Hawker 750 and 900XP to Feature Aircell® Axxess II Capabilities September 24, 2007 ATLANTA, Ga. - Sept. 24, 2007 – Our new Hawker 900XP midsize and Hawker 750 light-midsize jets will enter service with the option to be equipped with Aircell’s AxxessTM II satellite communications system. The option was developed for the airplane through a supplemental type certificate (STC) by Hawker Beechcraft Corporation’s Designated Alteration Station at their Little Rock, Ark. facility. The system will have future upgrade capabilities to Aircell’s broadband wireless connection when that system becomes available sometime next year. “Adding Aircell’s Axxess II satellite communications system as an option to the Hawker 750 and Hawker 900XP equips these segment-leading aircraft with the communications technology our customers need to remain connected while in flight,” said Brad Hatt, president Commercial Sales. “This is the first STC by our new designated alteration station in Little Rock, and I anticipate we will see many more STC’s developed to provide the types of communications, entertainment and cabin amenities our customers require in their new Hawker aircraft.” Aircell Axxess is a family of latest-generation, multi-channel, satcom systems designed for medium-to-large business aircraft. With its “network neutral” design philosophy, Aircell Axxess equips aircraft with a modular, flexible cabin architecture that serves the operator’s needs today, and provides the ability to upgrade as new technologies and links – such as Aircell broadband – become available in the future. Aircell Axxess comes standard with two built-in channels of Iridium satellite communications for quality, worldwide voice services with full PBX functionality. Also standard are Aircell’s new, FAA-certified handsets with large, color displays – an industry first – as well as advanced noise reduction technology and standard ear bud/headset jacks for clear, quiet calling. Wireless capabilities include a full 802.11b/g Wi-Fi “hotspot” which, when paired with a broadband connection, such as Inmarsat or Aircell broadband (2008), can be used to operate personal laptops, PDA’s and other Wi-Fi devices in the cabin. Using integrated expansion ports, up to two additional Iridium channels can be added to Aircell Axxess to suit an operator’s needs. Additional system capabilities are added regularly.
