The FAA has announced a new list of rules for both commercial and hobbyist UAS operators, which can be found HERE. In the most basic terms, the FAA has made it a lot easier to become a commercial drone operator.
Before part 107, the lengthy list of rules made it so that at least one person in the company had to be an actual pilot. The FAA has taken back that restriction and now there are two different sets of requirements for both first time pilots and existing pilots.
To get on board as a first time pilot you must meet these qualifications:
Be at least 16 years old.
Be able to read, speak, write, and understand English (exceptions may be made if the person is unable to meet one of these requirements for a medical reason, such as hearing impairment).
Be in a physical and mental condition to safely operate a small UAS.
Pass the initial aeronautical knowledge exam at an FAA-approved knowledge testing center.
You will have to go to an FAA testing center to take a test encompassing standard aeronautical knowledge such as: Weather, performance and airspace classification. After that, you will create an account on IACRA, input your passing test score, (most likely a 70 or higher) and then wait for the FAA approval. During this time, you will be vetted by the FAA to ensure you can pass a background check. If you pass FAA standards then you will be mailed a Remote Pilot Certificate, which is good for life.
For existing pilots, the process is much the same. You first need to take the FAA training course located here. Then on your IACRA page, you need to apply for your Remote Pilot Certificate. Once you have your application, you need to validate your identification through a FSDO, DPE, ACR, or CFI. If everything is in order, they will sign off on the application. After that, all you need to do is wait to receive your Remote Pilot Certificate in the mail.
