Is the Part 107 course updated?

The Part 107 Exam Prep Course is regularly updated when the FAA adds anything new to the Remote Pilot Airmen Certification Standards. The ACS is published/created by the FAA and outlines what knowledge is required of a remote pilot.

The last change to the Remote Pilot ACS occurred in April 2021, with the addition of operations over people, night flying, remote id, and more.
