Abstract: An aircraft includes a first engine that generates first bleed air flow and a second engine that generates second bleed air flow. The aircraft further includes an aircraft environmental control system (ECS) with a bleed manifold to collect the first bleed air flow and the second bleed air flow, and one or more air cycle machines to perform air conditioning consuming bleed air flow from the bleed manifold. The ECS balances the first bleed air flow and the second bleed air flow output from the first engine and second engine, respectively, based on a bleed manifold pressure of the bleed manifold.

Abstract: A multi-channel control system includes at least a primary control microprocessor and a back-up control microprocessor operable to control a device. The primary control microprocessor and the back-up control microprocessor assert control over a controlled device according to a locally stored method of controlling a back-up microprocessor assumption of control of a device.
