Comment above:
"For the 737-800 this is taken care of with the approach idle..."
Check the engine's acceleration curves: Does Approach Idle avoid the flat portion on the left-side?? Does Approach Idle get the engine "spooled-up" -- over into the pilots' desired
steeper right-side
linear-slope??
Manufacturer contributions are not real good (not so explicit), but the curves shown with industry's
ALAR Briefing Note 4.2 suggest that their "Approach Idle" is NOT into the linear, STEEPER right-side slope: Approach Idle (even according to the manufacturers) is still two seconds behind their estimate for power needed on approach G/S.
