During normal operation, which controller is responsible for regulating the High Pressure Pressure Regulating and Shut-Off Valves, manifold Pressure Regulating and Shut-Off Valves, and manifold isolation valves to satisfy Environmental Control System and anti-ice demand?, The Air Management System Auto Controller, The Air Management System Emergency Controller, The Bleed Air Leak Detection module, What is the relationship between the three Air Management Modules installed in the Air Management System Auto Controller?, Each module has unique hardware dedicated respectively to bleed, Environmental Control System and anti-ice functions, The modules are identical, but their functions are determined by their position when connected to the Air Management System Auto Controller motherboard, All three modules perform the same functions simultaneously and use majority voting to determine valve commands, During emergency operation following loss of electrical supply to the Air Management System Auto Controller, which bleed-air configuration is commanded by the Air Management System Emergency Controller?, All High Pressure Pressure Regulating and Shut-Off Valves remain pneumatically regulated and all three engines continue supplying the manifold, Engine 3 remains available while engine 1 is isolated and the right-hand manifold isolation valve is opened, The three High Pressure Pressure Regulating and Shut-Off Valves close, engine 3 bleed is isolated, and engines 1 and 2 remain available for Environmental Control System and pressurization supply, Why is the electronically controlled pressure-regulation set point of each High Pressure Pressure Regulating and Shut-Off Valve lower than the manifold Pressure Regulating and Shut-Off Valve set point?, To keep the manifold Pressure Regulating and Shut-Off Valves fully open and prevent interaction between the two regulating functions, To ensure manifold pressure always exceeds High Pressure compressor discharge pressure, To force the manifold Pressure Regulating and Shut-Off Valves to perform engine bleed-flow balancing continuously, Under what condition does a High Pressure Pressure Regulating and Shut-Off Valve cease to provide bleed-flow equalization?, When manifold pressure exceeds the manifold Pressure Regulating and Shut-Off Valve pneumatic limit, When available High Pressure bleed pressure is insufficient and the High Pressure Pressure Regulating and Shut-Off Valve is driven fully open, Whenever either manifold isolation valve is open, Which High Pressure Pressure Regulating and Shut-Off Valve control function has priority over pressure regulation and engine bleed-flow equalization?, Maintaining minimum Environmental Control System manifold pressure, Maintaining equal extraction from all three engines, Limiting valve opening to prevent bleed-air temperature exceeding 345°C, What is the fail-state distinction between the High Pressure Pressure Regulating and Shut-Off Valves and manifold Pressure Regulating and Shut-Off Valves following loss of electrical power?, The High Pressure valves close, whereas the manifold valves open and regulate at their pneumatic control limit, Both valve types fail closed, The High Pressure valves regulate pneumatically while the manifold valves remain locked in their previous position, How does the Air Management System Auto Controller obtain the information required to calculate engine bleed airflow across the bleed-air jet pump?, From absolute bleed pressure only, From differential pressure measured between jet-pump airflow and pressure downstream of the jet pump, From manifold temperature combined with engine rotational speed, Why does each bleed-air temperature sensor downstream of a manifold Pressure Regulating and Shut-Off Valve contain two independent sensing elements?, One element controls the High Pressure valve and the second directly controls the precooler cold-air valve, One element supplies the Central Maintenance Computer while the other supplies the Engine Electronic Controller, One element supplies the Air Management System Auto Controller for control/monitoring and airflow calculation, while the other supplies the Air Management System Emergency Controller for over-temperature monitoring, During Environmental Control System-only operation, what additional measurements are used by the Air Management System Auto Controller for bleed-airflow calculations downstream in the Environmental Control System ducts?, Manifold pressure, venturi differential pressure and Environmental Control System duct temperature, Only manifold Pressure Regulating and Shut-Off Valve position and engine High Pressure bleed pressure, Precooler outlet pressure and ram-air temperature only
