METHOD AND A DEVICE FOR CONTROLLING AT LEAST TWO SUBSYSTEMS OF AN AIRCRAFT

A method of controlling subsystems of an aircraft. During a preparation step, at least one global order is stored in a database, each global order including an eligibility condition, and at least one global order including an activation condition, each global order specifying a command sequence comprising at least two actions to be implemented one after another or in parallel by two different members. During an initialization step, an onboard computer determines whether a global order is selected automatically or by a pilot. During an activation step, an onboard computer determines, where appropriate, whether the selected global order is feasible. During an implementation step, and providing the selected global order is feasible, the onboard computer performs the actions specified by the selected global order.
