TRANSITION FROM OSC TO SORA
 
REGULATORY SORA COMPLIANCE FOR DRONE OPERATORS

We make your regulatory compliance simpler and faster — so you can focus on growth.

Transitioning from OSC to UK SORA is not a simple update, the safety methodology is different.​ The safety methodology is fundamentally different — and understanding that difference is critical.

TRANSITION FROM AN OSC TO A SORA OPERATIONAL AUTHORISATION

How different is SORA? 

  • Around 70% of OSC Operational Authorisations in the UK were based on reduced distances from uninvolved people. This concept does not exist under SORA. SORA quantifies ground risk probabilistically and implicitly accepts overflight.

  • OSC reduced risk to ALARP (as low as reasonably practicable). SORA requires a defined set of mitigations that bring operations to a specific Target Level of Safety — a different standard, requiring a different evidence structure.

Our core expertise

  • Transform reduced distance type OSC OA to SORA-based OA

  • BVLOS with Visual Mitigation

  • BVLOS in Atypical Air Environment

  • Test & Evaluation activities

  • Urban/dense environment

  • Containment issues

Qualification and framing of SORA application - Framing the Authorisation

  • Assessment of Ground Risk Class, Air Risk Class and SAIL level of intended operations.

  • Assessment of Containment requirements

  • Assessment of key gaps, including in terms of access to UAS documentation or functionalities

SORA Application preparation & submission to the Civil Aviation Authority

  • Documentation of each component of SORA and of each claim as the application progresses on the CAA application webportal

  • Support engagement with the regulator’s team

  • Prepare responses to CAA findings in an iterative improvement of claim documentation and safety argument

  • Document each OSOs Operational Safety Objectives applicable to the SAIL level

Operations Manual amendment

  • Amend the Operations Manual to incorporate the SORA risk assessment methodology as well as the documentation supporting each claim or safety argument in accordance with SORA
