I think many of us have noticed the altitude readings displayed on our FPV often appear to indicate inaccurate readings when taking off or flying in the general vicinity to where we're standing as we can estimate the height of objects nearby, even when landing at same location we launched from with the altitude no longer indicating a figure even close to zero. A member on one of the other forums may have discovered that allowing the barometer a chance to warm up for for bit, i.e.: 1-3 minutes, may result in much improved accuracy. No need to turn on motors, only the battery. It only needs to be performed on first battery of flying session as the Inspire will store this data. I understand our flight times are very limited however, unless one allows for a significant cushion, this problem likely has and will be the cause of some incidents. I'd be interested in reading the results of more testing to see if this proves to be a beneficial addition to our preflight checklist.
