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

Geospatial-Intelligence Agency (NGA) Products
e. The FLIP contains charts and narrative

descriptions of these routes. To obtain this

publication contact:

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.

3-5-3. 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


b. The purpose for establishing a temporary
flight restrictions area is to:

1. Protect persons and property in the air or on

the surface from an existing or imminent hazard

associated with an incident on the surface when the
presence of low flying aircraft would magnify, alter,
spread, or compound that hazard (14 CFR
Section 91.137(a)(1));

2. Provide a safe environment for the operation

of disaster relief aircraft (14 CFR Sec-

tion 91.137(a)(2)); or

3. Prevent an unsafe congestion of sightseeing

aircraft above an incident or event which may
generate a high degree of public interest (14 CFR
Section 91.137(a)(3)).
