Chapter 20. Air Traffic Service Routes

Section 4. Jet Routes

20-4-1. 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.

20-4-2. 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.

20-4-3. 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.
