The operator certificates issued by the ULC (Civil Aviation Authority) from 2021 onwards remain valid for two years. This means that 2023 is the first year in which some of the certificates issued will expire. PANSA (Polish Air Navigation Services Agency) has recently posted a reminder on its website with instructions on how to update your certificate.
This should be done via the ULC website and the operator profile held there. Once you have verified your contact details and expressed your desire to renew your certificate. Then simply download and print the registration confirmation and take a screenshot of your operator profile. The final step is to update the certificate validity information on the PansaUTM website, use the screenshot you took earlier for this.
