Hello FSDT.
I understand that a new AFCAD is being designed for ORD with tweaks to fix some issues. I was wondering if it would be possible to reduce the amount of nodes at turns and intersections.
I looked at the AFCAD and saw that there are nodes used to make the taxi line in AFCAD follow the actual taxiway centerline in the airport. The problem I've found with this in AF2s I've made is that aircraft make their nosewheel follow the line, often taxiing onto the grass/shoulder (especially pronounced with long aircraft like the B744, B773, and A346).
By simply placing the nodes in the middle of the intersection, or the corner of the turn, the aircraft make the turn more accurately and with all wheels on the pavement.
Hopefully what I've said makes some sense, it is kind of hard to describe. If need be, I can try and post some pics of what I'm trying to say.
