Drone Pilot Certification
To fly a drone that weighs more than 0.55lb, you must register it with the FAA. The FAA requires that the drone broadcast a Remote ID. You must include that when registering your drone, unless you register it as recreational.
To get approvals for non-standard flights, you must be a registered pilot. To register as a pilot, you must pass Test 107.
