Previously, the F-15E Weapons Block of the Aircraft Systems Apprentice (F-15) Mission Ready Technician course was taught in eight hours to students slated for F-15E bases. The delivery method used for F-15E Safe for Maintenance (SFM) task training was lecture and student handouts only. In accordance with Standard Instructional System Design, a hardware-training device is needed due to the hands on nature and safety aspects of this task. In the early 1990s, the Armaments Apprentice School programmed funding for a hardware trainer but the device was rejected due to a cost of approximately $4M. By this time, negative feedback from the using commands on F-15E weapons training was growing. The Schoolhouse spent $425,000 to develop a "virtual" F-15E aircraft equipped with both cockpit and aircraft wing weapon pylons to fill the need for hardware-like skills training. The new Virtual Reality Interactive Courseware (VR-ICW) was devised to increase training quality, and decrease cost by using the "reference" F-15C/D SFM task performed on the real aircraft coupled with the "virtual" F-15E SFM task to provide a seamless learning experience. In general, students of the F-15E VR-ICW course, based on 1^st generation VR hardware, were pleased with course content and thought the course was well organized and easy to follow. However, a few students experienced varying forms of headache and nausea during their interaction in the virtual world. About 9% of the target population did not complete the course due to VR Sickness. The pointing device drew mixed reviews. Many responded they had trouble selecting some of the switches due to their location and very small targeting areas. Surveys indicated the majority of graduates believed VR-ICW positively impacted their job performance and the supervisors spent under four hours on aircraft training time. This is a saving of 22 hours, based on the provided estimate of 26 hours per student to reach the "go" proficiency level. Recommend augmenting other aircraft maintenance courses with VR-ICW technology.
