Flight path is calculated for the 1971 mid-air collision at Shizukuishi. The calculation is based on the flight-data-recorder records taken from the Government accident report. The crash point thus obtained shows fairly large discrepancy to the wreckage distribution. This paper reports about the contradiction and a new interpretation is given to the flight after the collision.

Three-dimensional minimum-time turns are formulated and solved numerically as optimal control problems. The formulation covers the drag increase and the lift decrease due to sideslip. Inequality constraints are used to simulate the upper and lower bounds of thrust, angle of attack, sideslip and load factor. A state-variable constraint is included to treat the flight sustaining the corner velocity. Numerical results explain the effect of thrust, sideslip and initial velocity in optimal maneuvers.

Trim, static stability and endurance are discussed about the model airplane and simplified formulas are given for them. Also, wing aerodynamic characteristics are reviewed for Reynolds No. at about 104. Combining these, the reason is estimated why model airplanes have larger horizontal tail (relative to wing) than real airplanes.
