That's the point...there are more drones involved than what are being discussed here that would be affected by such a blanket requirement.
There are, but they aren't the topic of this discussion. And those "other drones" are very much larger, and capable of much larger payloads. They are not going to have an issue with a few ounces for an ADS-B OUT transmitter or the power drain from it.
Again, there are more than DJI drones involved here, including home-builts without any restrictions whatsoever except the builder's ability & budget.
I'm sorry, but there is still the 400 foot flight limit imposed by class of UAS and operator privileges. You claim no restrictions, which is patently absurd.
That 7 watts is transmitter output power, not consumed power. Even with a very efficient final power amplifier, it's going to need at least 10-11 watts or more, and that's for *just* the final transmitter output stage, not including signal generation and driver stages for the final amplifier stage. That's a serious amount of power drain for a small drone and will seriously reduce flight endurance and performance.
I guess you are ignoring all of the electrical budget discussion already posted. In my budget, I assumed just 50% efficiency, and that means 14 watts, not just 10-11W, and still managed to show that it would be an unmeasurable effect on a typical (DJI Phantom 3 Pro) UAS. I ignored the control electronics because those would be a trivial amount of the power requirement. Your cellphone has more processing power than what it necessary for an ADS-B OUT, and it will run for a very long time on a very small battery.
Please stop waving your hands and stomping your feet about a "7 watt radio" and actually look at the system.
At lower altitudes ground clutter has even more of an effect as the signal 'horizon' is that much nearer for the aircraft as well as the UAV.
You are worried about ground clutter when the UAS will be us where the 200 knot speed limit doesn't apply. That's not "at lower altitudes". Please look up 14CFR91.117 and learn. I am off by 50 knots -- the limit is 250 knots below 10,000 AGL. Ten thousand feet. But still, there is a 200 knot limit below 2500 feet (two thousand five hundred) within 4 nm of an airport and under any Class B airspace.
To find a jet going at "jet speeds" you need to be up 10,000 AGL -- which a DJI isn't going to be. Ever.
And they won't be below 500' unless they are departing or landing at an airport nearby, so they MUST be going less than 200 knots there. If your UAS is up where you can find a jet, it won't be in ground clutter anymore, it will be free and clear of the ground.
A 7 watt transmitter will draw effectively the same amount of power regardless of physical size.
That's right. It will draw an average of less than 50mA if it is the size of an elephant or the more realistic size of a pack of cigarettes. I have 5W radios that contain GPS and will transmit their position via APRS that fit in my pocket. Very small. Very light. I have an 8 W radio sitting on my desk here, and it's not very much bigger than a 5W radio. Most of the size of those radios is user interface -- speaker, dials, etc. Remove the speaker, make the "dial" on/off, and you can reduce the size of the radio even smaller.
Why do you think that a radio that weighs just a few ounces and consumes, over the course of a 20 minute flight, about 20mAH, will be an issue for any UAS that would be regulated by any proposed rule?
As to your link, I thought you said that a full 7-watt ADS-B-out transmitter was "easily accommodated"? Which is it?
You didn't look at the link, did you? You just want to blow smoke. The ADS-B OUT radio I linked to would be trivial to reduce in size and install almost anywhere.
Or we could, you know, *not* go apeshit-authoritarian trying to track & trace toy quadrotors
If you actually read what I've written (I know, this is
Go get 'em, Tiger!
I suppose if you can't argue the technical things, go for insult and emotion.
