Flew several of these into ATL for the test phase. It was the KERMT1 arrival. Worked out great. At TOD, the power came back to idle, and down you go. Depending on winds we tweaked the VS with the boards, and at the speed changes, used appropriate flaps. Hit the FAF on speed, and configured. It will make a lazy pilot out of you. THe only issue is, for it to work, everyone needs to be doing it. Get one guy in there who doesn't have an FMS/autopilot capable of doing it and then you're back to "turn right/left, slow down, speed up."
