Hi SOAB,
but it is true: some (=*not all) of our "older guys" took significant more time to feel comfortable with the EASy software. With a bit our routine you will quickly click your way through all the flight and takeoff performance data, but in the beginning it takes ages, because you need to find your way around all the click spots. Those who use computers regularly and with ease, won't have any problem with the avionics.
