There seems to be a lot of confusion on this certificate. A few people have kind of ridiculed me for having a certificate but not having flown a drone.
To
legally fly a drone
in the US for
commercial purposes, you first have to take FAA exam called
Unmanned Aircraft Systems (UAS) Drone Knowledge Test.
Here is where you start. If you are a hobbyist, then you
do not need to bother with this, but there are still of course rules you have to follow.
This is the official FAA study guide. And there are more books you'll need. For the type of questions (these are actual questions in the exam), check
here and
here. Attached is my temporary certificate, called "Airman Certificate".
As it relates to you, Simmo, no one can sign off on anything. Again, the key determinant here is for what purpose you fly the drone Is it for fun? If yes, then you do
not need this certificate. Are you taking photos of recording video and charging someone for this? If yes, then you
do need the certificate. You go to an FAA certified facility, usually, a flight school, pay $150+ and if you get 80% of the 60 questions right, you've passed. Now you can legally fly a drone for commercial purposes.
Another caveat here; say you do
not have a certificate but you want to fly a drone commercially? Have a person who has one stand a few feet away from you and watch your every step, so they can grab the RC and save the day.
