Aviation Concepts

Concept refers to an idea or abstraction that represents a real-world entity or phenomenon. It is often used to group related terms and provide semantic meaning, and reduce duplication of text in the definitions.

• In a data dictionary:
  A concept helps organize and relate multiple terms under a common theme or domain. It provides a single, authoritative definition by storing it once, ensuring consistency across all related terms.

• Example:
  Concept: Aircraft
  Aircraft might be included in terms like Taxitime, Takeoff, Landing, Parking Position, etc.

NB!

• Concepts are never defined as data models/entities as part of the ACI Data Dictionary.
