An environmental control system (ECS) (200) for a multi-engine aircraft includes a controller (201) configured to switch the ECS between a plurality of operating modes. The plurality of operating modes includes a first operating mode configured to receive bleed air from each engine (209a, 209b, 209c, 209d) of the aircraft in a first environmental condition, wherein the pressure of the bleed air is about equal from each engine. The plurality of operating modes includes a second operating mode configured to receive bleed air from at least one engine of the aircraft in a second environmental condition, wherein the pressure of the bleed air is different between at least two engines.
