    I’m struggling to get the Overspeed feedback in sync with the aircraft. To do so I would need to be able to set the CLS2SIM speed to the IAS and not the TAS.

    Is there any way of switching that ?

    or a preference to have 3 options ?
    1) IAS (Value)
    2) TAS (Value)
    3) Simulator (Overspeed Warning,bool) = True

    Hi Daz

    Does TAS even make sense?
    IAS sure would, as it considers equipment failures, etc.
    Simconnect overspeed warning seemed spotty, kinda unreliable to me at testing, same as stall warning.
    A cent for your thoughts?

    TAS to IAS will be added into the issues list, options are noted as a possible extension of the feature.
    As total alotted feature time for the next development cycle is already at capacity,
    the first could be squeezed in, but the second will have to wait.



    TAS seems to be the obvious selection I totlly agree. I’m not 100% sure if the simulator overspeed warning is monitored as IAS or TAS, but when I set the feedback to a value it never seems to match the sim overspeed warning. even if I tweek the CLS2SIM value up or down its drifts from the simulator overspeed alert.

    if the simulator is using IAS in its calculation in the overspeed:bool variable then setting a IAS value would be the only option.

    I can’t be certain what’s going on, but regardless I can’t get the feedback to initiate at the same time as the sim overspeed warning kicks in. When I get it close next time it drifts in either direction and assume this is because of IAS/TAS difference? Using the SIM’s overspeed variable seems to be the best fix ?

    Thanks for your thoughts on this.

    If adding SIM overspeed bool for feedback to start, you might want to think about using the sim stall bool for the stall feedback also? I havn’t noticed an issue with stall yet. I tend to fly too fast not too slow.

    It’s not a major issue and no rush to put anything in place, just throwing ideas out there, while I start fine tuning my setup.

    Regards Daz
