1.7 The aircrew training process involves students being put through increasingly tailored training to operate different aircraft and systems, and undertake specific roles. As Figure 1 shows, it involves the Department selecting students (Phase 1); teaching them the basics of flying in training aircraft and simulators (Phase 2); and then providing operational training on front-line aircraft, such as Typhoon fast jets and Apache helicopters, within around 25 units across the front-line commands (Phase 3). Students then join operational squadrons.
