CAA’s Letter to PDRA01 & OSC Holders on SORA Transition

See below the letter sent on 7 February 2025 to all PDRA01 holders on SORA Transition. OSC holders received a very similar letter. In short:

PDRA-01 OAs are not affected by the introduction of UK SORA. No expected changes before 31 March 2026.

Introduction of UK Specific Operation Risk Assessment (UK SORA)

  • UK SORA will replace the OSC methodology (CAP 722A) in Q2 2025.
  • Aims to provide more transparent, structured, and consistent risk assessments for UAS operators.
  • Based on JARUS SORA v2.5.
  • A new digital UK SORA Application Service will streamline applications.

Differences Between UK SORA and OSC-Based Applications

  • UK SORA is quantitative, reducing subjectivity in risk assessments.
  • The application is online and guides users through SORA steps.
  • The process is split into two phases, so all assurance evidence is not required at the start.
  • An online calculator will help applicants determine necessary mitigation measures.

Impact on Current Operational Authorisations (OAs)

  • Existing OSC-based OAs remain valid until expiry.
  • Renewal using OSC is possible only before the UK SORA Application Service goes live.
  • New applications after UK SORA implementation must use the UK SORA process.
  • Two webinars will be set up directly by the CAA to guide operators.

Key Dates

  • Q1 2025 – UK SORA policy published (not yet in force).
  • Q1 2025 – Remote Pilot Competency Policy published.
  • Q2 2025 – RAE(F) and SAIL Mark policy concepts published.
  • Q2 2025 – UK SORA goes live and becomes mandatory.
