The ______ ACM exists below the coordinating altitude and facilitates the movement of rotary wing Army aviation assets.

• A. SAAFR (Standard Army Aviation Flight Route)
• B. SAAOR (Standard Army Airspace Route)
• C. SAAFAR (Standard Army Airspace Flight Route)
• D. SAAR (Standard Army Air Route)

Answer: (A)

Rotary-wing operations are guided by standardized airspace measures that create predictable, pre-cleared paths to keep helicopters safe and efficient as they move. When you need a low-altitude, rotorcraft-friendly corridor that sits below the main coordination altitude, the measure used is the Standard Army Aviation Flight Route. This route type is specifically designed to facilitate helicopter movement under coordinating altitude by providing defined entry and exit points and a consistent way to navigate busy airspace without conflicting with higher-flying traffic or fixed-wing operations.

The other options refer to different kinds of routes or operate at different altitude bands, so they aren’t the established low-altitude rotorcraft corridors that support Army aviation below the coordinating altitude.
