But why is that different to a visual contact, Phoenix_X? It's just a shape in the distance -- it doesn't have an id-tag attached. At least on TCAS I'd know its level and probably have a better idea of its relative motion
An excellent point
. Except for maybe seeing the a/c type and company, it's not much better than TCAS. I won't argue that!
However, the point remains that thinking you're clear of a TCAS target, may not
A) Mean you're actually clear due to the position error
B) Mean that you're clear of the aircraft that's conflicting with you
At least if you actually see an aircraft point (A) is solved. I agree (B) is not. Thanks for the heads-up!
