L-3's SafeRoute(TM) Set to Certify.

-- L-3 Submits TSO Paperwork for First ADS-B Product for Commercial Aviation --

-- Provides Cockpit Solution for Runway Incursions & Approach Sequencing --

LE BOURGET, France -- L-3 Communications (NYSE: LLL) announced today that Aviation Communications and Surveillance Systems (ACSS), an L-3 Communications & Thales Company, has met all of its development milestones on schedule, since SafeRoute[TM] development was announced at the 2005 Paris Air Show, leading to the submittal of technical standard order (TSO) documentation to the Federal Aviation Administration (FAA) last Friday, June 15.

With TSO paperwork submitted, L-3 now looks forward to receiving certification in the coming weeks for the first automatic dependent surveillance-broadcast (ADS-B) product for commercial aviation. UPS will begin fleetwide installation of SafeRoute beginning this summer.

"This is truly an historic event," said Kris Ganase, President of ACSS, who, at the Paris Air Show in 2005, announced the SafeRoute development program and UPS Airlines as the launch customer. "There are not many avionics suppliers who say they will certify in a certain time frame and actually do it. It's a credit to our great team at ACSS, a motivated launch customer in UPS, and a group of innovative partners who helped us bring this product to market on time."

L-3 acknowledges the following partner companies for their contributions to the program:

* Astronautics - Joint developer with L-3 of the Cockpit Display of Traffic Information (CDTI) software

* Boeing - Supplier of the Electronic Flight Bag (used to display SafeRoute in the cockpit for UPS)

* Gables Engineering - Developer of the ADS-B Guidance Display (AGD) which interacts with the L-3 Surveillance Processor to display SafeRoute information

* Jeppesen - Provider of navigation and airport map database

"The FAA also deserves thanks for working closely with us to bring the anticipated timeline for developing and implementing this technology forward," said Mr. Ganase.

SafeRoute is a unique set of safety and efficiency software solutions based on ADS-B technology. The system features two unique functional areas: Surface Area Movement Management (SAMM) and Merging & Spacing (M&S).

The SAMM application provides flight crews with an airport surface map and tracks the movements of aircraft and other ground and airborne traffic in the terminal area, and alerts crews of potential conflicts. With more and more attention being paid to the issue of runway incursion, business jet OEMs and operators are looking for solutions to what the FAA has called its "number one safety concern." The SAMM application within SafeRoute delivers enhanced situational awareness by using aircraft onboard surveillance technology coupled with squittered ADS-B information to display traffic on an airport map to reduce the possibility of runway incursions.

The SafeRoute M&S function makes use of on-board aircraft surveillance capability to provide flight deck spacing commands that allow aircraft to follow one another at the safest, most efficient interval possible from cruise altitude to the runway. M&S will ensure more consistent aircraft spacing while increasing capacity within the terminal airspace. M&S will also enable Continuous Descent Arrivals (CDA), which will further increase efficiency.

"Successful trials with CDAs flown in 2004 show the potential to achieve a 30 percent reduction in noise and a 34 percent reduction in emissions," said Capt. Karen Lee, UPS Director of Flight Operations. "We also expect significant fuel savings from keeping our planes at higher altitudes longer and being able to get our planes on the ground faster."
