Transfer Surface Drawing (Japanese).pdf

This is a technical diagram illustrating airfield layout specifications, specifically depicting runway configurations and U.S. military construction area parameters at what appears to be a Japanese facility.

The diagram provides two cross-sectional views with dimensional specifications. The primary illustration shows the main runway (主滑走路) and secondary runway (副滑走路) with a 150-meter shoulder area (ショルダー 150m). A transition surface (転移表面) approximately 25 meters in depth is identified, with elevation changes marked at 1.0m, 2.0m, 3.0m, and 4.0m intervals indicated by a red directional arrow. The U.S. military construction area (米軍工事エリア) is marked with diagonal hatching in the legend. The lower cross-section detail illustrates the transition surface profile at approximately 25 meters, showing the slope relationship between the military construction area and the adjacent terrain with clearance and slope designation indicators (主滑走路、急陸帯).
