I'm not a comp pilot however I know that all the data in the world is of no use if you can't interoperate it and use it effectively regardless of what your doing; there are pilots and there are aviators; pilots drive aircraft through the sky, aviators fly as they were born with wings; when was the last time you saw an eagle looking at his vario?
