Abstract : The influence of wind, wind shears and turbulence on the approach and landing tasks of STOL and V/STOL aircraft has become of significant concern for this evolving class of flight vehicles, particularly during instrument flight operations. Flight experiments have been carried out to assess the considerations in alleviating the effects of along-track, a priori wind, including moderate shears, by adjusting the approach glide path for the conditions of the day. A Bell 205A helicopter modified as an airborne simulator and equipped with a modest programmable guidance and display capability was used for the tests, which were carried out in the operational environment of the Rockcliffe (Ottawa) STOLport.
