Exhibit 1 Page 1 of 3 General Purpose and Description These radio station installations are required to accomplish FAA certification, system development and production check—out of an aircraft Terrestrial Flight Telephone System (TFTS). To support system development, DAC intends to activate the system in a laboratory environment in late ©96 (Sept — Oct) and follow with certification flight in mid ‘97 (June — Sept). Subsequent deliveries of this system will include system check out procedures which will activate the system. There are two radio stations involved, an aircraft station and a ground station. The aircraft station will be implemented in two configurations, one in a fixed based laboratory facility and subsequent mobile installations in the MD—90 aircraft. The ground station is needed to exercise the aircraft system and will be a portable test set or for more complex testing, a rack of test equipment. The ground station, although portable, will be used as a fixed based installation and will generally be located on the flight ramp or in a laboratory facility at Douglas Aircraft Company in Long Beach California. The system is in compliance with ARINC (Aeronautical Radio Incorporated) characteristic 752 "Terrestrial Flight Telephone System" and ETSI 300—326 (European Telecommunication Standard Institute) as developed for line—of—sight communications for commercial aircraft passenger telephone systems. Currently this system is operational in Europe and may grow to include other geographic areas such as Asia and the Middle East. Spectrum Planning Information Transmitter Frequency Band Air—to—Ground — 1800.0303 to 1804.9697 Ground—to—Air — 1670.0303 to 1674.9697 MHz Channel Spacing — 30.3 Khz RF Power Output Air—to—Ground — Transceiver output = +44 dBm. max EIRP = +44 dBm — 2 dB (Cable loss) + 3 dB (max ant gain) =+45 dBm (Mean) Ground—to—Air — Transceiver output = +40 dBm max EIRP = +40 dBm — 0.5dB (Cable loss) + 3 dB (max ant gain) = +43 dBm (Mean) Antenna The radiation pattern of both antennas will be omnidirectional and will be predominantly vertically polarized. Antenna Gain typically ranges from —15 dBi or less at certain azimuth and elevation angles to a maximum of 3 dBi Emission Type Emission Type Modulation Type Symbol Rate 44K2G7TZW 1/4 DQPSK 44.2 kbps Emission type is as defined in FCC rule making reports section 2.201. Site Data For the fixed based aircraft station configuration, the antenna is a 5 inch blade type antenna and will be installed on a flat aluminum ground plane. The antenna will be approximately 4 stories above the ground on the roof of Building 36 and will be less than 6 ft above the existing structure. The transmitter and associated equipment will be located adjacent (typically within 5 to 10 meters) to the antenna in an existing laboratory facility. The mobile aircraft installation (see Figure 1) will be operated within 350 Km of the ground station located at Douglas Aircraft Company in Long Beach California.

Exhibit 1 Page 2 of 3 The ground station is a portable test set or rack of test equipment depending on the extent of testing being performed and will be located typically on the roof of Bldg. 36 or on the flight ramp at Douglas Aircraft Company in Long Beach California. Table 1 below summarizes the four station configurations required and the planed activity for each.
