I’ve mentioned a few times in my column that I have a drone I like to fly (Blade Chroma). I’ve been learning how
to use it as a platform to do amateur science along with photographing my house and my vacations. Many readers
know that in August 2016, the FAA made a pilot’s license for drones (the Part 107 Remote Pilot) available to the
public. Now, every drone pilot making money with his or her drone must first pass this test and receive their license.
Well, in early July, I passed my test (90% of 60 questions) and got my license! I learned the material for free (but
had to pay for the test) and I suspect that many Nuts & Volts readers would like to do the same. So, let me share the
online — and best of all — free materials that I used to learn everything and prepare for the test. Please know that I am
not affiliated with these people nor am I receiving compensation from them. I’m just a happy client.
First of all, a big thanks to Tony Northrup for his excellent free FAA Part 107 sUAS and drone certification study
guide. It’s a great two hour video lecture. However, he did make a mistake at the end. Humid air is less dense than dry
air. Therefore, on humid days your drone props will not be as effective.
Second, hats off to the 3DR (3D Robotics) company. They have over 100 free practice questions online that you
can use to test your knowledge. Some of the questions looked a lot like the questions I got on my test.
Next is Rupprecht Law P.A., which is a law firm with a drone law specialty. Jonathon’s emails asked some very
tough questions that really test just how much you understand about Part 107 and reading sectional charts. Sectional
charts can be a complex mess in some places and you’ll want to get proficent at reading them. If you need help with a
future drone business, this law firm is there to help you.
Finally, being no slouch in making the skies safe for air travel, the FAA has put out a Part 107 study guide. Be sure
you read it as you are prepare for your test.
