Unlike the Airbus, flap selection has no affect on speed control in the B787 and it's not new
1.it will not reduce to Flap manv speed. Speed window has to be opened and flap manv has to be manually set.
Although I was told some versions of FMC/AFDS had auto setting feature(not verified )
Thanks all, but I don't know guys... This is not what me and my partner (and surprised trainer) are seeing. The FTD is consistently reducing aircraft speed to that flap's min speed upon flap selection with VNAV PTH. We see this behavior if we make selections 5 miles before reaching the Fx symbols on the ND. I think I'll wait until I get to the FFS!
