Meta4, very true, although I experience more difference usually. Like yesterday. 1.5 m/s at 3 meters, but 4 m/s at 15 meters and 10 m/s at 90 meters. Btw, very stable camera work at 90 meters (300 feet) with 10 m/s wind and -10C. (Quebec city, QC)
It has everything to do with practical safe flying.Um, what does that have to do with real-time wind speed and a built in anemometer?
The idea is to check the wind before you zoom away with the wind.Also how does that help, when the drone is 1.5 kms away
Didn't mention direction, but that's a good addition. Letting your drone drift to ascertain wind speed seems like the least practical or safe method of determining wind speed and direction. If only wind traveling in one direction and never moved throughout a flight, that might work.You said you'd like some sort of wind speed and direction indicator.
You have one ... put your Phantom up to where you want to fly and flick over to atti, hover and watch it.
The app will show how fast it's drifting.
How your Phantom drifts tells you the strength and direction of the wind your Phantom is exposed to up there.
I can't think of something simpler or more practical.
If you had some additional numbers, you'd have difficulty working out what that meant.
I guess you take flight not within the cover of buildings, trees or other obstructions to wind, as wind at height unobstructed by those things can travel a lot faster than where you starting from. You say downwind, I guess you've also never flown around mountains, cliffs, the beach, etc. You get shifting winds at varying speeds and directions.The idea is to check the wind before you zoom away with the wind.
The direction of the wind 100m up will be the same as you have on the ground, the strength possibly a little more.
If you fly 1.5 kilometres downwind and then decide to check the wind situation, perhaps you'll learn from the experience and be more careful with your next Phantom?
I can't tell how experienced you are but this all sounds like the theoretical stuff a beginner might come up with.But knowing on the fly that you're currently flying in 45km/h wind, traveling North East would help you plan a flight and it's power requirements for a safer journey. From start to finish.
Watch the speed indication in the app and you'll notice it's nice and steady and doesn't jump all over the place.Also the app will show how fast it's drifting, based on what telemetry? GPS positioning? The one that isn't military grade, accurate to like 1-3 metres?
You making arguments over a product that is designed for beginners. An experienced flyer will have other issues and boundaries to push. I've flown in 45km/h winds and the drone wasn't going backwards, but once again that was calculated via other telemetry, and not via an accurate anemometer. Which would be a benefit for all flyers of the drone, beginner or skilled alike. Which was the initial starting point of this discussion. Not if there was methods of gauge rough wind speeds, but having a device included to assist.I can't tell how experienced you are but this all sounds like the theoretical stuff a beginner might come up with.
Any experienced flier can gauge the winds he's dealing with pretty well from what he sees and feels together with what he sees with the Phantom and the app.
If you are flying full speed into 45 km/hr, your Phantom is going backwards at 10 km/hr.
If you are so unaware of the wind around you or the wind affecting your Phantom, you won't keep it very long.
***************The drone is "dumb" and zero ground level is where you've taken off. So over the cliff it'll fly at the same 10m as if over ground where you started. So you'll be a lot higher from AGL under the drone and go into negative height when you descend.
It doesn't and cannot see how high it is, in real time. It's just the barometer from start point.
The only way they can interpret height for drones is AGL ... height above ground level.How does FAA interpret this altitude?
Which is an unknown variable, for accuracy, once you've moved away from start point. Unless you're on a flat earth. Which is partly why, I'm sure, it's a guideline currently.It's all about the height your drone is above the ground below it.
The problem with trying to watch a clip like this in 4K is the broadband speed. I tried watching in 4K, but just kept getting the spinning dots of death. I'm on about 37 Mb/s download speed here which generally isn't bad.
You can download a 4K video (to your SSD?), and watch it offline.The problem with trying to watch a clip like this in 4K is the broadband speed. I tried watching in 4K, but just kept getting the spinning dots of death. I'm on about 37 Mb/s download speed here which generally isn't bad.

Next time start the video then pause it..... go to another page or get a cup of coffee and come back. You'll be able to watch the video without a problem.
Then beware if you are flying from the base of a cliff or mountain-- the drone should fly right into it if your altitude isn't set higher than the physical feature you are flying toward.Not a dumb question at all, as I wondered the same thing as a newbie. But now I can say I have done it many times and no issues. The height you take off at is 0. When you go over the cliff edge it will stay level and still be 5 feet or whatever your altitude was. If you descend below the cliff then you will have a negative altitude reading.
