Vigilance maintained at all times, or “See and avoid” concept recommended is a primary means of mid-air collision avoidance. It is well known to be difficult to detect aircraft mid-air on a collision course which has constant relative bearing to another aircraft and constant velocity of each aircraft. To understand the collision course making other aircraft appear motionless is essential for pilots to avoid mid-air collision. Since 2008, Aeromedical laboratory has conducted flight simulation of a collision course for cadets. This simulation flight consists of three sections, including the comparison of a collision course with a non-collision course, attention distribution, and visual scanning. Our collision course simulation effectively provides knowledge of visual scanning, attention distribution, see-and-avoid other aircraft, and human perceptual limitation.
