NOTE:-CAP722H is still undergoing significant changes at the CAA. This article will be updated to reflect that
The use of unmanned aircraft systems (UAS) or drones has been increasing rapidly over the last few years. As with any new technology, there are concerns about safety and regulation. To address these concerns, the Civil Aviation Authority (CAA) of the United Kingdom has published CAP722H Edition 1, a comprehensive guide to UAS operations in the UK. This article will provide an in-depth understanding of CAP722H Edition 1 and its various aspects.
Overview of CAP722H Edition 1
CAP722H Edition 1 is a 111-page document that aims to provide guidance to UAS operators, including hobbyists, professional operators, and public organizations. The document is divided into six chapters, each of which focuses on a specific aspect of UAS operations.
Chapter 1: Introduction and General Principles
The first chapter of CAP722H Edition 1 provides an overview of UAS operations and introduces the general principles that underpin the guidance provided in the document. The chapter emphasizes the importance of safety, and the need to ensure that UAS operations are conducted in a responsible and safe manner.
Chapter 2: Legal and Safety Requirements
The second chapter of CAP722H Edition 1 covers the legal and safety requirements that operators must meet before engaging in UAS operations. This chapter discusses the responsibilities of operators, and the CAA's enforcement powers. It also covers the requirements for obtaining a operational authorisation which is necessary for PDRA 01 UAS operations.
Chapter 3: Airspace and Operating Environment
Chapter 3 of CAP722H Edition 1 delves into airspace and operating environment considerations. This chapter covers topics such as UAS altitude restrictions, airspace classifications, and the use of air traffic control services. It also discusses the factors that operators should consider when selecting a location for UAS operations.
Chapter 4: Operations and Procedures
Chapter 4 of CAP722H Edition 1 discusses UAS operations and procedures. The chapter covers topics such as pre-flight checks, emergency procedures, and the use of UAS in congested areas. It provides a framework for operators to identify and mitigate risks associated with UAS operations.
Chapter 5: Technical and Performance Specifications
Chapter 5 of CAP722H Edition 1 provides technical and performance specifications for UAS. This chapter covers topics such as UAS weight and size limitations, UAS noise and emissions, and UAS system redundancy. It also discusses the requirements for UAS equipment, such as cameras and sensors.
Chapter 6: Appendices
The final chapter of CAP722H Edition 1 contains appendices that provide additional information on UAS operations and procedures. The appendices cover a range of topics, including UAS maintenance, record-keeping, and insurance requirements.
Key Features of CAP722H Edition 1
CAP722H Edition 1 will provide a comprehensive guide to UAS operations in the UK. It covers all aspects of UAS operations, from legal and safety requirements to technical and performance specifications. Some of its key features include:
1. Safety-focus The guidance provided in CAP722H Edition 1 is designed to ensure the safe operation of UAS in the UK. It provides operators with a framework for identifying and mitigating risks associated with UAS operations.
2. Comprehensive: CAP722H Edition 1 covers all aspects of UAS operations, including legal and safety requirements, airspace and operating environment considerations, and technical and performance specifications.
3. User-friendly: Despite its comprehensive nature, CAP722H Edition 1 is written in a user-friendly manner. It is easy to navigate and understand, even for those who are new to UAS operations.

CAP722 is an essential guide for anyone who wishes to engage in UAS operations in the UK. It provides comprehensive guidance on all aspects of UAS operations, from legal and safety requirements to technical and performance specifications. CAP722H Edition is still going through siginificant 'tweaks' at the CAA so please do check back as this article will be updated to reflect that.
