# Analysis of Drone Flight Stability for Building a Korean Urban Air Traffic (K-UAM) Delivery System
## 6 Summary and Discussions  
The Ministry of Land, Infrastructure, and Transport of South Korea established the 'K-drone delivery promotion team' to commercialize drone delivery services in urban areas and present a standard model, and announced the 'Drone Delivery Guidelines' to promote pilot projects targeting some local governments. It stipulates that drones used for delivery services must conduct flight tests to maintain flight paths and altitudes as part of safety measures to prevent damage caused by collisions with ground personnel or obstacles in urban areas, and that decisions on whether to deploy them for delivery work be made based on the test results. In this paper, we collected and analyzed the flight data of the drone body. The drone flight was measured along the delivery path and hovering, and an error analysis on the flight stability was performed to confirm whether it met the regulations. The relevant regulations are as follows:  
* Drone Flight Data Analysis--Route
* The drone maintains flight within a 10 m margin of error from the planned route line.
* The drone's flight altitude is also maintained within 3 to 10 m from the planned flight altitude.
* Drone Flight Data Analysis--Hovering
* The left and right radius error during drone takeoff and landing must be within 3 m.
* The altitude error for maintaining the hovering must be within 3 m.  
As a result of analyzing the drone flight path data conducted in Uliu and the hovering data conducted in Yeosu, there were moments when the distance within the regulation was temporarily exceeded, but the error rate of the entire section data satisfied the criterion of within 3%. Therefore, the drone's body stability evaluation analyzed in this paper is considered to have been passed. Based on the results of this study, the data are expected to serve as a cornerstone for establishing guidelines for drone delivery flight data analysis regulations.
