Paradigmatic Ambiguity in Flight Deck Communication

Abstract

In aviation communication, where accuracy and safety are crucial, any slight variation in words can have severe operational implications. This paper addresses paradigmatic ambiguity — a type of semantic ambiguity arising due to the substitutability of words within the same syntactic slot — in aviation communication. Based on paradigmatic semantics theories and pragmatic linguistics, this study investigates lexical substitutions, near-synonyms, and terminological overlaps as miscommunication causes between air traffic controllers and pilots. The study uses examples from ICAO phraseology, aviation manuals, and actual incidents to demonstrate how language choices may cause different interpretation and operational failure. It further argues that while controlled language in aviation reduces semantic vagueness, non-standard or everyday lexical substitution is a pragmatic hazard, especially under catastrophic or emergency circumstances. The article ends by proposing solutions by way of more rigorous lexical field control, targeted training in semantic awareness, and on-line communication surveillance. This interdisciplinary analysis weaves together linguistic theory and aerial safety and offers practical solutions derived from paradigmatic structure and pragmatic deployment.
