It is common practice of VFR that pilots report their position and subsequent attempts via radio. Simply speaking, VFR, a typical method of flight control uses radio communication to track dynamic position of aircraft. Due to the variety of terrains and induced coomunication obstacles, radio communication tends to create blind spots for the air traffic control. Mobile communication carriers commonly used in the ground taxi system provide real-time postioning function. This study proposes the idea of implementing a mobile communication carrier in a flying helicopter. This research then investiges the effective ranges of the existing wireless communication systems affected by different locations, angle of antenna, and congestion status. The investigation results would justify if the mobile communication carriers can be reliably applied to the domestic VFR helicopter to achieve self-positioning and track monitoring, and therefore to enhance aviation safety and air traffic control. The commercial vehicle tracking system provided by Chunghwa Telecom Co. is used in this study. The main testing items include the real-time positions and heights of the testing helicopter, the effective signal delivery rate, the real-time monitoring display screen appearance in the monitoring end. During the testing periods, the positioning signals are transmitted every 30 seconds. The testing runs in this study showed that antenna angle, location, height, and servicing popularity of a base station would affect the monitoring display screen appearance performance in the monitoring end. The investigation results concluded that a ground based mobile communication carrier is able to provide helicopter pilots and the monitoring end accurate real-time positioning informations.
