I an finding that the winds aloft data is unstable. The data changes showing three valid periods. The valid period will alternate i.e. 0000Z, 1200Z, and 1800Z. There does not seem to be any way to control the changes. You have to be careful that you note the correct data and not use the expired data. Is there any way to control this? I don't want to see expired data while in flight.
Also the data window at the top of the screen will not stay expanded. It closes down and you have to re-expand the window to keep reviewing the data in the box. Changing to a smaller scale ( zooming in) to center the circle on the airport seems to solve this.
