Service Allows Operators To Integreate Real-Time GPS-Based
Navigation
A new service which allows operators to switch from using
traditional ground-based waypoint routes and procedures to
implementing real-time GPS-based required navigation performance
(RNP) operations has been introduced by Jeppesen, which developed
the service in coordination with technical support partner DW
International.
The "Jeppesen FlitePlan RNP Predictor" tool for commercial
aviation, business and private aircraft operators uses RNP
procedures to allows airlines to operate more efficiently by flying
more precise approaches based on satellite data, which reduces
overall fuel consumption and emissions output and mitigates
aircraft noise impacts. The new RNP solution improves upon
Jeppesen's pioneering receiver autonomous integrity monitoring
(RAIM) prediction technology, which provides predictions of GPS
satellite availability and assesses the integrity and accuracy of
GPS-based navigation signals.
Southwest Airlines recently became the first Jeppesen commercial
aviation customer to integrate the new RNP prediction
tool.
"The Jeppesen FlitePlan RNP Predictor is a new tool that enables
us to capitalize on our significant investment in RNP approaches
that will produce bottom-line improvement within Southwest
Airlines' operations," said Captain Jeff Martin, Southwest Airlines
assistant director of Operations. "Efficiency is the
foundation of our environmental commitment, and making the switch
from ground-to-satellite-based procedures will help us save fuel
and reduce emissions."
The Jeppesen FlitePlan RNP Predictor computes a prediction
report of the aircraft's Actual Navigation Performance (ANP),
considering factors such as aircraft type and configuration at a
particular time and place, given current GPS satellite status
information. The new RNP tool also enables both regional and
international operators to comply with all FAA, European, ICAO and
other global RAIM prediction requirements, implemented either as a
stand-alone service or integrated seamlessly with commercial flight
planning systems.
"We introduce our new Jeppesen FlitePlan RNP Predictor at a time
when the commercial aviation industry is seeking new ways to
operate more efficiently and institute cost savings," said Thomas
Wede, Jeppesen senior vice president and general manager,
Aviation. "Through reduced fuel burn, flying RNP procedures
will also allow airlines to operate in a more
environmentally-friendly manner. We are excited to offer this
new RNP prediction service that assists commercial operators in
improving performance."
By using the Jeppesen FlitePlan RNP Predictor, pilots accessing
GPS satellites for navigation, rather than ground-based radio
signals, will make more precise approaches to runways and will
spend less time waiting for clearances at increasingly congested
airports.
