This disclosure is directed to systems and methods for aircraft collision avoidance with speed-based collision alert time thresholds. In one example, a system is configured to determine predicted trajectories for an own aircraft and a target aircraft. The system is further configured to determine whether a violation of protected airspace is predicted between the own aircraft and the target aircraft. The system is further configured to determine whether a predicted time to closest approach between the own aircraft and the target aircraft is less than an alert threshold time based on a speed of the own aircraft. The system is further configured to generate an alert output, in response to determining that a violation of protected airspace is predicted and that the predicted time to closest approach between the own aircraft and the target aircraft is less than the alert threshold time based on the speed of the own aircraft.

Collision avoidance system for high-performance non-commercial aircraft

A method of a Traffic Alert and Collision Avoidance System (TCAS), includes the step of utilizing an MID Subfield for a TCAS Broadcast Interrogation Message that is different than a Mode S address assigned to the own aircraft, the aircraft on which a TCAS is installed. A Traffic Alert and Collision Avoidance System includes a TCAS processing unit that performs a method including the step of utilizing an MID Subfield for a TCAS Broadcast Interrogation Message that is different than a Mode S address assigned to the own aircraft.
