    In the B58P, I just got a Black Square failure for Pitot Tube Blockage and I am unable to turn on the pitot heat to clear the blockage.

      After I landed, I cleared the failure and the pitot heat switches were still frozen.

        Are you using a Bravo throttle? You probably have pitot heat bound to that and it's overriding your turning it on. You can tell if a binding is overriding it by looking at your current draw - does it go up when you turn on your pitot heat? If not then a hardware binding is overriding it most likely (happened to me).

          From a post on exactly the same topic for the Duke:

          Wow, you're absolutely right about that. It appears to be a bug/"feature" of the flight simulator, as the input event "K:PITOT_HEAT_TOGGLE" is completely disabled when there is a pitot blockage. Given what I have seen under the hood of MSFS, I suspect that behavior has been there since at least the early 2000's, if not the early 90's. I've been contemplating creating my own elaborate simulation of pitot-static effects, which would solve that problem as a side-effect. Thanks for pointing it out.

            @MiRexer Thanks for your reply. I wish that was the case as it would be an easy fix.

              @Black-Square Ok, great. Is it too late to be considered for some maintenance?
