Dear all, thank you for all the feedback I'm really appreciate that, going back to my question really is about the command speed setting (the bug), consider there is no gust correction only head wind component.
Example : the Vref is 130 kts and the head wind component is 8 kts
FCTM :
The minimum command speed setting with autothrottle disconnected if Vref+5knots
then you set
on the MCP Vref+5 which 135, you fly with A/P & A/T disconnected manually at 138 kts
(theoritically) 3 kts above the bug
FCTM :
while the steady headwind correction should be bled off as the airplane approaches touchdown
when approaching to touchdown then you bled off the 3 kts, so as to touch down with Vref+5
Centaurus :
It is my experience that most pilots are reluctant to deliberately bleed off the HW additive and instead assume the flare will do it for them. Well it doesn't always happen that way.
So, would it be correct (procedure) to set the command speed to Vref+5 on the MCP
