I had heard that airliners will generally glide a 3 degree
glideslope, clean and power off. Something that GA airplanes
have no hope of doing.

If we were on the glideslope "way out", and clean power off, our
biggest problem in the B-707 was slowing to the "gear/flap" speed
without using the speedbrakes which shook the Pax too much.
In the 727, because of the T-mounted horizontal stabilizer, we just
yanked the speedbrake.
