let’s assume tailwind is 50 knots at TOD, normally I use 3*altitude plus deceleration plus tailwind. For tailwind I use 1nm each 10knots of tailwind. I see this works with a high speed descent (say over 300 knots) but with our CI we have around 270 and it is not enough. Anyone with a better estimation of wind effects on descent computation?
If asking why I do all this when I have managed des , is bcs with trombone style arrivals (snake) most of the times I get major shortcut so to mitigate this I use OP des and stay lower
I am not very smart, so I just use the 3:1 rule, wind be damned, works out pretty well the vast majority of the time. I feel like people who feel the need to complicate this any more than that are the same people whose coffee order at Starbucks is at least fifteen words.
10 years in the 320 series now, in case that matters.
