Was testing the waypoint feature out today with my iPad mini3. Flew to 4 points at slightly varying altitudes; none less than 40ft from ground. Set the system to start. It flew to first wp fine, then to the second wp about 20ft above trees its elevation was too low, so had to abort by flipping the mode switch to 'P'. You would think I would have clued in after a month of testing with Autopilot and their app constantly popping up windows to verify current altitude reading....
Nonetheless, I just figured I did something wrong, so flew 4-wp path all same altitude and saved to favorites this time in case I wanted to redo. Started the system, all was well...wp1, wp2... on way to wp3 it started losing altitude [emoji37][emoji37][emoji37]
I managed to disable about 3ft from the ground...whew! [emoji37]
Then it hit me, my iPad doesn't have barometer so it's relying on the bird. The bird isn't very accurate, especially when path elevation changes.
Just a watchout for those either flying close to objects or locations where elevation changes. If you use iOS, Iphone6/6+ and iPad Air2 all have barometers. iPad minis do not.
