The lexicon of air transport has received the influence of terms from other modalities of locomotion, of sciences such as meteorology and ornithology and it has also incorporated loan words from different languages. Although it has been the object of lexicological study in different languages, there are few studies that address the appropriation of this lexicon by non-specialists and no dictionary exists that accounts for the non-technical uses of such lexical units. This article presents the lexicographic decisions adopted to design El lxico espaol del vuelo, a proposal that attempts to record the daily use of Spanish aeronautical words, giving an account of their diatopic, diachronic and diaphasic variation. Specifically, it describes both the selection of materials and the conformation of the lexical database as well as the text macrostructure, the criteria that operated in the lemmas selection and ordering and, finally, the microstructure of the lexicographic articles.
