FAA Part 107 certification: what it is and how to prepare

Whenever someone asks me where to start if they want to fly drones professionally in the United States, my answer is always the same: Part 107. It is the FAA (Federal Aviation Administration) rule that governs small drones used for commercial purposes, and the remote pilot certificate that comes with it is what separates a hobby from a service you can charge for.

In this article I explain what it is, which rules it requires you to follow, and how to prepare for it, so you can walk into the exam with confidence.

What Part 107 is

Part 107 is the regulation for drones under 55 pounds that are used for anything other than purely recreational flying. If you shoot a video for a real estate agent, inspect a roof or take photos for a brand, you are operating under Part 107, even if the flight lasts five minutes.

To fly under this rule you need a Remote Pilot Certificate. You get it by passing an aeronautical knowledge test at an FAA-approved testing center. You must be at least 16 years old and clear a security screening before the certificate is issued.

The rules that matter most day to day

The exam covers a lot of theory, but some rules I apply on every single flight:

• Maximum altitude of 400 feet above ground level. If you fly next to a tall structure, you may go up to 400 feet above it, as long as you stay within a 400-foot radius of the structure.
• Visual line of sight. You or a visual observer must see the drone with your own eyes during the whole flight. The controller screen does not count.
• Maximum groundspeed of 100 miles per hour.
• Controlled airspace. Near airports you need prior authorization; it can often be obtained in minutes through the LAANC system.
• Flying over people. It is only allowed under specific conditions that depend on the drone's category. By default, I plan my flights so I never pass over people who are not part of the operation.
• Night flying. It is allowed, but the drone must carry anti-collision lights visible for 3 miles.
• Remote ID. The drone must broadcast its remote identification, either built in or through an add-on module.
• Registration. Every drone flown under Part 107 must be registered with the FAA regardless of its weight, with the number visible on the aircraft.

On top of that, if an accident causes serious injury, loss of consciousness, or damage to property (other than the drone) of more than $500, it must be reported to the FAA within 10 days.

How to prepare for the exam

The exam is multiple choice and covers topics that seem far from the world of drones at first: weather, aeronautical charts, aircraft performance, airspace and human factors. A simple method that works:

1. Study the official FAA guide. It is free and it is the basis for every question.
2. Learn to read sectional charts. This is the hardest part at the beginning. It is worth spending several sessions just identifying airspace classes, altitudes and obstacles.
3. Practice with mock exams. They help you get used to the wording of the questions and spot your weak areas.
4. Review weather reports. METAR and TAF formats look like a separate language, but with practice you read them in seconds.
5. Show up rested. It sounds obvious, but a clear mind performs much better in front of a chart full of symbols.

My advice: do not memorize answers. Understand the reason behind each rule. When you are in the field, with wind and a client waiting, what saves you is having understood the logic, not having remembered a question.

Keeping your certification current

The certificate does not expire, but to keep exercising its privileges the FAA requires recurrent training every 24 months. It is a free online course that reviews regulatory changes and key topics. I treat it like scheduled maintenance: it forces me to catch up, and I always rediscover some detail I had forgotten.

It is also important to carry the certificate with you, on paper or digitally, every time you fly, because any authority can ask to see it.

What the certification really brings

Beyond the paperwork, Part 107 sets a way of flying. Before every operation I check the airspace, the weather, any temporary flight restrictions and the emergency plan. That means safer flights and calmer clients, because they know they are working with someone who knows the rules and respects them.

If you are thinking about taking the step, do it calmly and with a method. The certification is not a formality: it is the foundation a professional drone business is built on.

This article summarizes the regulations as I apply them in my work. Before you fly, always check the official FAA sources, because the rules get updated.
