Safety systems
for the shared sky.

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.

01
EASA compliant

Designed around MoC Light-UAS.2511-01 for SAIL III operations.

02
Independent architecture

Fully segregated from the UAS flight control system — no single point of failure.

FTS

An independent safety layer that terminates a drone's flight on demand — engineered for SAIL III operations and certified communication reliability.

Standard EASA MoC Light-UAS.2511-01
Range 5 to >100 km depending on model and application
Architecture Drone systems independent - Full Duplex operation
FTS-equipped drone in flight
01 Onboard installation
FTS ground controller unit
02 Ground controller

Built around four principles.

01

Independent operation

The FTS runs entirely outside the drone's flight control architecture. A failure in the UAS cannot propagate to the safety system.

02

Full-duplex link

Proprietary bidirectional communication with confirmation telemetry, operating reliably across 5 to >100 km depending on variant.

03

Power-level termination

Unlike many FTS solutions that use mechanical relays - which are prone to failure under the high-vibration and high-current environments of heavy drones - our system utilizes a digital termination bus-trigger, CAN BUS, PWM, etc.
This ensures a clean, 100% reliable motor-stop command every time.

04

Parametrization and fleet management

Bluetooth interface which allows parametrization of each unit and easy drone fleet management.
Activation options and communication parameters are configurable per platform and operational profile.

Two configurations.
One safety standard.
