I'm not sure how frequently they would want to be using 13L at JFK and 04
at LGA simultaneously, but the case is well demonstrated anyway.

DCA or JFK?



FOR IMMEDIATE RELEASE


AOC 42-05 December 20, 2005
Contact: Alison Duquette
Phone: 202-267-3883 New FAA Navigation Procedure at Reagan National
Helps Travelers, Airlines, Airport Neighbors WASHINGTON, DC —
The Department
of Transportation's Federal Aviation
Administration (FAA) today announced
that a new navigation procedure at
Ronald Reagan Washington National
Airport will increase efficiency,
improve safety, and reduce the effect
of aircraft noise and emissions on
homes and businesses under the flight
path.

Called "Required Navigation
Performance" (RNP), the procedure
takes advantage of a plane's onboard
navigation capability to fly a more
precise flight path into the airport.
The Reagan National RNP approach to
Runway 19, which follows the Potomac
River, allows planes to land with
considerably lower cloud ceilings and
visibility than currently required,
increasing airport access during
marginal weather.

"We're tapping the high-performance
computing capability of today's
aircraft to move more planes more
safely and efficiently," said FAA
Administrator Marion C. Blakey. "The
environmental benefits are terrific
too, because flying straight down the
middle of the flight path means that
people on the ground perceive less jet
noise and experience fewer engine
emissions."

The procedure at Reagan National may
be used by any operator who can meet
specific FAA requirements for aircraft
navigation performance and pilot
training. Alaska Airlines is the first
air carrier authorized by the FAA to
use the RNP procedures at Reagan
National. The airline pioneered the
use of RNP procedures at Juneau and
other airports in Alaska.

Besides the new procedure at Reagan
National, the FAA has authorized RNP
procedures at Juneau, San Francisco,
Portland, OR; Palm Springs, CA; and
Hailey (Sun Valley), ID.

At all the airports,
RNP's "repeatability" — allowing
aircraft to fly the same path
consistently — lets the FAA
design procedures to avoid noise-
sensitive areas with the assurance
that aircraft will fly the exact path
every time.

The FAA and the aviation community
have collaborated for more than a year
to make performance-based navigation a
reality. When performance-based
navigation is fully implemented at
airports across the nation, it will
establish precise approach, arrival
and departure procedures. It also will
improve situational awareness for
pilots and air traffic controllers,
and provide smoother traffic flows,
saving fuel and benefiting the
environment.
