I am at loss reading this topic. !
Guys, my 767 has never missed TD. Plus it is my best plane in the descent.
In Vnav all the way down, the aircraft follows the descent path, if a little early on the bug, it waits raising the nose some, or accelerate the descent to keep up. My 57 and 77 never miss TD, but are early on the descent. dont follow the path like the 67 does.
Yes, indeed, it is a nice aircraft to fly!  8-)
