And I was hoping I was actually missing something. Too bad there isn't some type of (for lack of better term) ping going out to the ground level to tell the current distance above any object you are over besides distance above the home point. I would find that helpful.
Thanks all for the input.
Aloha santa,
There is a work-around to it all. As Labroides noted, you have to do all the thinking. I live in a multilevel flying environment and have to use variations in altitude to stay legal. I am also on the 5 mile line from a military airfield next to a 2000 foot line of cliffs called Pali. In the other direction is the ocean.
As racer noted, you are allowed to fly 400 feet by and above a "structure". A mountain is considered a structure. Now comes the adaptable part. The Phantoms are able to fly as much as 500 meters above the Home Point. That comes out to 1640 feet, or so. I cannot summit the mountain cliffs behind my house, but I sure can climb a large portion of it and stay legal.
One time, before I started flying the full 1640 feet, my friend and I tried some mountain math and used the Geebax trick above of shutting down and restarting to get another 150 or so feet. It was a lot of fun (and the video is kind of funny), but it is much easier to just change the max altitude.
You do not have to fly the full 500 meters, but you can use the leeway to set the max altitude more than 400 feet above the Home Point if you are flying near a structure. In your case with the 200 foot rise or hill, you can set the max altitude to 600 feet. That way if you are flying and start to go above 600 feet the remote controller girl will tell you that you have reached the max altitude and it will display on the screen. If you want to go the full 400 feet above the hill, you can reset the max altitude to 800 feet (the setting is in meters so you have to do the math first).
The other day, I was making a video of the super high tides we are getting to see how far they are encroaching these days. (Sea level rise is getting more attention in the islands with global warming.) Because I was less than 5 miles from the Marine Corps Base Hawaii Kaneohe Air Field, I had to fly below 150 feet. So I set my max altitude to 140 feet (because if you fly above 150 feet they can make you lose control of your aircraft). It turned out that I never really needed even the full 140 feet. All the interesting stuff was way down on the shoreline.
So, there are some tools that can help but as Labroides said, you have to do the math. Hope this helps!
Aloha and Drone On! |
