A:AnswerThe mavic air 2 can fly up to 3.1 miles above sea level with permission. FAA laws limit drones to 400 feet above your highest point for air safety. The key here is highest point. If you are in a field you can legally fly 400 feet. If you are standing next to a 1000 foot building you can legally fly to 1400 feet (1000 + 400). The remote will warn you at 400 feet. You can go higher but it is you responsibility and can lead to trouble and fines. Trust me when I say 400 feet is plenty high to capture good footage. Any higher you might as well use Google earth.
A:AnswerYes for both. Auto returns to it's take-off location. Must wait till it locks in multiple GPS sat. before take-off to ensure an accurate return when once engage is all hands free. Warns if battery gets low based on how far away from home and prompts to return which can be done via auto return home.
A:AnswerYes. It has two different tracking features (follow me) and several preprogrammed selfish features. First tracking will follow you/stay on you while you fly the drone. The second will follow you at your predetermined angle and height by itself unless it runs into an obstacle.
A:AnswerI found the article and this one uses a different app than sited. The DJI Fly app(Sites DJI Go4 app for Android). The website the information was on did not seem like a reputable source in my opinion.
A:AnswerI imagine it can use whatever size. I've been using a 256GB micro SD card, considering the 4k video files it creates are pretty large. Works great! If there are larger, I don't see why you couldn't use them.
