A senior UK Civil Aviation Authority safety manager says that the UK proposal to the European Civil Aviation Conference to make airborne collision-avoidance systems (ACAS) compulsory will include aircraft with more than 30 seats or weighing more than 15t for an implementation date in 2000.
The manager says that the traffic-alert and collision-avoidance system (TCAS2) almost certainly recently saved a mid-air collision between two Boeing 747s operated by Cathay Pacific and Northwest Airlines over the Pacific.
