Anyone have a rough figure for the Vref speed for a zero flap landing, in this case for a 738, or any other commercial a/c for that matter?
I only have data for the -700, but here you go:
speeds (commonly) range from 125-135 knots. The procedure to land with flaps 1 or less with LEDs not fully extended (ie: totally clean wing) is to set Vref40
+ 55 knots. That means your final Vref
speed would likely be in the neighborhood of 180-190 knots.
I've flown no-flap landings in the sim, and it seemed very fast, but not as insane as the numbers might suggest.
