Generally, MTRs are established below
10,000 feet MSL for operations at speeds in excess of
250 knots. However, route segments may be defined
at higher altitudes for purposes of route continuity.
For example, route segments may be defined for
descent, climbout, and mountainous terrain. There
are IFR and VFR routes as follows:
1. IFR Military Training Routes
−(IR).
Operations on these routes are conducted in
accordance with IFR regardless of weather
conditions.
2. VFR Military Training Routes
−(VR).
Operations on these routes are conducted in
accordance with VFR except flight visibility must be
5 miles or more; and flights must not be conducted
below a ceiling of less than 3,000 feet AGL.
d.
Military training routes will be identified and
charted as follows:
1. Route identification.
(a)
MTRs with no segment above 1,500 feet
AGL must be identified by four number characters;
e.g., IR1206, VR1207.
(b)
MTRs that include one or more segments
above 1,500 feet AGL must be identified by three
number characters; e.g., IR206, VR207.
(c)
Alternate IR/VR routes or route segments
are identified by using the basic/principal route
designation followed by a letter suffix, e.g., IR008A,
VR1007B, etc.
2. Route charting.
(a) IFR Enroute Low Altitude Chart.
This
chart will depict all IR routes and all VR routes that
accommodate operations above 1,500 feet AGL.
(b) VFR Sectional Aeronautical
Charts.
These charts will depict military training
activities such as IR, VR, MOA, Restricted Area,
Warning Area, and Alert Area information.
(c) Area Planning (AP/1B) Chart (DOD
Flight Information Publication
−FLIP). This chart
is published by the National Geospatial−Intelligence
Agency (NGA) primarily for military users and
contains detailed information on both IR and VR
routes.

This NGA FLIP is available for pilot briefings at FSS
and many airports.
f.
Nonparticipating aircraft are not prohibited
from flying within an MTR; however, extreme
vigilance should be exercised when conducting flight
through or near these routes. Pilots should contact
FSSs within 100 NM of a particular MTR to obtain
current information or route usage in their vicinity.
Information available includes times of scheduled
activity, altitudes in use on each route segment, and
actual route width. Route width varies for each MTR
and can extend several miles on either side of the
charted MTR centerline. Route width information for
IR and VR MTRs is also available in the FLIP AP/1B
along with additional MTR (slow routes/air refueling
routes) information. When requesting MTR informa-
tion, pilots should give the FSS their position, route
of flight, and destination in order to reduce frequency
congestion and permit the FSS specialist to identify
the MTR which could be a factor.

3. Temporary Flight Restrictions
a. General.
This paragraph describes the types of
conditions under which the FAA may impose
temporary flight restrictions. It also explains which
FAA elements have been delegated authority to issue
a temporary flight restrictions NOTAM and lists the
types of responsible agencies/offices from which the
FAA will accept requests to establish temporary
flight restrictions. The 14 CFR is explicit as to what
operations are prohibited, restricted, or allowed in a
temporary flight restrictions area. Pilots are responsi-
ble to comply with 14 CFR Sections 91.137, 91.138,
91.141 and 91.143 when conducting flight in an area
where a temporary flight restrictions area is in effect,
and should check appropriate NOTAMs during flight
planning.
