The surface position indicator display shows the movement of the airfoils during the aerodynamical part of the flight. It can for instance be used to check how close, dependent to trim, the elevons are to saturation or how stable the spacecraft is. | |||
(Note that since the Shuttle control surfaces are not driven by the stick but by a digital autopilot which takes the stick input as target, it is near impossible from the feedback to control inputs to gauge whether e.g. trim is off or not, so monitoring the display to ease the trim load of the elevons via body flap and/or speedbrake is important.) | |||
