It must be recognized that there is no definitive listing of abbreviations used amongst WWI aviation historians. Even in official publications there are differences in commonly used abbreviations--both among official publications and within official publications. The partial listing of World War I abbreviations is based on a listing of abbreviations commonly used by authors of various WWI aviation journals, as well as in official publications and is provided with the objective of achieving a sense of uniformity and consistency in the material presented in the Journal.
