The QF-104 is a remotely-piloted full-scale drone developed from F-104, which is excellent in the speed performance. Its development program began in 1992 with all the mission by JASDF being completed in March 1997. The drone is operated from the fixed-type ground cockpit using a front view by TV. It has 150msec lag in control. TV camera has limited view angle of 46° in azimuth, 35° in elevation. Those generated difficulties in controlling the aircraft, especially in landing. Several devices were created to cope with the problems, as follows, Landing guidance symbols by vectoring capabilities of the tracking antennas show the deviation from the proper approach-path on the TV screen. Deflection command control laws with heading/wings-level hold mode are proved effective in smooth landing. Yaw string in the nose radome, AOA tone indication, touch down information, and 35 feet over-runway signal are also proved effective.
