Aviation Warning Systems designs and manufactures certified safety and communication systems for unmanned aerial systems — from independent flight termination to long-range telemetry.
As drones operate closer to populated areas and shared airspace, regulatory bodies demand stricter safety guarantees. Our systems are engineered to meet and exceed EASA requirements up to SAIL III, giving manufacturers and operators a reliable path to compliance.
Designed around MoC Light-UAS.2511-01 for SAIL III operations.
Fully segregated from the UAS flight control system — no single point of failure.
Embedded and retrofit variants, customizable to your platform and operation.
An independent safety layer that terminates a drone's flight on demand — engineered for SAIL III operations and certified communication reliability.
The FTS runs entirely outside the drone's flight control architecture. A failure in the UAS cannot propagate to the safety system.
Proprietary bidirectional communication with confirmation telemetry, operating reliably across 10 to 50 km depending on variant.
High-power relay disconnects the drone's battery supply directly — up to 60A on the Retrofit model.
Range, activation options and communication parameters are configurable per platform and operational profile.
For high-power drones like DJI Agras series. Direct integration with existing power systems, capable of disconnecting loads up to 60A.
Designed to be integrated by drone manufacturers. Standard TTL, UART and I²C connectivity for flight controllers.
High-power variant for extended-range operations. Doubles transmit power and adds receiver sensitivity for long-haul missions.
