Aerospace Instrument-Making Annotation << Back Decision-Making System for Departure of an Unmanned Aerial Vehicle Considering Various Technical and Climatic Factors Stepanchikov О.V., Fetisov V.S. This study examines the impact of meteorological conditions on UAV flights and proposes a method for considering UAV technical characteristics when assessing the feasibility of a flight mission under specific weather conditions. The influence of temperature and battery wear on the capacity of onboard batteries used as the UAV's power source is taken into account when calculating the maximum possible flight duration. An automated decision support system which analyzes the aircraft's technical parameters, payload weight, meteorological conditions, and provides either permission or prohibition for the flight is proposed. Keywords: Unmanned Aerial Vehicle, meteorological conditions, decision-making for departure, UAV flight planning. DOI: 10.25791/aviakosmos.5.2025.1483 Pp. 45-52.
