Rockwell Collins has delivered its first TCAS 4000 Traffic Alert Collision Avoidance System to an 'unnamed' customer. Collins says that the system offers improved situational awareness to aircraft, providing surveillance capabilities of more than 100 nautical miles and significantly reducing system size, weight and cost.\rAlready, 300 orders have been placed for business and charter aircraft as well as regional airlines which are selecting the system to meet surveillance requirements. The system is fully compliant with the ICAO ACAS now required in Europe. Additionally, Rockwell Collins and Bombardier have recently completed preliminary design reviews with panel definition and preliminary display formats. Continental flight tests are scheduled for mid-2001 with aircraft certification and first deliveries to take place before the end of 2002.\rThe avionics suite includes TCAS II and EGPWS as standard and options such as turbulence detection and three dimensional FMS navigation map presentation. The suite also features Collins Engine Indication and Crew Alerting System (EICAS) which monitors, analyses and displays the performance of the aircraft engines. \rPro Line 21 avionics suites are also onboard Cessna Citation CJ1 and CJ2 aircraft which are currently undergoing certification flight tests. The first Pro Line equipped Cessnas will be delivered to customers next year. The Cessna suite will include solid state weather radar, dual channel automatic flight control systems, the Collins ADS-3000 air data sensor and the AHC-3000 attitude heading computer.\rCollins Pro Line 4 is now the standard avionics package for the Galaxy business jet.
