For precision control, the keyboard is a more suitable input device than a joystick or a mouse since exact nulling of rates is somewhat easier with keystrokes. | For precision control, the keyboard is a more suitable input device than a joystick or a mouse since exact nulling of rates is somewhat easier with keystrokes. | ||
==== Orbital DAP configuration ==== | |||
As of November 2015, the Shuttle's orbital DAPs are configurable using the SPEC 20 utility. This allows to set characteristics such as the roll rates achieved for a given controller movement, deadbands for attitude and rate holding as well as to switch the nose / aft RCS pods selectively off to conserve propellant. | |||

Note that the DAP characteristics configuration allows to specify unstable or ineffective use of the RCS, thus changes should be entered with care. | |||
