Jamie, Yes, the hydraulic system leaks continuously, even during flight. We had three real-world Saab 340 captains as consultants on this project, and they all confirmed that the system leaks to the point that the pump will run 2-3 times per hour. Keep in mind that the amount of fluid lost does not have to be significant to have the pressure drop to the point of tripping the pressure switch. As to the "details" when recreating the problem... it is very helpful to know what steps you took just prior to the issue occurring. ie. does this only occur on the first flight?, Was the Saab loaded when the sim was first loaded, or was there another aircraft loaded first?. Does this only occur after takeoff, or only in flight?, Were the flaps extended or "in the process of extending? (same for the gear). Situations and circumstances that are repeatable to create the problem are what we are looking for.
