Section 4. Jet Routes
routes extend from FL 180 to FL 450, inclusive, and are
designated to indicate frequently used routings. Jet routes
may also be designated for route continuity where such
designation would clearly facilitate description of the
intended route of flight.
“T" class NAVAIDs (e.g., TVOR) must not be used to designate
20-4-2. NAVAID SPACING
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., GPS) and
frequency protection afforded for the distance required.
20-4-3. JET ROUTE WIDTH
routes have no specified width however, alignment should be
planned using protected airspace specified for VOR airways
in FAAO 8260.3, TERPS, or any flight inspection limitation
to prevent overlapping special use airspace or the airspace
to be protected for other jet routes.
