Simulations have been a fixture of aviation training for many years. Advances in simulator technology now enable modern flight simulation to mimic very closely the look and feel of real world flight operations. In spite of this, responsible researchers, trainers, and simulation developers should look beyond mere simulator fidelity to produce meaningful training outcomes. Optimal simulation training development can unquestionably benefit from knowledge and understanding of past, present, and future research in this topic area. Due to decades of research dedicated to simulation training in aviation, this may be easier said than done. As a result, this volume of key writings will prove invaluable as a reference, to help guide exploration of critical research in the field. By providing a mix of classic articles that stand the test of time, and recent writings that illuminate current issues, this volume informs a broad range of topics relevant to simulation training in aviation.
