that an AI has stopped in front of me and it appears that's because I'm getting too close I stop and let him move off. And then after a few seconds begin to move off slowly myself.
What happens on motorways when everyone is driving fast and there is some kind of obstruction up ahead. Everyone bunches up and stops. But if variable speed limits are imposed everyone drives slower and often there is no blockage.
The slower you taxi the less problem you will have as you are catching up the a/c in front too quickly. The AI itself is speeding up and slowing down (within its parameters) to go around bends etc. And if you are bombing along at too high a speed problems will occur.

Just wondering Dave whether you had any further thoughts about implementing what I suggested above (July 06 2016) - if it is achievable of course - and have the CM work for aircraft that are at an angle greater than (say?) 5-10 degrees from the direction of travel of the user a/c travel, but not on a/c that are at a narrower angle than that, i.e. directly ahead (and presumably therefore taxiing in front of the user aircraft, en route to the same runway - or to parking).

I have had CM disabled since the last post here as I found it really frustrating having AI traffic on the same taiway putting on the brakes every few minutes for no reason.
Quote:
1. AI in front of me stops
2. I stop
3. AI continues
4. I continue
5. same AI stops again
6. I stop again
7. same AI continues again
8. I wait long enough until the AI is far away enough to not being stopped by CM (400m)
(Thomas describing almost a year ago what I still get)...

Keeping to speeds of under 10 knots at large airports is not I think very practical (it seems like a crawl!): I like to taxi at around 15 kts, except on turns, which is realistic I believe and gets you to where you want to be in reasonable time. FS AI traffic taxis at a 'proper' speed too - around 17kts as far as I recall, certainly not under 10. (According to various real-world aviation sites I have looked at, average taxi speeds for large jets is between 15 and 25 knots....).

I have not really found a ground speed Pause CM value that works (whether it be lower than 10 or higher: higher values end up effectively disabling CM altogether, whilst lower values lead to this continual stop/start behaviour of the AI traffic). I don't think that the CM is properly controllable by the CM pause speed value - if it were possible to implement the suggestion I made on the previous page of this post, wouldn't that solve the problem? Or perhaps, if that's not achievable for whatever technical reason, the 400m radius of CM could be made user controllable? A smaller radius would at least mean you didn't have to follow almost 1/2 kilometer behind taxiing aircraft to prevent them stopping.

Be good to have CM working and avoid situations like my screenshot - my a/c at the front (not sure why FS9 is doing this!!!)

I still get this, too, but still have CM enabled, and learned to live with that.

And I have the CM speed still at 5kts. I don't taxi more than 15kts unless the way ahead is clear. If I perceive that someone ahead of me has stopped then I slow down and stop (if necessary). and wait until the a/c in front has moved on before starting again. It's pretty much as one would behave in real life. You are not going to "race up" to any aircraft. Taxiing too fast is more than 50% of the problem.

We've been down this road before: I am not looking to open up old disagreements. 15kts is not too fast. Period.

I posted again after several months just to ask whether the idea I put forward is actually feasible. Thanks.

I have suggested to Dave that he implement the "On the right - In the right" navigation rule. That is any aircraft on your right that poses a threat is in the right and it is your duty to avoid them. This rule applies both on the ground and in the air. It would mean creating an arc in which all aircraft in that arc would not be affected by the CM. Whereas any other aircraft would be affected and stopped (thus avoiding you). It's "ultra" realistic if it could be implemented. This aviation rule like so many others was transplanted from maritime law.

I can't locate any document which says this. Could you possibly point me to one? Taxiing traffic follow instructions from the control tower, surely? At a really busy airport relying on pilots noticing another aircraft approaching from the right (what if from the right and somewhat behind?) sounds very 'hit and miss' (literally!)! But, as I say, if you can indicate a real-world document that says this, maybe you know better than I do...

I am not sure though that your right-hand idea would address the problem as well as the cone diagram I drew last year. The issue is with AI traffic coming to a halt when they are taxiing directly in front of you. I think most users would like to have a situation where AI a/c stop, rather than run into user a/c from the sides, but do not keep stopping when they are heading in the same direction on the same taxiway. (This does not mean that user a/c should not also be ready to give way to AI traffic when appropriate too, of course).

Thanks.

You will find it in all the pilot training manuals. Irrespective of any ATC directions you must give way to traffic on the right if there is a conflict.
Probably the reason why I don't have your problem is because I taxi according to the rules and in the same manner as I do in reall life.
