CHART CHALLENGE

SALUTING MTRs AND SMARs BY MACHTELD SMITH
YOU'D PROBABLY EXPECT MILITARY TRAINING
FLIGHTS INSIDE MILITARY OPERATIONS areas

(MOAs). But don't forget about military
training routes (MTRs) established below
10,000 feet msl for low-altitude, high-speed (in
excess of 250 knots) operations. Depicted by
gray lines (light brown on en route low-altitude
IFR charts), "IR" routes are ﬂown under
instrument ﬂight rules and "VR" routes are
ﬂown in accordance with visual ﬂight rules.
Take a closer look at the chart: You'll notice
that these routes have numbers-four digits
indicate no segment is above 1,500 feet agl;
three or fewer specify one or more are above
1,500 agl. MTRs can vary in width from four to
16 miles. Flight direction is indicated by a small
arrowhead. Contact ﬂight service to ﬁnd out

about scheduled activity, altitudes, and actual
route width before ﬂying within an MTR.
Some MTRs traverse special military activity
route (SMAR) corridors deﬁned by gray
hashed borders. Ceilings and ﬂoors are shown
in hundreds of feet msl and agl, respectively.
SMARs have a boxed note with a radio
frequency to obtain area activity status.
