for the blind broadcasts. It is prudent for a pilot to report
on−the−ground or airborne to end the service.
2. RAA service is operated within 10 statute
miles of specified high activity GA airports where a
control tower is not operating. Airports offering this
service are listed in the A/FD and the published
service hours may be changed by NOTAM D. Final
Guard is automatically provided with RAA.
3. Remote Airport Information Service (RAIS)
is provided in support of short term special events like
small to medium fly−ins. The service is advertised by
NOTAM D only. The FSS will not have access to a
continuous readout of the current winds and
altimeter; therefore, RAIS does not include weather
and/or Final Guard service. However, known traffic,
special event instructions, and all other services are
provided.
NOTE−
The airport authority and/or manager should request RAIS
support on official letterhead directly with the manager of
the FSS that will provide the service at least 60 days in
advance. Approval authority rests with the FSS manager
and is based on workload and resource availability.

Towers, Paragraph 4−1−9.
b. It is not mandatory that pilots participate in the
Airport Advisory programs. Participation enhances
safety for everyone operating around busy GA
airports; therefore, everyone is encouraged to
participate and provide feedback that will help
improve the program.
3−5−2. Military Training Routes
a. National security depends largely on the
deterrent effect of our airborne military forces. To be
proficient, the military services must train in a wide
range of airborne tactics. One phase of this training
involves “low level” combat tactics. The required
maneuvers and high speeds are such that they may
occasionally make the see-and-avoid aspect of VFR
flight more difficult without increased vigilance in
areas containing such operations. In an effort to
ensure the greatest practical level of safety for all
flight operations, the Military Training Route (MTR)
program was conceived.
b. The MTR program is a joint venture by the FAA
and the Department of Defense (DOD). MTRs are
mutually developed for use by the military for the
purpose of conducting low-altitude, high-speed

training. The routes above 1,500 feet AGL are
developed to be flown, to the maximum extent
possible, under IFR. The routes at 1,500 feet AGL
and below are generally developed to be flown under
VFR.
c. 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 shall be
5 miles or more; and flights shall 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 shall be identified by four number characters;
e.g., IR1206, VR1207.
(b) MTRs that include one or more segments
above 1,500 feet AGL shall 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 Low Altitude En Route Chart. This
chart will depict all IR routes and all VR routes that
accommodate operations above 1,500 feet AGL.
(b) VFR Sectional 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 DOD primarily for military users
and contains detailed information on both IR and VR
routes.
