By the way if anyone knows where to see this Vtrim speed (trim reference speed) in the cockpit, I'd be amazed.
Not shown anywhere as far as I know. Have had a dig through maintenance data in flight and not seen it.
Only place it’s shown is on the IOP in the simulator. I’d quite like it to be shown on the PFD, as I’m never entirely sure what speed the aircraft is trimmed to when disconnecting the autopilot in gusty conditions. Speed at moment of disconnect? MCP target? Vref + 5? Some sort of long term blended average? All four?
