While using the synchronized playback feature in AS Flight and the Playback Utility, I am able to review inertial data for all of my flights; but, I am only able to play back audio and imagery for a couple of flights. Why is this happening?

Due to the large amount of memory space required for video data, more inertial data is stored than video data. Regardless of size, the SD card stores 200 hours of inertial data, but the amount of video data depends on your SD card size and recorder.

AIRS-400

• 128 GB SD card: Retains 10 hours of video data

Vision 1000

• 16 GB SD card: Retains the last 4 hours or 10 power cycles’ worth of image and audio data.
• 32 GB SD card: Retains the last 8 hours or 10 power cycles’ worth of image and audio data.
