Graphic Air Time Remaining (ATR)
The graphic air time remaining box gives you, at a quick glance, the amount of air you have left. As your air time lowers, the box empties. For example, if the box is filled up to the 45 minute level, you have between 45 and 60 minutes of air time remaining; if the box is filled to the 30 minute level, you have between 30 and 45 minutes of air time.
