1. An aircraft, comprising: a flight control system for controlling flight of the aircraft, including an engine for producing an engine flow, a nozzle having an axis and located downstream from the engine for releasing an exhaust plume from the engine; a fluidic vectoring controller responsive to the flight control system for vectoring the exhaust plume relative to the nozzle in a desired off-axis vector direction; the fluidic vectoring controller controlling: a fluidic off-take system for bleeding off a portion of the engine flow, the fluidic off-take system having a valve for controlling flow of the portion of the engine flow; an injection system extending from the fluidic off-take system into the nozzle for injecting the portion of the engine flow into the nozzle to change a vector direction of the exhaust plume off-axis as the exhaust plume exits the nozzle; a verification system for verifying that the vector direction of the exhaust plume is substantially equivalent to the desired off-axis vector direction, the verification system comprising: pressure sensors mounted on interior side walls of the nozzle for measuring pressure at the interior side walls; and means for correlating the pressure sensed by the pressure sensors with the vector direction of the exhaust plume.
