Question 1

What are Military Training Routes (MTRs)?

Answer 1

MTRs are routes established for low-altitude, high-speed military flight training, generally below 10,000 feet MSL at airspeeds in excess of 250 knots Indicated Air Speed.

Question 2

How are MTRs depicted on charts?

Answer 2

MTRs are depicted in brown on IFR Enroute Low Altitude Charts and are not shown on inset charts or IFR Enroute High Altitude Charts.

Question 3

What types of MTRs are depicted on IFR Enroute Low Altitude Charts?

Answer 3

All IFR Military Training Routes (IRs) and VFR Military Training Routes (VRs) are depicted, except those VRs entirely at or below 1,500 feet AGL.

Question 4

How are MTRs identified?

Answer 4

MTRs are identified by designators (e.g., IR-107, VR-134) shown in brown on the route centerline.

Question 5

What do the arrows on MTRs indicate?

Answer 5

Arrows indicate the direction of flight along the route.

Question 6

How is the width of an MTR represented on a chart?

Answer 6

Route segments with a width of 5 NM or less are shown by a .02” line; segments greater than 5 NM are shown by a .035” line.

Question 7

How are MTRs tabulated?

Answer 7

MTRs for particular chart pairs are alphabetically, then numerically tabulated, including MTR type, unique identification, and altitude range.
