I was looking at the UAV forecast this morning and this was the chart. I realised don’t understand how it works. It showed that it was ok to fly when the cloud cover was over 70% but not ok when the cover changed to 80% an hour later. No rain is forecast. All the other parameters remained similar throughout the day. do that(I was going to show a screen shot of the chart but I don’t know how )
Can anyone explain the reasoning behind this?
