Ok Robert. I understand the following. If and only if you can devide the distance by three, three, for climbing, three for leveled flight and three for descent. This I have figured out. Then ofcourse deviding your leveled cruising alt by three to figure out when you should start your descent. That I do understand. What I don’t understand is if it isn’t even. For example. Let’s look at example three once again. Your distance is 4290. I take it this is just cruising leveled alt from point a to point b with not the climb and descent added in? Ok here we go. Our distance is 4290 NM The simple way is if we devide that by three, we’d get 1430 NM. Which we can not do for safety. Ok now II don’t understand the rest of the forumla so when you can not devide a distance of a route by three. Could you go over this part of the forumla one more time? While you do that, I’ll take a look at the link that you had provided that’s also in the flight deck near this area of the flight deck manual. Thanks.

Hello Ron, Please refer to PAGE 45 of the Flight Deck Doc, where this subject matter is discussed in excruciating detail.

So if I were flying west I would start my descent at 120 miles out and 110 miles out for east bound flights. I see that the topcrousising aleveled flight for the falcon is 510. The first even set of figures would be at 480 which devided by thre would equal out to 160 And for east bound flights a level alt at 450 would equal a level cruising alt of 150. Or should I refile for a lower leveled cruising alt? Thanks. Ron and current Leader Dog boz who states "that a service dog beats a cane paws down any day of the week."
