Hello everyone: Recently I confused about a question......The Speed limit when at and below barometer 10000ft is 250kt for the aircraft,can this limit is permitted to modify by the pilot? For example, I want to use the limit in 240kt,how can I do the job? Is there any selection in the MCDU about this modfication? Thank you very much !Best regards!Stephen Sunwo3.23

Why don't you just use the airspeed control to dial in your desired airspeed on the MCP, as opposed to using FMS Speed?That is the way I normally operate the aircraft. I don't know the last time I used FMS Speed below 10,000ft.
