Why do I get an error message that says “AS Flight Analysis Software cannot find any data in this file to display” when I attempt to open a data file?

This error message appears when the data file you are attempting to view was recorded without a 3D GPS lock. In order to view a data file in AS Flight, 3D GPS lock is required. If your data file was recorded by an AIRS-400 or Vision 1000, you can review the audio and imagery in the Playback Utility since it doesn’t require 3D GPS lock to view files.
