The report describes a study conducted to evaluate Device 2B24, which simulates the UH-1 helicopter and an instrument flight environment, and to determine its suitability for cost-effectively accomplishing the instrument phase of Army rotary wing flight training and facilitating UH-1 helicopter transition training, aviator proficiency evaluation, standardization, and flight training quality control. The three-phase mission suitability test involved examining the 2B24's advanced features in a training context, developing a new instrument training program for use with the device, and administering that training to 16 volunteer officers who had completed Army primary rotary wing training (100 hours) but had no helicopter or instrument flight experience. Results confirmed the device's mission suitability regarding both cost (per-student saving of over $4,000) and transfer of training (instrument training concluded in an average of 6.5 flight hours, as opposed to 60 flight hours for students in the existing program). Findings also indicated that the standardization, evaluation, and quality control goals had been partially met, and that the device's design is such that their fuller achievement is likely in the future. Four appendixes include: suitability test Army participants, course outline for UH-1 instrument and transition training, maneuver performance record forms, and reference material study guide. (Author)
