The performance of a state vector conflict probe (utilizing only position and velocity vector information) is analyzed. A methodology is presented for determining missed and false alert rates as functions of look-ahead time. A simple deterministic conflict probe, similar to that used for short term conflict alert in current air traffic operations, is implemented – it simply projects the velocity vector forward from the current position.
