STS-01 vs STS-02: which do you need?

STS-01 overview

Typically covers VLOS operations in controlled ground areas with defined separation from uninvolved people.

STS-02 overview

Addresses flights near people with additional mitigations — common for event and inspection work within limits.

How to choose

• Match the STS to your actual operation — do not pick by exam convenience
• Both require STS theoretical knowledge and operational declaration
• Complex BVLOS still needs Specific category authorisation
