Okay, going out on a limb a little bit here. I don't know a good, easy method of calculating or using winds aloft from the charts. Is there a method or a link to a method that you guys know about? Or maybe some way to use winds aloft in iFly to learn about the subject? The Jeppeson teaching book method does not sink in (ground school.)
There are so many variables I just cannot see how to pick best cruise altitudes, even. One would think it would be intuitive.
If iFly does not have it, can we get it in the future?
