DJI Releases SAIL III OSO Declarations For Dock 3 And Matrice 4D

DJI has published a complete package of SAIL III OSO declarations for the DJI Dock 3 and Matrice 4D Series, giving operators manufacturer-backed evidence to support SORA applications in EASA member states. Announced on 14 July 2026, the package covers all eight design-related Operational Safety Objectives required at SAIL III. For teams planning automated BVLOS operations, this removes one of the biggest technical hurdles between a business case and an operational authorisation.

What DJI Has Announced

For enterprise drone teams, the hardest part of scaling operations has rarely been the aircraft. It has been airspace access, and the mountain of structured evidence a regulator expects before granting authorisation for operations beyond the standard scenarios.

DJI has now completed a SAIL III declaration of compliance package for the design-related Operational Safety Objectives that apply to the DJI Dock 3 and the Matrice 4D Series. In practical terms, DJI, acting as the UAS designer, has already carried out the testing, analysis, and design reviews behind each objective, and has issued signed declarations that operators can drop straight into their own SORA submissions.

Operators, dealers, system integrators, and platform providers can all reference the package when preparing SORA-based applications up to SAIL III in EASA member states.

What SAIL III Means In A SORA Application

SORA, the Specific Operations Risk Assessment, is published by EASA as an Acceptable Means of Compliance to Article 11 of Regulation (EU) 2019/947. It rolls ground risk and air risk into a single outcome called the Specific Assurance and Integrity Level, or SAIL, which runs from I to VI. Each level sets out the Operational Safety Objectives an operator must meet and how robust the evidence needs to be.

SAIL III sits in the medium-risk band of the specific category. It typically applies to operations beyond the reach of the standard scenarios, including automated dock-based BVLOS flights, drone-as-first-responder programmes over semi-populated areas, infrastructure and utility inspection across low to medium density areas, and perimeter security patrols with automated dispatch.

Why The Declarative Approach Matters

The key distinction at SAIL III is how design-related safety objectives are verified. At this level, the competent authority may accept declarations of compliance issued by the UAS designer, assessed against Means of Compliance published by EASA's Airworthiness Task Force. At SAIL IV, the bar rises sharply, and compliance must be demonstrated through an EASA-issued Design Verification Report.

That difference is significant. It means a Dock 3 or Matrice 4D operator does not need to reconstruct DJI's technical arguments from scratch or commission months of independent design analysis. They incorporate DJI's signed declarations into their compliance package alongside their Concept of Operations, risk assessment, and operational procedures.

What The OSO Package Covers

The package addresses the eight design-related objectives that apply at SAIL III:

• OSO 2, competent manufacturer and quality system
• OSO 3, maintenance and continued airworthiness support
• OSO 5, system safety and reliability
• OSO 6, C2 link performance and link-loss behaviour
• OSO 8, flight manual documentation and operational information
• OSO 18, flight envelope protection
• OSO 19/20, human factors and HMI
• OSO 24, environmental robustness and safe operating envelope

Taken together, the declarations give a regulator, a SORA consultant, or an internal safety team a structured, traceable view of the platform from the designer's perspective. The operator remains responsible for everything outside the designer's scope, including the ConOps, the ground and air risk assessment, operational procedures, and training.

What This Means For UK Operators

The declarations apply directly to SORA applications in EASA member states, but the direction of travel matters just as much on this side of the Channel. The CAA is rolling out its own UK SORA framework, which follows the same risk-based logic of ground risk, air risk, and assurance levels. Manufacturer-backed design evidence of this kind shows how the ecosystem is maturing, and it strengthens the case for dock-based BVLOS programmes that UK operators are building towards today.

FAQs

What is SORA in drone operations?

SORA stands for Specific Operations Risk Assessment, a methodology for assessing the risk of drone operations that fall outside the open category. It combines ground risk and air risk into a single classification that determines the safety objectives an operator must meet before receiving an operational authorisation.

What is a SAIL level in drone regulations?

SAIL stands for Specific Assurance and Integrity Level, and it runs from I to VI. The higher the SAIL, the more demanding the Operational Safety Objectives and the more robust the evidence required, with SAIL III sitting in the medium-risk band of the specific category.

What are Operational Safety Objectives?

Operational Safety Objectives, or OSOs, are the individual safety requirements a SORA assessment assigns to an operation, covering areas such as manufacturer competence, maintenance, link reliability, and human factors. Each OSO must be met at a level of robustness that matches the SAIL of the operation.

Does the UK use SORA for drone operations?

The UK CAA is introducing its own version of SORA for the specific category, adapted from the international JARUS methodology. UK operators applying for operational authorisations will increasingly follow this risk-based process, which mirrors the ground risk, air risk, and assurance structure used by EASA.

Final Thoughts

The SAIL III OSO declaration package for the Dock 3 and Matrice 4D Series does not hand anyone an authorisation, and it does not replace a well-constructed SORA submission. What it does is remove a substantial share of the technical burden at the design level, backed by the manufacturer itself. For operators building the case for automated BVLOS operations, the evidence base just became considerably stronger.
