admroz Posted August 10, 2017 Report Posted August 10, 2017 First and foremost, the problem was caused by my mistake. I forgot to retract flaps and in CRZ the plane started to switch between FMC SPD and MCP SPD (probably caused by flaps speed limits). The problem is that while in MCP SPD mode it shows really huge speed value. I am also not sure what should be the proper plane reaction for such a pilot error.

Think maybe X-Plane simulates that if you enable it the failure settings..

I don't know...) and really bad things happened It seems to be not possible to overspeed flaps in VNAV in such scenario (which is good). During CLB there is SPD REST in FMC for flaps and it keeps the limit. Then in CRZ the plane accelerates in FMC SPD mode up to "red tape" and then switches to MCP SPD and slows down, then again FMC SPD, etc.
