Attopilot records over 70 flight data parameters at 5hz into its "black box" aka log file. Using ground control software we can upload the log file into google earth to visualize the flight track. Here's a 3D screen shot of the flight path in google earth. The white path indicates remote control mode while the red indicates autonomous mode. You can see on the flight path where we retook radio control at the crest of the flight pattern.
