OTHER AIRSPACE
Airspace that is not controlled, uncontrolled, or designated special use is categorized as
other airspace.
Military Training Routes
To be proficient, the military services must train in a wide range of airborne tactics
including "low-level" combat tactics. The required maneuvers and high speeds are such
that they may make the see-and-avoid aspect of VFR flight more difficult without
increased vigilance. The military training route (MTR) program is a joint Department of
Defense (DOD) and FAA venture to ensure the greatest practical level of safety for
those flight operations. Additional information concerning MTRs can be found in FLIP
AP/1B.
Military Training Route Definition
Generally, MTRs are established below 10,000 feet MSL for speeds in excess of 250
knots. Routes are developed as follows:
Routes above 1,500 feet above ground level (AGL) are developed to be flown to
the maximum extent possible under IFR conditions.
Routes at 1,500 feet AGL and below are generally developed to be flown under
VFR conditions.
Routes may be established for descent, climb out, and designated mountainous
terrain.
Published Information
MTRs are published in sectional charts, IFR low-altitude enroute charts, and FLIP Area
Planning (AP/1B).
Route Designation
Route designations are shown in Table 6-3.
