Traffic coming towards you on the same taxiway is the only time you may experience a problem. That's pretty rare I have to say and indicates someone usually the user has made a wrong turn.
You might 'have to say it' (not sure why) but it's not true at all - I have not made any wrong turn: often there are no wrong turns to make with single taxiways.. As the PF3 pdf itself says, this happens because it is not possible to predict which taxiway AI traffic will use. I quite often have traffic coming at me on the same taxiway, especially at airports which only have one runway. That's FS9 ATC, not PF3.
But
and much more to the point, traffic coming directly at me is NOT the only time I have a problem - that's the point of this thread. I have the problem of traffic stopping, no matter how I try to tweak the settings, when it is going the same way as I am. I don't expect PF3 to be able to control traffic coming head on, for the reasons I gave above. Hence, I am not sure what the point of that specific function of CM is supposed to be.
I've tried lots of different values for the CM - OK I'll give 5 another try, but basically I am sadly going to have to switch it off if I can't stop a/c grinding to a halt in this way.
So I see no need to change it.
No, if it's working for you, I dare say you don't. But, whether you see the need or not, for you, it's a constant annoyance for me having the AI traffic freeze up like this when it's heading in the same direction as I am and at a reasonable distance in front of me: hence I regretfully am going to have to turn CM off as it is creating a situation that is on balance
less realistic than with it switched off. So as I say, I (and am I alone?? If so, it won't happen of course) would really appreciate the option of turning the forward control of CM off, if it's not a difficult tweak to make, via advanced options or whatever) and just have the lateral option working - that works well and I want a/c to stop if they are approaching from the side. I don't want them stopping when we are taxiing to the same runway in an orderly line, it makes no sense.
I will try a low value again and see what happens though..
