Aviation directory Other users likely to utilize flight simulators are Aviation instructors. Simulators can give instructors great ideas for use in their ground classes and bring up important information instructors can use in pre-flight and post-flight instruction. Other instructors recognize the value of having virtual experiences to underscore and emphasize the classroom instruction, and they will use flight simulators within their classrooms. The advantage to flight simulators over "real" flying is that simulators can be programmed to adjust to the needs of individual pilots and learners. This holds true for both PC based simulators as well as the larger, commercial simulators that feature life size, full resolution instruments, cockpit enclosures, and often have large screen displays. Aviation directory allow the "pilot" to choose between a variety of equipment options, such as single engine, twin engine, or simple and complex aircraft. Full trainers, such as those used in the military, have 360-degree virtual environments, high-resolution screens and realistic controls, as well as lifelike training scenarios. While some of the information in the popularly available flight simulation programs is about 18 months out of date, for most pilots and learners, that isn't an insurmountable problem. For those who find it is an issue, third party companies provide updated Aviation charts constantly. Legitimate academic studies have shown that flight simulators do in fact improve pilot performance related to landing skills and instrument and flight control abilities. In addition, virtual training does enhance user performance in real life. So flight simulators are not only entertaining, but can be extremely useful to pilots in training, those interested in trying out being a pilot, and established pilots wanting to enhance their skills.
