July 12, 20178 yr I'm playing around with planning my own route using SkyVector and comparing it to what PFPX outputs. I managed to fly from Berlin to Milan the only problem was that I was above Milan airport at 41,000 ft. Am I the one who's supposed to input a Top of Descent point or did I do something else wrong?

You probably didn't select an arrival or an approach so there was nothing with which the FMS to calculate a descent path. No descent means no TOD. Always check your arrival on the LEGs page at least 100 nm before destination. Dan Downs KCRP

I've had real good luck calculating the TOD using an E6-B. blaustern I Earned My Spurs in Vietnam

I recommend you fly the tutorial flight, it will get you up to speed on all the systems if you're not comfortable using them yet. Cheers, Chris Brand
July 13, 20178 yr For a rough calculation - take your altitude and multiply it by 3! Keep in mind that this is for a constant decent profile but does provide some rough guidance for where your top of decent should be. Example: 40,000 feet. To descend to 1000 feet you would go 39,000x3=117,000. This would equate to a TOD roughly 117nm back from your intended target altitude. Again, not an exact science but it should provide some guidance to you Dave Robertson BE20, BE35, BE02, C560, CRJ, MD80, E190, B777
