The first ALFLEX (Automatic Landing Flight Experiment) landing trial was conducted on July 6, 1996 with success and 13 landing trials in total were completed by August 15. As the ALFLEX has employed unique and unprecedented features and its trials were conducted in a foreign country, one of the most crucial themes of the program was to establish the methodology for such and experiment. In this paper, activities toward and during the flight test such as setting the experiment conditions, planning, preparation, the procedure on the trial day, the method of the trials, communications links, as well as operation of the VTOL (Vertical Takeoff and Landing) helicopter and the chase helicopter are summarized. Also, the outcome of the flight trials is explained. Conclusions of the ALFLEX flight trials are given with regard to the goals of the program as: (1) the flight data confirmed performance of the control, guidance and navigation system, and thereby established that the automatic landing technology used for this type of unmanned vehicle is appropriate; (2) data of the low speed flying characteristics of the vehicle having a shape of the HOPE were collected; and (3) flight test methodology incorporating a scaled model vehicle by utilizing a stepping up procedure including hanging flights and mathematical models to the full extent has been demonstrated.
