What are Operational Safety Objectives (OSOs)?
OSOs are the specific safety performance requirements that an operator must satisfy once a SAIL level is determined.
UK Regulation (EU) 2019/947 defines a series of OSOs covering areas including operator competency, UAS design and maintenance, crew training, operational procedures, and environmental conditions.
Each OSO is assigned a required robustness level - Low, Medium, or High - based on the operation's SAIL level.
