隨著光觀帶動飛航產業日益興盛之下，最重要的永遠離不開飛航安全。近年有關飛航研究領域包含管理、人因和機械穩定性，然而很少有學術資料探討飛行前的飛航安全宣導影片的用語和內容。本研究著眼在各航空公司打造的飛航安全影片之語言和非語言（藝術層面）的呈現。從YouTube收集到的一共50部短片（總字數27,114）會以語料庫為基礎的多模態框架去分析語言特性、視覺特性、聽覺特性，三種由Machin（2007）提出的面向。每個影片長度約五分鐘（總長度約四小時）。影片謹守自設的評選標準以控制整體品質和效度。本研究採用質化和量化的混合研究方式，以字詞分析軟體WordSmith 7.0剖析量化特性之語言使用方式，如單詞出現頻率、搭配詞、字串，所得之量化結果將用於第二部分的質化分析。視覺語言，如符號意象元素，是以多模態分析法分析。研究成果如下，在空服員安全示範時經常採用「幽默」的技巧；最常出現的安全項目是「安全帶（Seatbelt）」和「緊急（Emergency）」；飛航安全影片看起來如此豐富是因為加入很多與飛航安全關聯性低的元素。透過多模態分析法，飛航安全影片中的符號意象元素、其吸引乘客目光的藝術性，皆可以忠實的呈現，亦有塑造品牌形象的功能。

The aviation industry is booming with the rise of air travel, and the safety issue has become a primary consideration. Research over the past years has mainly examined flight safety factors such as management, human factors, and mechanical steadiness; however, few studies have investigated the discourse of safety demonstration videos before takeoff. The current research paid close attention to the linguistic and non-linguistic content of airline safety videos regarding their linguistic and aesthetic inclusions. Fifty videos (speech data 27,114 running words) collected from YouTube channels were grouped and analyzed in terms of “a multimodal corpus-based framework” according to three main perspectives (Machin, 2007): linguistic features, visual presentations and audio characteristics. Each clip lasts for around 5 minutes (approximately 4 hours in total). Criteria were strictly followed in the source selection process so as to control the overall quality and validity of the analysis. The study adopted both qualitative and quantitative methods, using Wordsmith 7.0 to analyze language use, frequency, collocation, clusters and non-linguistic features. The results suggest that humor is employed in flight attendants’ safety demonstrations, the safety features indicated by word frequency are seatbelt and emergency, and the inclusion of irrelevant components contribute to the content abundance of safety videos. The multimodal corpus-based analysis reveals that the semiotic components of the safety demonstration video are deliberately produced, including the additional artistic value that is considered to better attract passengers’ attention and further influence brand image.
