The Avionics Systems Trainer (AST) developed by Airborne and Space Systems Division, provides a unique training platform for first line avionics systems maintenance mechanics and technicians. Users are provided with an environment that simulates the cognitive processes involved with operating or maintaining any military fast jet or rotary wing aircraft such as Typhoon, F-16, Apache, Tornado or Hawk. AST is designed to enable students to completely familiarise themselves with aircraft systems and associated maintenance procedures and test equipment, in a safe classroom environment under controlled conditions of instruction, timescales and course management.
