A77 considering. I did 9starts yesterday, and will do 5 tomorrow chances are it is a real PT6. On start when the condition lever is moved out of ICO, the minimum pressure valve will allow fuel to flow to the FCU, and the min flow valve, roughly 90-110#/hr or around 50% N1. The pneumatic bellows will not allow the fuel metering cup to distribute fuel until P3 air runs through to the fuel topping governor in the PCU . The pressure compresses the bellows, allowing the N1 flyweights to adjust fuel flow to the corresponding selected rpm. If somebody wants to send an email address, I will record a start or two if you will post it here
