GE Aviation is designing and deploying the first Required Navigation
Performance-Authorization Required (RNP-AR) to Instrument Landing System (ILS)
flight procedure in China for Air China Southwest. Merging the two
technologies will provide more efficient routing and improved access for
flight operations at Xi Chang airport.

“Using GE’s method of merging RNP to the ILS, operators can experience the
track mile reduction benefits of RNP with the lower decision altitudes a
precision landing system provides,” said Giovanni Spitale, general manager for
GE Aviation’s Air Traffic Optimization group. “Air China Southwest will have
continuous lateral and vertical guidance all the way to the runway while
navigating the challenging mountainous environment of Western China.”

The Xi Chang RNP to ILS procedure will save Air China Southwest up to 14
nautical miles per approach, compared to the conventional ILS procedure. GE
also designed an RNP AR approach to the non ILS-equipped runway, reducing the
decision height by more than 575 feet compared to the existing approach.
Because RNP paths rely on satellite-based navigation technology, the airline
does not have to rely on the outdated, ground-based navigation aids in place
at the airport, improving schedule reliability.

Current operational problems at Xi Chang include weather related delays,
one-direction traffic, flight cancellations, and tail wind limitations on the
ILS runway. The GE-designed procedures will improve all-weather operations and
allow for arrivals and departures on both runways. On departures, GE’s RNP
procedures provide engine-out protection throughout the most critical time to
the enroute structure. Xi Chang airport is located in Sichuan province,
southwest of Chengdu, in a five kilometer wide (16,400 feet) valley at 1,588
meters (5,112 feet) elevation.

Since 2004, GE Aviation has worked closely with Air China and the CAAC to
implement a network of RNP AR procedures in China. GE has deployed RNP paths
at seven other Chinese airports for the airline, improving access and schedule
reliability while reducing fuel and track miles to many of the mountainous
regions it serves.

In July, GE Aviation completed the world's first RNP AR to ILS with autoland
flight for LAN Airlines at Lima's Jorge Chavez International Airport. The
technology lowers the aircraft landing minima at Lima to 100 feet when the
three elements are combined. The utilization of the RNP AR transitions also
enables aircraft to fly east of the airport in airspace that was previously
unused due to terrain constraints.

PBN technology allows aircraft to fly precisely-defined flight paths without
relying on ground-based radio-navigation signals. RNP procedures, an advanced
form of PBN technology, can be designed to shorten the distance an aircraft
has to fly en-route, to reduce fuel burn and exhaust emissions and to reduce
noise pollution in communities near airports. Because of RNP’s precision and
reliability, the technology can help air traffic controllers reduce flight
delays and alleviate air traffic congestion.

GE Aviation’s Air Traffic Optimization Services group provides airlines, air
navigation service providers and airports with services to make the way we fly
more efficient. With Performance-based Navigation design and consulting,
high-resolution, digital airport maps, electronic terrain and obstacle data,
and airline-based flow management products, GE is building the foundation to
support air traffic modernization.
