This paper concerns the horizontal tail volume of T-tail equipped on PAR-WIG vehicles, capable of OGE flight. There are few previous papers, available to the author, showing explicitly the following facts. First, the tail-volume ratio is excessively larger than conventional airplanes. Second, what are the main factors having influence on the first fact for the said vehicles. Third, how different are the role of the said main factors between OGE and IGE flights. This paper satisfies these points.
