Yes ,you are right ,but that is the basic rules ,sometimes that rule may not work
Could you give an example?
It seems that we need to establish a matmatics model and calculate the wind speed ,IAS etc ,then we can give a better resolution.
Consider the fact that a given wind will affect two aircraft in close proximity, to virtually the same extent.
"If it ain't broken" comes to mind. And be very very very
very careful about trying to outsmart TCAS. Others have done it before, and some of them are not here anymore.
