ARINC Brings Fuel Savings to Airlines with AirPlan enRoute(SM) Service.

ANNAPOLIS, Md. -- ARINC Incorporated and ATH Group of Lanham, MD today announced the AirPlan enRoute(SM) Service to bring much-needed fuel savings to commercial airlines. Based on the proven Attila(TM) arrival management system under an exclusive agreement with ATH, ARINC's AirPlan enRoute will be offered to selected airlines beginning this summer.

First implemented in 2006, the Attila system has saved fuel and reduced delays at one of the world's busiest airports by making adjustments in the arrival times of incoming flights. Fuel savings over $20,000 per day have been reported by a major U.S. carrier at this location. The Attila technology also yields more efficient use of available airspace and landing slots. Other benefits include reduced CO2 emissions, decreased noise pollution, and improved on-time performance.

ARINC's AirPlan enRoute will deliver the Attila functionality as a hosted service for multiple participating airlines at each airport served. AirPlan enRoute utilizes the airlines' existing ACARS([R]) communications technology, requiring no new avionics, no software modifications, and no changes to an airline's IT infrastructure.

"ARINC has a long history of integrating air traffic management innovations with air/ground data link technology," stated Robert Sapitowicz, ARINC Vice President, New Business Development. "The AirPlan enRoute service brings critical fuel savings at a time when airlines are dealing with ever-increasing fuel costs."

During typical operations, incoming flights to a busy airport tend to arrive unevenly and must be vectored onto long, time-consuming and costly approach patterns. The patented technology in the AirPlan enRoute system calculates improved arrival times--starting when aircraft are hours from landing--and sends recommended small changes to each aircraft's projected time at the arrival fix to achieve overall system goals and save fuel.

"Attila has shown significant results to date, leaving no question that arrival management can benefit airlines immediately with lower fuel usage and smoother operation," stated Michael Baiada, President, ATH Group. "By offering these benefits in a hosted service without upfront infrastructure costs, ARINC can accelerate the adoption of a much-needed advance in airline operational efficiency."

As a planning overlay that operates side by side with current ATC processes, AirPlan enRoute represents an evolutionary step in aircraft sequencing. The system considers all flights into an airport simultaneously, and also takes into account airline objectives such as operating schedule, gate availability, connecting flights, and crew legality when optimizing aircraft arrivals.

ATH Group, Inc. is backed by a development staff with more than 200 man-years of experience in air traffic control/management system development.
