GM1 Article 11GM1 Article 11Version 1Effective -Verified 21 August 2026

In plain language

If your flight plan goes outside the boundaries of a PDRA, you cannot use that PDRA. You must perform a full risk assessment, unless your authority explicitly approves minor changes.

Requirement as structured

EASA advises that if a UAS operation does not fit completely within the limits of a PDRA, the operator must conduct a full risk assessment, unless the competent authority accepts minor changes.

Original regulatory text

If the UAS operation does not fit completely within the limits of the PDRA, the UAS operator is required to conduct a full risk assessment and submit it to the competent authority. Changes to the PDRA should not be done, unless the competent authority accepts that minor changes should be made.
