Innovative Approaches to Fog Dispersal: The Emerging Role of Unmanned Aerial Vehicles

The present study explores the application of UAVs as deliverers of fog dispersal chemicals to increase airport visibility. Methods with traditional fog dispersal techniques that involve thermal heating and hygroscopic seeding from ground-based systems are also constrained in both price and efficacy. The approach consists of arming UAVs with systems aero-dropping seed-like hygroscopic particles or spraying into fog. Analysis has shown that a UAV with a 1000 kg payload could perform a 30-minute seeding mission over a 2 km<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> airport area at seeding rates known to increase visibility. UAVs bring, among others, targeted delivery, the ability to operate autonomously, flexibility in flight paths, and lower operation costs compared to manned aircraft. The findings suggest that the DAV s could offer a more efficient and cost-effective means to combat widespread fog around airports. Nevertheless, more research still needs to be done concerning in-field tests and operational implementation to develop UAV seeding strategies and assess fog clearing by UAVs. That strategy can relieve air traffic congestion and improve aviation safety in foggy events.
