ATC facilities shall provide inflight separation unless which of the following is applicable?

• A. Visual separation
• B. IFR separation
• C. MARSA
• D. None of the above

Answer: (C)

The key idea is that ATC normally provides inflight separation, but there is a specific exception when the military takes over that responsibility. MARSA stands for Military Assumed Responsibility for Separation of Aircraft. When MARSA is applicable, the military authorities assume responsibility for maintaining separation between aircraft, so ATC will not provide inflight separation for those flights. This is why MARSA is the correct choice. Visual separation, IFR separation, or none of the above do not describe an exception to ATC providing inflight separation in the same way MARSA does. Visual separation is a method of separating traffic, IFR separation is the standard ATC service for IFR flights, and “none of the above” would ignore the defined MARSA exception.
