Key Benefits: Access to runways that were previously not feasible due to conflicting operations.

Conflict Resolution: Utilizes new reduced separation standards for approaches at adjacent airports, allowing simultaneous and independent operations.

Example: New approach into Airport Bravo does not cross the straight-in ILS approach into Airport Alpha, reducing the closest point spacing below three nautical miles.

Approach Design Flexibility: Approaches can run parallel or converge before diverging.

Specificity: The two procedures are allowed to be designed to either run side-by-side or come together and then separate again.

Controller Responsibilities: Controllers maintain 1,000 feet vertically or three miles laterally until both aircraft are established on their approach.

Clarification: Once established, controllers no longer need to enforce the 1,000-foot vertical or three-mile lateral separation.

Safety Analysis: The MARS concept is backed by extensive safety analysis including human-in-the-loop simulations for controller actions.

Details: Controllers are authorized to use reduced separation if they can monitor and correct deviations from course as needed.

Separation Standards: Reduced separation is based on two key factors:

Factor 2: Controller’s capability to monitor aircraft conformance and issue corrective actions if necessary.

Initial Focus Area: MARS initially targets de-conflicting approaches within the terminal environment but can be applied more broadly.

Scope: The concept is not limited to a single airport but could be expanded to multiple airports with conflicting traffic flows.

Benefits:

Opportunities*: Opens up a wide range of operational possibilities for airports.

FAA Commitment: The FAA is committed to developing and implementing the MARS concept, aiming to realize its associated benefits.
