Out of the loop

It’s also important to note that any aircraft above that ceiling would be on normal air traffic control screens and need to be licensed with the FAA (maybe there is an aviation nerd who could expand on or correct that)

Not really a "nerd" but:

In the USA:

Drones are not allowed more than 400 feet above ground level (you can increase altitude if the land starts going higher like on a mountain)

Drones can go more than 400 feet above ground level if you have a (part 107) license and is within 400 feet of a man made structure, up to 400 feet above the manmade structure. (Eg: You can fly 1000 ft if you are within 400 feet of a building and the building is 600 ft high, and you have a (part 107) license; 600 ft building height + 400 ft additional high you can go above = 1000 ft total limit).

Drones that fly within 5 miles of an airport require a LAANC approval (can be done online or via an app). Before the LAANC system existed, you used to not be able to legally fly drones anywhere within 5 miles of an airport (I mean, you could always do illegal flights, I'm sure some people did that).

Drones under 250 grams are not required to be registered nor require a license. (For recreational purposes) However, even for recreational purposes, you are supposed to take a "TRUST" certificate/test that basically is a "I Read The Rules" certificate that they don't really keep track of.

Drones 250 grams or above require a registration that cost like $5 to do online. You'll have to give them any serial numbers. And also mark the drone with a registration number that they give you. And again, if this is recreational only, you still don't need a license, just register and have fun. (But the "TRUST" certificate is still a thing that you're supposed to have)

If you use drones for any "commercial" purposes, regardless of the weight of drone you also need to register the drone, and also you need a (part 107) license when operating for commercial purposes. This includes using it for roof inspection for a company, or even for youtube videos that are monetized.

Also recent regulations require there to be a "Remote ID" system for drones that requires registration (basically drones under 250 grams that are used recreationally are exempt). This actively broadcasts a signal via bluetooth that authorities (or karens) can scan and would show the location it took off and the location where the remote is located.

Authorities probably could already do that before remote ID, but this just make it easier and more accurate.

Most manufacturers already have remote ID system added to new drones above 250 grams, and some manufacturers do not even allow you to disable it.

But for drones under 250 grams, manufacturers don't bother with it, since its not required.

[Btw, I don't think many people really care about FAA rules. They have this rule called "Line of Sight" rules basically you can't fly further than your eyes can see it. Go on r/drones on reddit and basically nobody on that community follow this stupid rule. Aint nobody registering their toy drone lmao]
