1) I am trying to understand why the No 4 dual fed bus in the B200 has an item labelled "PROPELLER GOVERNOR" when as far as I can see, the primary, overspeed and fuel topping governors are all hydraulic/mechanically controlled; any ideas?
2) The No 1 dual fed bus has an item labelled "CABIN PRESSURE CONTROL"; if this item is lost for example in a No 1 dual fed bus failure, would it only affect aircraft (after BB1180 and BL71 onwards) that are fitted with an electronic flow control unit?
3) On the right Gen bus there is an item labelled "AIR CONDITIONER CLUTCH", if this bus is lost would the air conditioner clutch fail to the open position thus disengaging the compressor?
Thanks in advance to anyone who can help
