Digital avionics simulation for trainers

Faithful simulation of digital avionics in trainers requires realistic system performance over the full range of tactical operations that the students are expected to learn. The author describes how these requirements have been achieved in a ground-based helicopter tactics trainer. These requirements have been achieved for the 14H9 Tactical Team Trainer (TTT) developed for the US Navy SH-60F antisubmarine warfare (ASW) helicopter. This was done through the use of specially developed avionic simulation hardware and software. The high level of completeness and fidelity of simulation is a key ingredient in the ability of the TTT to accurately portray the SH-6OF helicopter tactical avionic system performance in a variety of conditions. Two student stations can be linked together to simulate realistic ASW team tactics operational scenarios. Each student station can also operate independently. The instructor, through the use of high-resolution color graphic display monitors and a graphical user interface, can efficiently control and monitor the training exercise
