Section 4. Jet Routes

  1. DEFINITION
  1. Jet routes extend from FL 180 to FL 450, inclusive, and are designated to indicate frequently used routings. Jet routes are not designated above FL 450 due to navigation aid service volume limitations and frequency protection issues.
  2. Unless otherwise specified, the names appearing in jet route descriptions are the names of VOR or VORTAC navigation aids. DME fixes and latitude/longitude coordinates are not used in jet route descriptions.

NOTE-

Terminal class VOR (TVOR) NAVAIDs must not be used to designate jet routes.

  1. NAVAID SPACING

Jet routes are normally based on “H" class NAVAIDs spaced no farther apart than 260 NM or non-VOR/DME area navigation system performance. They may be based on more widely spaced NAVAIDs if a usable signal can be provided (e.g., expanded service volume) and frequency protection is afforded for the distance required.

  1. JET ROUTE WIDTH

Jet routes have no specified width; however, alignment should be planned using protected airspace specified for VOR Federal airways in FAA Order 8260.3, United States Standard for Terminal Instrument Procedures (TERPS), or any flight inspection limitation to prevent overlapping special use airspace or the airspace to be protected for other jet routes.
