If you already have a good understanding of the Part 101 drone rules, but have realised what you want to do doesn't comply, you need a Part 102 unmanned aircraft operator certificate.
Part 102 Unmanned Aircraft Operator Certification outlines how to obtain an unmanned aircraft operator certificate. You need a certificate if you want to fly an unmanned aircraft outside of the Part 101 rules - such as operating unshielded at night, flight over property with prior notification, or with an aircraft that weighs more than 25 kg.
Part 102 is assessed on the risk of the operations you will be conducting. To operate with a variation from the Part 101 rules, you will need to show how you can manage the risks associated with that particular activity.
You will be required to provide us with an operating manual showing how you have identified the hazards and risks of your operation, and the ways you will mitigate those risks. Each application is considered on its merit.
Having determined that you need to be certificated for your type of operation, you need to fill out the application form and the Part 102 compliance matrix. Find these on Advisory circulars.
If your operations will involve new or emerging first of type aircraft or technologies; then you may also benefit from engaging with our Emerging Technologies Programme.
