Maximum angle of descent
Hello all,
I was wondering the other day if there was a particular speed that one should fly for the best angle of descent. Vx and Vy are given, and best rate is Vmo plus spoilers. But say ATC gives you a big shortcut on a really long STAR, so now you find yourself pretty high. How do you determine your maximum angle of descent? Some will say start to configure early and watch the altimeter wind down, and others will say spoilers and FLCH /OP DES. I don't think both methods can be right.
Is there anywhere it's published,or any way to get a rough estimate of the speed required?
