Flight tests of Phoenix-based ACSS's T2CAS, a combined traffic collision avoidance system (TCAS) and terrain awareness warning system (TAWS), have begun on the company's modified Beech King Air C90.

The system has been chosen by Aeromexico, FedEx Express, Northwest Airlines and Virgin Express, as well as the US Customs Service for installation on its Lockheed Martin P-3 fleet. Although flight tests had been expected to start in July, ACSS maintains the system will be certificated by the end of the year and says initial TAWS functions have already been checked out.

ACSS, an L-3 Communications and Thales joint venture, is developing the T2CAS for new-build and retrofit applications, and expects to capitalise on its leading market position in existing TCAS equipment.
