A method for supplying pressurized air to an aircraft includes that bleed air is bled from a portion of a turbomachine of the aircraft and a thrust output of the turbomachine is increased to increase a pressure of the bleed air in a predetermined environmental condition. The method also includes that modes of an environmental control system (ECS) are switched from a first operating mode configured to receive bleed air from each engine of the aircraft in a first environmental condition to a second operating mode configured to receive bleed air from at least one engine of the aircraft in a second environmental condition. The method further includes that engine thrust is increased in at least one engine and engine thrust is reduced from at least the other engine to maintain a constant total thrust when the ECS is in the second operating mode.
