On the Collins EHSI display of my King Air C90B are the letters LIN
centered above the HSI display. I have flown a few other larger aircraft that allowed you to select between Linear and Angular quantities of the FMC but the King Air does not have an FMC so I am wondering what the LIN
is for. Does anyone know anymore about what this is telling me? I can not find any literature in the related manuals of the aircraft. Thanks!
