WG-75 is tasked to develop Airborne Collision Avoidance Systems (ACAS) X MOPS as a joint RTCA/EUROCAE activity. With ACAS X being developed in various variants, also the work of WG-75 will be organised following this specific structure. ACAS Xa will be the successor of TCAS II and the MOPS will also contain provisions for ACAS Xo designed for specific procedures such as close runway operations. ACAS Xu will provide requirements for a collision avoidance solution for unmanned aircraft. Finally, WG-75 will develop a MASPS defining requirements for the interoperability on collision avoidance systems of different designs.
No meetings scheduled.
