A reference grammar of radiotelephony in air-ground communication

Abstract

The study aims at demonstrating the entire reference grammar of radiotelephony and its distinctive characteristics as well as the conceivable deviation occurred at four domains; namely discourse, lexicon, syntax and morphology, in order to explain and describe the nature of sublanguage performed in the specific settings and purposed through a technological equipment, the intimate relation between language, participants and social encounters demonstrating in discourse structures and linguistic elements as well as the nature of language users who manipulate the language to correspond their basic needs of social interaction in order to effectively accomplish the deemed communication goal. The objectives of the study are to construct the reference grammar of radiotelephony in air- ground communication in four linguistic domains; discourse, syntax and morphology and to compare the constructed reference grammar with the actual usage. The study is conducted with two set of data; one is the data of prescribed or defined language accumulated from Manual of Radiotelephony (2006) issued by international Civil Aviation Organization (ICAO) to describe a reference grammar or the norm of linguistic patterns of radiotelephony and two is the data of actual language in air – ground communication collected from cockpit voice recorder (CVR) acquired from two websites which are http:aviation – safety. Net and http://www.tailstrike.com accordingly from year 1994 – 2004 to discover the deviated linguistic properties occurring in actual air – ground communication. The steps of analysis to examine the data from two sources are strictly and separately conducted under the same specific frameworks and criteria. The main findings of the study has illustrated that reference grammar of radiotelephony is truly represented in rigid set of linguistic properties at all domains acquires from the minimum necessities of the natural English language to create its unique characteristics which some do not exist and commonly determined as ungrammatical features in its corresponding language. The variations in the actual usage are solidly evident at all domains, but there is o absolute indication that they largely occur in syntactic and discourse levels as hypothesized. Most of the evidences illustrate that additional features are commonly from the existing conventional properties from the regular language because of the acquaintance of the customary of the regular patterns which the speakers automatically perform at some points as well as to efficiently fulfill the communicative needs. Therefore, there is a great tendency that radiotelephony will be more united with its corresponding natural language as well as to grow out of its origin since there are also some descriptions expanded from constructed reference. In short, radiotelephony is a sublanguage that continues to develop at all linguistic domains by acquiring more of the governed linguistic properties of natural English language together with extending some features from its confined and unique linguistic patterns.
