To evaluate the flight safety of the planned Aogashima Island heliport located on a cliff top, local wind field around the planned heliport was investigated by the Toho Air Service Co., LTD. (Toho Air Service), the Japan Weather Association (JWA) and the National Aerospace Laboratory of Japan (NAL). This investigation was arranged by the Toho Air Service and included a numerical simulation analysis of the local wind field, and a flight test. The numerical simulation analysis conducted by the JWA provided an accurate picture of the general characteristics of the local wind field, and was used to identify situations in which turbulence was likely to occur. In accordance with the results of the numerical simulation analysis, the flight test was conducted using the MuPAL-epsilon NAL research helicopter. This flight test enabled the successful measurement of atmospheric turbulence around the planned heliport. Thus the influence of the wind field on flight safety was effectively evaluated using both numerical simulation analysis and the flight test results.
