ABSTRACT	The NAL QSTOL (Quiet Short Take-Off and Landing) experimental aircraft, ASUKA,is being tested at Gifu Airfield. Flight tests were conducted to evaluate the PAPI (Precision Approach Path Indicator) system, with which Gifu Airfield was newly placed. In order to support the ASUKA´s flight test program, this PAPI has been designed to provide two reference approach path angles : three degrees (CTOL type) and six degrees (STOL type). This paper summarizes the flight evaluation of the PAPI. The NAL experimental airplane, B65, in which a high-resolution type VTR camera was installed, was utilized to obtain images of PAPI lights. The tracking radar system on the ground recorded the traces of the B65 position. VTR images and radar data were then synchronized to confirm setting angles of PAPI lighting units, which can be estimated by the aircraft positions at the instant of color transition of each PAPI light. The results of the analysis as well as pilot comments, such as that PAPI has decreased pilot workload, pred the effectiveness and performance of the PAPI sysytem.
