Which of the following authorizes ATC to clear a tanker to a common receiver altitude without an ALTRV request?

The correct choice pertains to the concept of MARSA, which stands for "Military Authority Responsible for Separation of Aircraft." Under MARSA, the military authority assumes responsibility for maintaining separation between military aircraft, which allows for operations that may not follow the standard air traffic control (ATC) procedures. This includes the ability to authorize a tanker to clear to a common receiver altitude without needing a separate ALTRV (altitude reservation) request.

In scenarios involving MARSA, military aircraft can operate more flexibly and efficiently, particularly during refueling operations, where multiple aircraft may need to use the same altitude simultaneously. The authorization granted under MARSA enables these operations to continue without the usual procedural requirements that apply to non-military operations, streamlining the process and enhancing mission effectiveness.
