I agree with the previous writer. SCREEN B is great, mainly because it's so intuitive a depiction.

I fly in a very busy environment (within 7 miles of ORD and near at least 6 other corporate type airports) and I almost always have 3 targets depicted. SCREEN B allows me to take a quick glance and understand immeadiatly the traffic picture around me.

I have previously suggested to ZAON that they should try to figure out a way to make the "primary" target depicted stand out from the other two targets. Since color is not an option my suggestion would be to increase the size of the primary target.

ZAON said that they will look into possiblity of making the primary target appear different from the other targets.

I look forward to that revision and I will be the first to send mine in for that type of enhancement.
