What best describes a Military Training Route (MTR)?

• A. An airspace with defined vertical and lateral limits used for military training at airspeeds over 250 KIAS.
• B. A controlled airspace with altitude minimums for instrument approaches.
• C. An area where only VFR traffic is allowed.
• D. A route for commercial jets only.

Answer: (A)

Military Training Routes are airspace segments created to let military aircraft train at high speeds within clearly defined lateral and vertical boundaries. The key point is the combination of designated routes and the speed threshold—training at speeds over 250 knots indicated—so civilian pilots know where high-speed military activity may be taking place and how to avoid or coordinate with it. These routes can be flown under either IFR or VFR depending on the segment (IR for instrument flight rules, VR for visual flight rules), and they are published on charts. They are not limited to VFR traffic, nor restricted to commercial jets, and they’re not primarily about instrument approach minimums.
