GumidekCZ Posted June 27, 2023 Posted June 27, 2023 (edited) BUG =>When flying, Engine Crossbleed or APU bleed unable to produce enough RPM. Min 60% needed to run electric AC generators. On top, APU bleed shows AMAD PR warning (AMAD hydraulic pressure low) but at the same time, hydraulic 2A and 2B are well pressurized - even if I start to maneuver wildly and start to operate flaps. According to Hornet NATOPS manual, both ways are solution to drive AMAD system (fuel, power, hydraulic pressure) if engine is not operating and can freely rotate. A) Good Engine RPM above 84%, engage Engine Crank Switch - L or R of shutdowned engine to open ATS valve to pass bleed air to AMAD and rotate it. B) Hold 10 sec "HYD ISOL ORIDE", start APU - ON, Pressurize APU ACCUM by holding 10 sec "HYD ISOL ORIDE", engage Engine Crank Switch - L or R of shutdowned engine to open ATS valve to pass bleed air to AMAD and rotate it. By NATOPS instructions, the pilots are instructed to use (B) - engine crossbleed to drive AMAD of the failed engine (Right one), if are able to. A) - APU bleed, is last solution. CROSSBLEED_RPM_BUG.trk APU_bleed_RPM_BUG.trk Also I wonder, why we are missing RPM info here (rpm dispalyed on EFEI), another bug? Yes I guess. Edited June 27, 2023 by GumidekCZ 2 2
