Hello folks!
Question for those boeing drivers around:
We are performing an approach with flaps 40, we are heavy weight, so we decide to go with Flaps 1-5-15-30(!)-40.
Now lets assume that for some reason we have to stay on 30 for a while. What command speed will you set? Approach one (Vref40+additive), which may be less than Vref30, or such for flaps 30 (Vref30)?
FCTM is quite unstrict with this tellng us that we should go "30 or 40" after 15, and set "Vref30 or Vref40 +additives". So it can be read both as "set any flaps and final speed" and as "set any flaps and RESPECTIVE speed".
Where is the truth?
