## Abstract

An Integrated Aircraft Command (IAC) unifies a VTOL pilot's controls in a single controller or inceptor device to make it possible for the vehicle to be operated in all phases of flight and on the ground using only one component for the pilot's manual control. This results in a cockpit controls solution with less weight and reduced installation footprint compared to traditional systems present in the industry for different categories of aircraft.
