A320 Descent Management - VVDN, too high on energy 

Yes indeed, that's my training style. They learn much faster like that.

It will work a bit further also, but you have to add 1000 ft for every 10 nm more than 50 nm (maximum 3000 ft correction). So at 60 nm (10 nm more than 50 nm) it looks like you are 1000 ft high , but it's notmal. At 70 nm, it looks like 2000 ft high, and at 80 nm it looks like 3000 ft high, all normal. I didn't add that to my method because i doesn't always work and when you are on a mach nr, the whole altitude vs speed situation is very fluid. Also, when you are that far away and you already know you can expect a shortcut, you can just fly below your calculated profile by a certain amount to compensate. You don't need to calculate for more than 50 nm that way. No worries for answering. It's pretty rare someone explains this subject well, and I'm glad to help.

I'm glad you find it useful. Keep up the good work 👍

There are some situations where that will work, but not many. But you can try and see if it works for you.

Good question. The answer is that it depends on your speed. When near green dot speed, the speed will start increasing when you set more than 1000 fpm. To find out what the VS is for higher speeds, do the following: just select OP DES when the speed doesn't change, then observe the VS you get. That VS will be the maximum VS you can set without the speed increasing if you are in V/S mode.

There is no need to calculate it like that. You just multiply your distance by 3 and fly lower depending your speed. You can find my calculation method here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4odUv3zTxb4.htmlfeature=shared

It's 25 nm in that example, not 20 nm. So the 1500 ft extra comes from the 5 nm extra.

In my opinion it's not about being behind the aircraft. It's about not understanding descent management. All videos I post are of people who are not yet ready for a line check. It takes a lot of practice and effort to become good at it.

For 5 nm steps, add 1500 ft. First calculate 20 nm = 6000 ft. Then 2000 ft to slow down (for 250 kts), so 4000 ft. Then add 1500 ft for the 5 nm, so at 25 nm with 250 kts, you should be at 5500 ft.
