Rainmaker Technology’s initiative to deploy cloud-seeding flares using small drones is under scrutiny after the Air Line Pilots Association (ALPA) urged the Federal Aviation Administration (FAA) to reject the startup’s request unless it complies with stricter safety guidelines. The FAA’s decision on this matter will be pivotal for the future of weather modification via unmanned aerial systems. Rainmaker’s proposal involves using two types of flares on its Elijah quadcopter to stimulate precipitation, operating within controlled airspace, which requires Air Traffic Control’s permission. ALPA raised concerns about safety risks, foreign object debris, and the environmental impact of chemical agents, emphasizing the lack of trajectory modeling and environmental analysis in the petition. Rainmaker has assured operations will occur over rural areas on private properties, aiming to enhance the safety and effectiveness of cloud-seeding practices traditionally executed by crewed airplanes.
