The anticollision light has to be visible from three miles away. I could see that being excessive and disruptive for certain urban use cases.

Also... weight is not a useful metric. A 1lb rock has very different ballistic properties than a 1lb feather. A typical 9mm bullet weighs 0.01lbs.

Lots of safety concerns are brought up, but I'm really curious how drones will play out in conjunction with noise and NIMBYism. Drones are loud, so I can't imagine that commercial drone activity (Especially at night) will happen without heavy pushback from locals. NASA did a study and found that the noise drones make is perceived to be more annoying than those from cars [1]. They acknowledge noise-based pushback as a…

You can barely hear (or even see) a small drone above about 100m.

Since this is about objects falling from a certain height, yes, weight is a useful metric for rough safety estimates.

A bullet does damage because it holds a lot more energy from being accelerated - a 9mm bullet will go around a mile up before falling down (source: MythBusters). Two 500g boxes dropped from a likely much lower height will have a similar effect (concussion?) when dropped on a pedestrian regardless of the contents, except for a few outliers. Even for small, heavy objects (like a 1kg camera lens) the load would be spread by its enclosure unless it separates mid-fall.

I wonder if they could deploy something like the airbags they had on the mars rover that bounced down, perhaps with vents allowing air to squeeze out on impact like a crumple zone and cushion a blow if it were to land on someone.

Yeah this seems aggressive. At that brightness it'd be like having street lights flying down your block. Also seems like lights that bright might use a prohibitive amount of power?

Good. The US government has been restricting commercial operations of drone development for far too long. Many companies that were US-based are moving their operations overseas where the laws are more reasonable (Australia and New Zealand, for example).

This is a simple and reasonable step in the right direction. Open up legal operations for the smallest category and begin collecting data. It can help pave the way towards larger operations in a safe way.

I doubt Amazon drone deliveries are what the FAA was considering with this proposal. More than likely, DJI Spark type of aircraft is what was considered where the pilots are looking to acquire video footage. Although a quick lookup shows the Spark to be slightly heavier than 0.55 pounds. That thing is tiny, so if it doesn't qualify for this proposed rule, then the crafts that do qualify would be more along the lines of toys. I was under the impression that the Spark was just about the smallest useful drone available. By useful, I meant can generate a decent quality image.

I don't think that's a NIMBY - pretty sure people not into drones will just be against the noise in their backyard or other peoples backyards.

Right, but a box with a 1lb rock in it, and a box with 1lb of feathers are going to fall from the sky to your head about the same.
