PERFORMANCE-BASED NAVIGATION PROCEDURES
Continued from page 49
The FAA is preparing to publish 225 more PBN
procedures in three more metroplexes, including:
* 126 at Southern California
* 68 at Atlanta
* 31 at Charlotte
In addition, Cleveland-Detroit is in the evaluation
phase, while South Central Florida, Denver, and Las
Vegas are in the design phase.
Denver is already using a network of RNAV STARs
developed before it became a metroplex site. These
STARs have enabled RNAV (RNP), also known as RNP
authorization required, approaches to runways since late
2013. For several years, the airport has averaged more
than 1,000 RNP approaches per month.

Core 30 Airport
One of the FAA's highest-priority PBN efforts focuses
on 11 metroplexes - metropolitan areas where crowded
airspace has to serve the needs of multiple airports.
PBN departure, arrival and approach procedures in these
metroplex areas are already providing great benefits in
congested terminal airspace.
The FAA has published many RNAV STAR
procedures with OPD capability at metroplexes that
enable aircraft to achieve greater fuel efficiency by
flying closer to the airport before starting a continuous
descent, which eliminates fuel-burning level offs. OPDs
can be flown when available and when pilots are able to
use them.
The FAA has worked closely with the NextGen
Advisory Committee, a federal advisory committee
composed of aviation stakeholders, to set
implementation priorities. Through this collaboration,
the FAA has completed PBN work in four metroplexes:
North Texas: 67 PBN procedures
* 32 RNAV STARs
* 29 RNAV SIDs
* 6 RNP approaches
Washington, D.C.: 49 PBN procedures
* 24 RNAV STARs
* 25 RNAV SIDs
Houston: 46 PBN procedures
* 20 RNAV STARs
* 20 RNAV SIDs
* 6 RNP approaches
Northern California: 44 PBN procedures
* 17 RNAV STARs
* 19 RNAV SIDs
* 8 Q-routes

EoR Curved Approach
A new FAA Established on RNP rule allows controllers at
Denver to instruct pilots to make a U-turn much closer to the
runway (orange) than with legacy procedures (blue). The
aircraft experiences all the benefits of flying a shorter path.

Denver uses RNP approaches that provide aircraft
flying opposite the direction of landing a new method
for making a U-turn to line up to land. Before RNP,
controllers monitored an aircraft on radar and gave
pilots a series of headings as they turned to join other
aircraft already lined up on a straight-in approach to the
runway. Before an aircraft under radar contact could
start to turn, however, controllers had to be sure it would
remain separated 3 nautical miles laterally or 1,000 feet
vertically from other aircraft. This led to aircraft flying
as many as 20 nm away from the runway before a U-turn
was possible.
Now, due to an Established on RNP rule change by the
FAA in 2015, an aircraft can be considered established
on a precisely defined, curved approach procedure with
the required separation from other aircraft before it
begins its U-turn to the runway. The EoR technique has
enabled controllers to use curved RNP approaches more
often at Denver. EoR shortens the path each aircraft
