Plain English Meaning

An agreed system for naming things so everyone calls the same item by the same name. It prevents confusion when a pilot, a mechanic, a chart, and a manual all need to talk about the same piece of equipment or procedure.

Full Definition

The standardized rules used to label and identify avionics components, software versions, databases, equipment models, and procedures so that pilots, technicians, manufacturers, and regulators all refer to the same item in the same way.

Context Anchor

Seen when comparing an avionics display, such as a GPS or flight management system, with an instrument procedure chart or route description.

Derivation

From Latin nominare, 'to name,' and convention, meaning 'an agreed practice.' A naming convention is literally an agreed way of naming things — useful when many different parties need to recognize the same item without ambiguity.
