A pneumatic flow-control system and method for an aircraft provide efficient mixing of high-pressure engine bleed air with one or both of low-pressure engine bleed air and ambient air. A controller determines an amount of high- and low-pressure air and ambient air to provide based on ambient air temperature and pressure and a flow rate and temperature of the mixed air for improving engine performance during different phases of flight and for reducing a burden on an environmental control subsystem of the aircraft.
