Dynon recording G meter
Yes if displayed, NO, if hidden on the EFIS-D10, but they may update this on the next revision for the D10. The EFIS-D10A already as this feature hidden or not, the Min/Max G's are always recorded until reset.
What Dynon wrote in responce to the forum:
Yes, EFIS-D10's do not have the feature you are describing. The EFIS-D10A's do indeed keep track of max/min g's even if the g-meter is not shown, but the D10 does not. It's definitely a feature that should be there. I'm (right now) looking into changing this for the D10. We have very limited codespace on the D10 software, but there's still a chance we'll update this in the near future.
Go to their site, they have a support forum. George
