Route Use

Clear aircraft via routes consistent with the altitude stratum in which the operation is to be conducted by one or more of the following:

1. Designated ATS routes.
2. Radials, courses, azimuths to or from NAVAIDs.
3. Random routes.
   1. When not being radar monitored, GNSS-equipped RNAV aircraft on random RNAV routes must be cleared via or reported to be established on a point-to-point route.
      1. The points must be published NAVAIDs, waypoints, fixes or airports recallable from the aircraft's navigation database. The points must be displayed on controller video maps or depicted on the controller chart displayed at the control position. When applying nonradar separation the maximum distance between points must not exceed 500 miles.
      2. Protect 4 miles either side of the route centerline.
      3. Assigned altitudes must be at or above the highest MIA along the projected route segment being flown, including the protected airspace of that route segment.
   2. Impromptu.
   3. Point-to-Point.
4. DME arcs of NAVAIDs.
5. Radials, courses, azimuths, and headings of departure or arrival routes.
6. SIDs/STARs.
7. Vectors.
8. Fixes defined in terms of degree-distance from NAVAIDs for special military operations.
9. Courses, azimuths, bearings, quadrants, or radials within a radius of a NAVAID.
10. Fixes/waypoints defined in terms of:
    1. Published name; or
    2. Degree-distance from NAVAIDs; or
    3. Latitude/longitude coordinates, state the latitude and longitude in degrees and minutes including the direction from the axis such as North or West; or
    4. Offset from published or established ATS route at a specified distance and direction for random (impromptu) RNAV Routes.
