Which set of options correctly identifies the participating and nonparticipating aircraft in MARSA separation?

• A. Nonparticipating VFR Aircraft
• B. Civilian Airliners
• C. Participating Military Aircraft
• D. Nonparticipating IFR Aircraft

Answer: (D)

MARSA means the military takes responsibility for maintaining separation in a designated airspace. The aircraft that fall under that arrangement are the ones considered participating, while any aircraft not covered by MARSA in that airspace are nonparticipating. In practice, MARSA separation is focused on IFR traffic, with the military providing the separation for those aircraft that are part of the MARSA arrangement; other IFR flights that aren’t covered by MARSA would be treated as nonparticipating. So the pairing that matches this concept is participating military aircraft as the ones under MARSA control, and nonparticipating IFR aircraft as those not covered by the MARSA arrangement. This reflects that MARSA specifically applies to the traffic within the military’s responsibility for separation, with civilian IFR flights outside that arrangement not participating in MARSA.
