It is advisable to calibrate the drone regularly with the Parrot FreeFlight Pro app. If the app displays a window requesting drone calibration, follow the steps shown on the screen.
Otherwise, you can also calibrate the drone manually:
1 - Select Fly & Film in the Parrot Freeflight Pro app
2 - Press Settings, then forecasts and finally calibration
3 - Follow the on-screen animation: this disappears once the calibration is finished. You can then start your flight plan on Pix4D Capture.
