Risk Analysis

Understanding risk is essential when planning or operating your flight. Our Operational Analytics provide the basis for a risk determination on your flight, whether it’s just being planned or you're in the air right now.

Our approach to risk determination is based on the ASTM standard F3178-16, Standard Practice for Operational Risk Assessment of Small Unmanned Aircraft Systems (sUAS).

This standard is used to make risk assessments as part of the overall BVLOS approval process defined in ASTM standard F3196-18, Seeking Approval for Beyond Visual Line of Sight (BVLOS) Small Unmanned Aircraft System (sUAS) Operations.

Risk assessments are based on two factors: 

Severity of a particular condition and the likelihood of that condition occurring. While the severity of a particular condition is based on the specific flight CONOPS and is unique for each flight, the likelihood of the condition occurring can be assessed. 


At OneSky, we have developed an algorithm that uses the results from our Operational Analytics and determines the operational risk likelihood for each metric.  Combining these analytics, risk assessments and your specific flight logistics and CONOPs, complete the BVLOS picture needed for approval.  Use OneSky’s risk analysis service to know your risks, based on your criteria and the environment you’re flying in.

Leveraging existing global risk evaluation frameworks, we are developing a risk assessment tool that can be applied to your specific drone operations - including air and ground risk, population density, CNS availability, and more. We provide you with a high-fidelity understanding of risk throughout the entire flight profile, a critical component to obtaining certification or waiver approvals. 


In this video, we show how stakeholders can easily understand risk likelihood for a BVLOS operation, through three core metrics: communications signal strength, signal to noise ratio and GPS / GNSS precision error.

As with our Operational Analytics, flight planning is only part of the picture.  When the flight is in the air and something deviates from plan, you need to assess your risk for varying alternatives.  Our risk algorithm works in real time, right along with our operational analytics, to provide you with risk values that you can use to make a safe decision.
