What is a Route established below the coordination level to facilitate the movement of Army aviation assets; it is normally located in the corps through brigade rear areas of operation and does not require approval by the airspace control authority?

• A. BDZ Base defense zone
• B. LLTR Low Level Transit Route
• C. MRR Minimum-risk route
• D. SAAFR Standard-use Army Aircraft Flight Route

Answer: (D)

A Standard-use Army Aircraft Flight Route is a route set up below the level of formal airspace coordination to move Army aviation assets efficiently. It’s typically laid out from corps through brigade rear areas, allowing routine flights to proceed without needing explicit approval from the airspace control authority. This arrangement speeds movement, reduces administrative delays, and keeps aviation operations within pre-coordinated corridors that are already approved for Army use.

Base defense zones, which are security perimeters around a base, don’t describe a flight routing system. Low-Level Transit Routes are specific low-altitude paths, but they’re not the standard-use, no-approval-from-airspace-control arrangement. Minimum-risk routes are designed to minimize risk to people on the ground, but they don’t capture the concept of a routinely pre-approved, lower-echelon routing that bypasses airspace control authority for Army aviation movements.
