It's based on home point height which is zero feet/meters when you take off. If you fly down 400 feet it will be a negative 400 feet. If your RTH height is set to 100 feet and you pressed it, it would fly up 500 feet, fly to the home point and then down 100 feet and land.
It's using barometer not GPS to calculate height as far as I know.
Right. But if he lands at the bottom, when he goes to take off again, it will reset his home point to the bottom, thus not allowing him to fly high enough to get it back, right? |
