As Europe's 1 January 2000 deadline for compulsory fitting of Airborne Collision Avoidance System II (ACAS II) approaches, AlliedSignal has received Federal Aviation Administration approval for its CAS81A and CAS 67A systems, designed for large transport and regional aircraft. These meet the Change 7 specification that reduces nuisance alerts, clarifies warnings and reduces transmission clutter. AlliedSignal is also offering software upgrades to traffic alert and collision avoidance systems to Change 7 level.
