A method for controlling an on-screen display operation of a display apparatus with an auxiliary inputoutput terminal. In one or more embodiments, an inertia estimator can generate a torque command signal that varies continuously over time during a testing sequence. The filler neck includes a one-piece seamless funnel member having a tubular body and an elongated tubular member. The display device is coupled to receive the image rendering display commands and is operable, in response thereto, to render an image representative of a runway and a segment of the runway that will be used to land and stop the aircraft during the aircraft landing operation. Such a scheme may prove to be a more scalable solution for a shared file system as the number of processing nodes are increased, because the overhead associated with managing the meta-data does not significantly diminish the performance of the storage system as a whole.
