Description

This advisory circular (AC) provides guidance for the installation and airworthiness approval of flight deck system control devices, from primarily a human factors perspective.  It does not address primary flight controls, secondary flight controls, or controls that are not located in the flight deck.   This AC addresses traditional dedicated controls such as physical switches and knobs, as well as multifunction controls such as touch screens and cursor control devices.
