4-4-2 ROUTE STRUCTURE TRANSITIONS
To effect transition within or between route structures, clear an aircraft by one or more of the following methods, based on NAVAIDs or RNAV:
Vector aircraft to or from radials, courses, or azimuths of the ATS route assigned.
Assign a SID/STAR.
Clear departing or arriving aircraft to climb or descend via radials, courses, or azimuths of the ATS route assigned.
Clear departing or arriving aircraft directly to or between the NAVAIDs forming the ATS route assigned.
Clear aircraft to climb or descend via the ATS route on which flight will be conducted.
Clear aircraft to climb or descend on specified radials, courses, or azimuths of NAVAIDs.
Clear RNAV aircraft between designated or established ATS routes via random RNAV routes to a NAVAID, waypoint, airport or fix on the new route.Provide radar monitoring to aircraft transitioning via random RNAV routes.
EXCEPTION. GNSS-equipped aircraft /G, /L, /S, and /V on point-to-point routes, or transitioning between two point-to-point routes via an impromptu route.

4-4-3 DEGREE-DISTANCE ROUTE DEFINITION FOR MILITARY OPERATIONS
EN ROUTE
Do not accept a military flight plan whose route or route segments do not coincide with designated Air Traffic Service routes or with a direct course between NAVAIDs unless it is authorized in subparagraph b and meets the following degree-distance route definition and procedural requirements:
The route or route segments must be defined in the flight plan by degree-distance fixes composed of:
A location identifier;
Azimuth in degrees magnetic; and
Distance in miles from the NAVAID used.
EXAMPLE
“MKE 030025.”
The NAVAIDs selected to define the degree-distance fixes must be those authorized for use at the altitude being flown and at a distance within the published service volume area.
The distance between the fixes used to define the route must not exceed:
Below FL 180- 80 miles;
FL 180 and above- 260 miles; and
For celestial navigation routes, all altitudes- 260 miles.
Degree-distance fixes used to define a route must be considered compulsory reporting points except that an aircraft may be authorized by ATC to omit reports when traffic conditions permit.
Military aircraft using degree-distance route definition procedures must conduct operations in accordance with the following:
Unless prior coordination has been effected with the appropriate air traffic control facility, flight plan the departure and the arrival phases to conform with the routine flow of traffic when operating within 75 miles of the departure and the arrival airport. Use defined routes or airways or direct courses between NAVAIDs or as otherwise required to conform to the normal flow of traffic.
Flight plans must be filed at least 2 hours before the estimated time of departure.
The following special military operations are authorized to define routes, or portions of routes, by degree-distance fixes:
Airborne radar navigation, radar bomb scoring (RBS), and airborne missile programming conducted by the USAF, USN, and RAF.
Celestial navigation conducted by the USAF, USN, and RAF.
Target aircraft operating in conjunction with air defense interceptors, and air defense interceptors while en route to and from assigned airspace.
Missions conducted above FL 450.
USN fighter and attack aircraft operating in positive control airspace.
USN/USMC aircraft, TACAN equipped, operating within the Honolulu FIR/Hawaiian airways area.
USAF/USN/USMC aircraft flight planned to operate on MTRs.
USAF Air Mobility Command (AMC) aircraft operating on approved station‐keeping equipment (SKE) routes in accordance with the conditions and limitations listed in FAA Exemption No. 4371 to 14 CFR section 91.177(a)(2) and 14 CFR section 91.179(b)(1).
4-4-4 ALTERNATIVE ROUTES
When any part of an airway or route is unusable because of NAVAID status, clear aircraft that are not RNAV capable via one of the following alternative routes:
A route depicted on current U.S. Government charts/publications. Use the word “substitute” immediately preceding the alternative route in issuing the clearance.
A route defined by specifying NAVAID radials, courses, or azimuths.
A route defined as direct to or between NAVAIDs.
Vectors.
NOTE
Inform area navigation aircraft that will proceed to the NAVAID location of the NAVAID outage.
4-4-5 CLASS G AIRSPACE
Include routes through Class G airspace only when requested by the pilot.
NOTE
1. Separation criteria are not applicable in Class G airspace. Traffic advisories and safety alerts are applicable within Class G airspace to aircraft that are in direct communication with ATC. 2. Flight plans filed for random RNAV routes through Class G airspace are considered a request by the pilot. 3. Flight plans containing MTR segments in/through Class G airspace are considered a request by the pilot.
REFERENCE

4-4-6 DIRECT CLEARANCES
Unless operational necessity dictates, do not issue a routing clearance that will take an aircraft off of its flight plan route if:
The aircraft is part of a known traffic management initiative.
The part of the route under consideration for the direct routing is within a protected segment. If a flight routing within a protected segment is amended, coordination must be accomplished as follows:
ATCS: with TMU.
Terminal facility TMU: with overlying ARTCC TMU.
ARTCC TMU (for amendments outside their facility): with ATCSCC.
EN ROUTE. Do not issue revised routing clearances that will take an aircraft off its flight plan route past the last fix in your facility's airspace, unless requested by the pilot or operational necessity dictates.
NOTE
Nothing in this paragraph must preclude a controller from issuing a routing clearance that conforms to a letter of agreement or standard operating procedure within their own facility or between facilities, is required to maintain separation or comply with traffic flow management initiatives.
