2.2 Definitions
Following is a list of terms and definitions used in this AMC.
Alert – A generic term used to describe a flight deck indication meant to attract the attention of the flight crew, and identify to them a non-normal operational or aeroplane system condition. Warnings, Cautions, and Advisories are considered to be alerts. (Reference definition in AMC 25.1322)
Automation – The autonomous execution of a task (or tasks) by aeroplane systems started by a high-level control action of the flight crew.
Conformity – Official verification that the flight deck/system/product conforms to the type design data. Conformity of the facility is one parameter that distinguishes one means of compliance from another.
Control Device (Flight Deck Control) – Device used by the flight crew to transmit their intent to the aeroplane systems.
Cursor Control Device – Control device for interacting with virtual controls, typically used with a graphical user interface on an electro-optical display.
Design Philosophy – A high-level description of human-centred design principles that guide the designer and aid in ensuring that a consistent, coherent user interface is presented to the flight crew.
Display – Device (typically visual but may be auditory or tactile) that transmits data or information from the aeroplane to the flight crew.
Multifunction Control – A control device that can be used for many functions as opposed to a control device with a single dedicated function.
Task Analysis – A formal analytical method used to describe the nature and relationship of complex tasks involving a human operator.
