Flying speed = mcp speed + 10. How to solve this ?

Hi all,

Does anyone know where in the aircraft.cfg file or in the airfile the connection MCP speed and flying speed can be adjusted ?
I use the Project Magenta MCP and below 11000 ft the aircraft flies 10-15 knots faster than the MCP speed.

Above 11000 ft it is correct.
Because I only use the MCP speed at approach it doesn't matter if it applies to above 11000 ft too.

As there is little support for PM and the setting I am looking for is general I posted it here.
LNAV and VNAV speeds are correct, just the mCP speed below 11000 ft.


Thanks for all suggestions.

Found the cause : turbulence...

Disable all turbulence in your addon weather engine.
Disable turbulence in Fs.
Fsuipc : change the turbulence settings to 50% their value
Fsuipc : inside Fs --> Enable surpress Guts/Windshear/Turbulence

Now the aircraft will fly the mcp speed below 11000 ft and at approach.
