What is the difference between PDRA01 and UK SORA?

PDRA01 and UK SORA are two main pathways in the UK Specific Category.

PDRA01 is a predefined risk assessment used for standard drone operations that meet specific limits, such as VLOS flights and minimum distances from people.

UK SORA is a custom risk assessment framework used for more complex or higher-risk operations that fall outside PDRA01 conditions.
