Really? Sure it isn't just your own lack of a sense of humor? Ease up a bit and learn to appreciate the humor, without all the fear mongering.People take such post serious regardless of the intent. And then they imitate.
People think that Bryce has really garnered respect by slapping some numbers on his quad and wearing a pilot hat. How many people will read that, slap some random numbers on their rig, and find an old pilot's hat to wear and think they are now a pilot?
You have just made my point again...
Indeed. It is unfortunate that our DJI GO telemetry data does not also feature an AGL altitude at all times, in addition to the height relative to the launch point. There is a barometer in the iPad Air 2, so why not use it to at least display an above sea level altitude, too, after specifying the launch height above sea level? You don't need to be launching from a cliff to encounter this issue. Any launch from the side of a hill or the top of a hill to have clear LOS below you has the same issue.Please note that the AGL (above ground level) altitudes specified follow terrain, so flying your drone off the hypothetical cliff situation is a good example of the need to pay attention to the terrain in your area of flight.
While drone operators are not "pilots", they are being subjected to some of the same rules and the methods of application to flight as aircraft pilots.
This is interesting, because the FAA is almost defining a new class of airspace specific to sUAV craft.
We are on the same page, but just not communicating clearly enough. The FAA guideline is 400 feet above ground wherever you fly. However DJI only measures above your launch point, with no allowance for flying over a lower elevation than your launch point, which is the best way to maintain clear LOS at all times when flying. We don't all live in flat areas. Hills are the best places to fly from! So, the 400 foot guideline is easily exceeded, even unintentionally, because accurate AGL data is not provided in the telemetry during flight.I don't think it quite works that way with the FAA rules. If it did, anyone living and/or operating their UAV 400 feet or more above sea level would be in violation. Hello Las Vegas, Phoenix, Denver, Boise, etc. I believe that AGL is the intended reference.
Thank you! I've been hammering on this issue since day one, as I live on a hill and fly over the valley and flatlands below me. Great for maintaining excellent radio communication with the aircraft, but requiring mental calculations to be aware of the unintended consequences. If I have RTH altitude set to 400 feet, and fly at 150 feet above my launch point, and fly over the flatlands that are 250 feet below me, everything is copesetic, as I am still at 400 feet AGL, until I lose signal, and RTH now ascends to 400 feet above the launch point, and brings the aircraft back at 650 feet AGL over the flatlands!That's pretty much what he said (re: AGL being the reference, but WHICH ground). You may want to re-read his original message as he makes a VERY good point.
What if you are on a bluff overlooking the ocean that's 100ft up from the beach? You take off straight up to 400ft AGL then then move it over the beach below or the ocean? If you stayed over the bluff you would be 400ft AGL, but now that you are over the beach below you cross from 400ft AGL to 500ft AGL (the ground changed, not the quad BTW), and are now out of compliance with the FAA guideline on how high to fly (which is not a rule or a regulation, FWIW).
The DJI Naza will let you do this because it assumes the the take off point is 0 AGL for the entire flight, which in this case is 100ft higher than the beach you are flying over now.
Indeed. Just saying that the DJI telemetry alone won't keep you in compliance with the guidelines, even if you choose to abide by them.Inadequate altitude measurement abilities on the equipment you choose is not the FAAs responsibility. If you're standing on a cliff and fly over the water 250' away, it's your responsibility to understand the implications.
+1!Only in the most politically correct, bizarro world, would I be accused of attacking someone with my post. I don't subscribe to the new school thought police, but thanks anyway. And if someone was offended by my post, let me just say...................... wah , wah , wah!!!
You didn't think the pilot hat and N number joke was funny. I get it. I thought it was hilarious. That's all there is to it. But you think that now some who read that joke are going to go and actually do it. That's even more hilarious than the joke, and I'm laughing out load again lol!!
