mraviator Posted January 16, 2022 Report Share Posted January 16, 2022 Setting takeoff V speeds used to work. Now, after pressing send and speeds turning magenta, for a second or two, I get VSpeeds Deselected error every time and they are not transferred.

leha74ru Posted January 28, 2022 Report Share Posted January 28, 2022 (edited) compare the navigation databases on all fms (there should be the same active one) and weihgt fuel (PERF-PERF INIT) Edited January 28, 2022 by leha74ru 1 Quote Link to comment Share on other sites More sharing options...
paul_lbg Posted January 28, 2022 Report Share Posted January 28, 2022 Also sometimes you need to align the IRS in all FMC's, not just in one, same goes with the takeoff page Quote Link to comment Share on other sites More sharing options...
kecm80 Posted February 1, 2022 Report Share Posted February 1, 2022 i got VSPEEDS deselected error one time and got crazy, i figured it out that in the takeoff page, where you put wind, oat and QNH, the last one, QNH was at the right value but not inserted by me. i think you have to put your QNH value in via scratchpad even if it's showing correctly (and you will notice that the font is changing) bb Quote Link to comment Share on other sites More sharing options...
