Weather can change a drone mission before launch or while the aircraft is already in the air. This section explains how wind, gusts, visibility, precipitation, temperature, clouds, pressure, and local conditions relate to flight planning, aircraft performance, battery behavior, sensor results, and operational limits, so forecasts can be turned into better go or no-go decisions.

Meta-learning MPC improves quadrotor tracking in controlled strong-wind flight tests
Researchers tested a meta-learning augmented model-predictive controller that estimates residual aerodynamic force online and feeds it back into the MPC model. In their fan-array experiments, with nominal wind settings up to 16 m/s measured 1 m downstream of the fans, the method improved average tracking performance by 50.6% over a GP-MPC baseline in real flight and 73.5% in simulation; the maximum reported reductions were 59.7% and 86.5%, respectively.

SP Electricity North West, Skyports Drone Services and eSmart Systems announced Project VOLT, a trial of remotely piloted docked drones for rapid fault finding and asset-condition monitoring on the electricity network in the Lake District. Captured imagery is intended to feed eSmart Systems' AI-based inspection workflow.

Dynamic soaring turns wind shear into speed, but the load case is unforgiving
A radio-controlled sailplane can exceed the speed of the wind that powers it, without a motor or propeller. The trick is to fly repeatedly between air masses moving at different speeds and to turn at the right points in the cycle. That deceptively short explanation leaves out the engineering problem: as the glider accelerates, the same turn radius demands much larger control forces, structural loads and aerodynamic margins.

The University of Alaska Fairbanks now has a useful piece of infrastructure for a problem that small-drone engineering often treats too casually. Its Supercooled Water Experimental Arctic Tower, or SWEAT, can create calibrated icing conditions around a flying multirotor inside a roughly 16-foot vertical test space.
