| Popis: | 96 Ultra light flight has been officially approved to use certification-free air vehicle into the flying market. However, how to provide low altitude flights with better safety performance, collision avoidance system must be taken into serious consideration. In the developing project on electronic flight instrument system (EFIS), GPRS is chosen to carry data communication to downlink GPS data to ground surveillance server. The collect aircraft data are then broadcast and uplink to the flying aircrafts for awareness of other aircrafts. According to CAA published legal airspace, this thesis tries to reconstruct and plan the airspace territory into terrain obstacle altitude marks in airspace boundaries into database. GPWS software adopts linear programming to formulate linear equation and ellipse equation to represent boundary or terrain. By real time constraint comparison from aircraft extrapolation line, any interpolations can be regarded as conflicts to the aircraft. Alert can then be generated to the pilot and the ground ATC. This function easily accomplishes the collision avoidance capability for ultra light operation in low altitude. |
