What are MTRs primarily used for?

MTRs, or Military Training Routes, are primarily designated for military aviation training exercises. They allow military aircraft to operate at low altitudes and high speeds while training, ensuring that pilots can effectively practice various maneuvers in realistic environments. These routes help maintain operational proficiency and readiness among military personnel.

It’s important to note that while commercial airlines and cargo operations may utilize specific airspace, MTRs are specifically tailored for military use. Similarly, search and rescue missions, though critical, do not fall under the primary function of Military Training Routes. The unique nature and purpose of MTRs make them essential for the military's training and operational needs.
