1 hour ago1 hr Doing the usual VHHX-RJTT, take off RWY13 Track 136 115.5 VOR, climbing 7000 till WHISKY in 1.0.4 TristarDial in FL370, haven't pressed any button to intervene/change. ALT window changes from 7000 ALT to 7200 ALT CAP (while 37000 is in the SELECT ALTITUDE box) and slowly climbs, uncommanded 500FPM. Fine, what ever, we are going to climb anyway. Hit VNAV, plane climbs at 500FPM. Cycle TM button to get the PMS EPR to work, and then we get climb thrust (apparently we shouldn't need to cycle TM button, just hit VNAV). So now in CMD1, TM/VNAV/VOR, happy at 250knots. Plane heads upwards, trim wheel start slowly turning to pitch up, and up, and up. We are now >6000FPM and speed quickly dropping. Stick pushes forward to slow climb rate and gain speed but the trim wheel continues to trim for a nose up attitude for some time. Eventually it all sorts itself out and we doing M0.83 to FL370Anyone else have the trim wheel and stick fight each other? Below picture was borrowed from another post but illustrates the sequence needed to gain altitude.
