Rainmaker Technology\u2019s bid to deploy cloud-seeding flares on small drones is running into turbulence. The Air Line Pilots Association (ALPA) has urged the Federal Aviation Administration (FAA) to deny the startup\u2019s request unless stricter safety conditions are met.<\/p>\n\n\n\n
The FAA\u2019s upcoming decision could set a precedent for how the regulator handles weather modification projects using unmanned aerial systems. For Rainmaker, the ruling could determine whether its drone-based approach takes flight.<\/p>\n\n\n\n
ALPA told the FAA that Rainmaker\u2019s petition \u201cfails to demonstrate an equivalent level of safety\u201d and poses \u201can extreme safety risk.\u201d The union highlighted unclear details about flight altitudes, airspace, and the use of flares, raising concerns over potential debris, fire hazards, and environmental impacts.<\/p>\n\n\n\n
The union also noted that Rainmaker\u2019s Elijah quadcopter, which carries the flares, has a maximum altitude of 15,000 feet MSL \u2014 inside controlled airspace used by commercial jets. Without precise flight data, ALPA says the plan risks collisions.<\/p>\n\n\n\n
Rainmaker CEO Augustus Doricko countered that the objections were based only on the public notice, not the non-public documents submitted to the FAA that include risk mitigations. He said operations would be restricted to predetermined safe airspace with coordination from aviation authorities.<\/p>\n\n\n\n
\u201cIndependent bodies like the EPA and multiple state agencies have studied cloud-seeding materials for over 70 years and never found any adverse effect,\u201d Doricko said, dismissing ALPA\u2019s environmental concerns.<\/p>\n\n\n\n
Sam Kim, Rainmaker\u2019s aviation regulatory manager, added that the use of flares is for research only, in controlled environments, and will eventually be replaced by the company\u2019s proprietary aerosol system.<\/p>\n\n\n\n
Cloud-seeding is not new. Since the 1950s, silver iodide has been sprayed into clouds to stimulate precipitation. Today, state agencies, water districts, and ski resorts commission crewed flights for this purpose.<\/p>\n\n\n\n
Rainmaker\u2019s approach swaps piloted planes for drones, aiming to reduce risks to human pilots while expanding precision and scalability. The company says a typical operation disperses 50\u2013100 grams of silver iodide \u2014 far less than the emissions released in a single hour of commercial flight.<\/p>\n\n\n\n
Flights would take place over rural areas and private lands where Rainmaker has agreements with property owners, the company said. Operations would also include certified pilots, collision-avoidance systems, and coordination with local air traffic control.<\/p>\n\n\n\n
The FAA has not yet ruled on Rainmaker\u2019s petition, filed in July. Instead, it issued a follow-up request for more details on operations and safety. The decision will shape how regulators treat novel weather-modification efforts that use drones instead of planes.<\/p>\n\n\n\n
If approved, Rainmaker\u2019s plan could shift the decades-old practice of cloud-seeding into a new era of unmanned systems. If rejected, the company may be forced to refine its technology or safety approach before moving forward.<\/p>\n\n\n\n
Either way, the FAA\u2019s ruling will mark a defining moment in the future of drone-assisted weather modification.<\/p>","protected":false},"excerpt":{"rendered":"
