I explained that in post #18.So you tell me, if the elevation of where I flew 1000 feet was 26 feet, how is my top altitude still a negative number? I could understand it if I was out to sea when taking off but I was on dry land each time, and even if I did take off close to water the depth has never been more than a few feet.
If you want to see a higher Top Altitude, you probably have to go to Georgia (or fly from the top of a landfill mountain).
It has nothing to do with your flight altitude, which you can easily see by tapping on the top of the Altitude column in teh flight records.
