We dont need no little computers helping us out. Granted we have to constantly adjust our decent rate and usually end up at the required altitude miles before the assigned fix but we get there, oh yeah, we get there. |
Yep...we Airline pilot types would be lost without the FMS...Personally I prefer the green needles and 3-to-1 rule. Add a fudge factor every time for my lack of pilot skills and I make it every time LoL

Another method, probably way too inefficient for jets:
(Altitude to lose / 1000) X 3 = NM distance from restriction to begin descent Ground speed X 6 = Descent rate needed to make the restriction in the above calculated NM distance Example: Need to lose 10,000, and are currently 40 miles from restriction (10,000 / 1000) X 3 = beginning of descent required 30 miles from restriction 400 KT Groundspeed X 6 = 2400 fpm descent rate required to lose 10,000 in 30 miles. |
I've always halved the groundspeed...ie 400 knots equals 2K fpm. Works every time and it's easy enough to do in the head!

Umm, just descend to the altitude right away haha

and for the super lazy, the 170 will create that glideslope, then follow it down for you. it's great when they tell you to descend via the STAR, and you just put the lowest altitude in and watch the magic box do its thing. |

I often get this type of crossing restriction coming into ABQ. I know where I am in relation to the airport (using a wypt for the airport) and make sure that I am at whatever altitude they assigned prior (basically pen and paper like you say). The trick in my airplane comes from the descent profile. Do I figure out a nice long near idle descent or just dive and drive at the last moment? Hummmm....decisions, decisions. I can't wait to get my hands on some of that descent profile FMS type stuff those fancy airplanes have in them! :)

In the words of Martin Lawrence, "DAMMMNNN GEEENA!" Is that rate fairly normal for freight folks? I like it. |
Thanks for all the answers everyone!
