AREA NAVIGATION (RNAV) "Q" ROUTE SYSTEM
(HIGH ALTITUDE ENROUTE CHARTS)
The FAA has adopted certain amendments to
Title 14, Code of Federal Regulations which paved the
way for the development of new area navigation (RNAV)
routes in the U.S. National Airspace System (NAS).
These amendments enable the FAA to take advantage
of technological advancements in navigation systems
such as the Global Positioning System (GPS). RNAV
"Q" Route MEAs are shown when other than 18,000'.
MEAs for GNSS RNAV aircraft are identified with a "G"
suffix. MEAs for DME/DME/IRU RNAV aircraft do not
have a "G" suffix. RNAV routes and associated data
are charted in aeronautical blue. Magnetic reference
bearings are shown originating from a waypoint, fix/reporting
point, or NAVAID. Joint Jet/RNAV route identifi-
cation boxes will be located adjacent to each other with
the route charted in black. With the exception of QRoutes
in the Gulf of Mexico, GNSS or DME/DME/IRU
RNAV are required, unless otherwise indicated. Radar
monitoring is required. DME/DME/IRU RNAV aircraft
should refer to the A/FD for DME information. Altitude
values are stacked highest to lowest.
