Altitude rate must have sufficient resolution and sampling to permit the derivation of altitude to 5 feet.\2\ Per cent of full range.\3\ For airplanes that can demonstrate the capability of deriving either the control input on control movement (one from the other) for all modes of operation and flight regimes, the ``or'' applies. For airplanes with non- mechanical control systems (fly-by-wire) the ``and'' applies. In airplanes with split surfaces, suitable combination of inputs is acceptable in lieu of recording each surface separately.\4\ This column applies to aircraft manufactured after October 11, 1991.
