You'll need to know details of your proposed operations to calculate your SAIL and containment levels.
Remember, it's free to calculate your SAIL and containment levels
It's free to use the UK SORA-based Application Service to calculate your SAIL and containment levels.
This can be a good way to explore different options for your proposed operations.
You only pay if you submit your application.
You must have an Operator ID before you start.

Do I still need an operations manual?
You must have an operations manual.
You may use some sections of your operations manual as compliance evidence to UK SORA requirements. You should provide other compliance evidence, such as technical information, separately.
The application service helps you organise your evidence for submission to us.
