I need help with the 787

I got it now. The reason it didn’t make sense to me was:

  1. I was expecting it to engage once it hits the first lower alt restriction

  2. It’s very buggy for me. I just did another one this morning and apparently you need to be within a certain alt distance between the lower alt and your current alt. It won’t do it from cruise alt like some of the other planes are capable of.
