After I updated the Majestic Dash 8 to 1.011, whenever I ask the FO to set an IAS by the MCP wheel after takeoff, the IAS value will start from 0 on pilot's PFD and cycles without stopping on the desided value. I noticed that the IAS value on FO's side doesn't move.

 

Thanks in advance for the help

After I updated the Majestic Dash 8 to 1.011,

 

Anyone else?  You're positive this only happened after updating to 1.011?

 

If you get a "runaway", you can use the command "CANCEL LAST COMMAND" to stop everything in its tracks.

Solved! I'm sorry to have caused worries. This is due to a flag in the mjc84.ini file

[EFIS]
AFCS_FSX_SYNC=1

Thanks for the answer, I was using the cancel command already : D
