隨著無人飛機在民用的領域上蓬勃發展，無人飛機與載人飛機共用空域的安全議題在西方國家已經討論了十年左右。因此，建立無人飛機之法規已是刻不容緩。除了將操作限制及應具有之配備列入考慮，同時也要劃分出合理的空域供無人飛機使用。
目前台灣空域的使用以載人飛機為主，本論文在劃分無人飛機可使用空域置重點於飛航安全。因此，使用的參數包含了平均無故障時間、地形條件、管制空域及限制空域。由於空域的擁擠，有效率的使用空域將會讓空中交通更為順暢，因此本論文也特別對空域容量進行分析。

The sharing of airspace by both manned aircraft and unmanned air vehicles (UAVs) has been an issue for decades. In recent years the fast growth of civil UAV activities has led to the concern for their threat to aviation safety. Hence, it is becoming more important to establish regulations for UAV operation. The aviation regulations must prescribe not only the required performance and equipment of UAVs, but also the allowable airspace for UAV activities.
Regarding the airspace monopolized by manned aircraft in Taiwan, this thesis is intended to focus on the study of the allowable airspace demarcated by safety issues. For this reason, parameters involved will cover Mean Time Between Failures (MTBF), terrain controlled airspace and restricted airspace. Analyzing the capacity in limited airspace is also included from efficiency and effectiveness aspects.
