CAA ORS9 Decision No. 1

(a) If the sailplane is equipped for winch-launching, or auto-tow launching, such launches must be demonstrated at speeds up to V_W, without: 

(1) difficulty being experienced in maintaining the wings at zero bank angle when leaving the ground and in effecting a release; 

(2) control forces exceeding those given in CS 22.143 or excessive control displacements; 

(3) excessive pitching oscillation; 

(4) push forces during the climb. If a trimming device is fitted, the position used during the climb must be stated. 

(b) Tests must be carried out with crosswind components not less than 0.2 V_S0 or 15 km/h, whichever is the greater. 

(c) Tests must be made for each location and arrangement of the release mechanism and for each configuration for which certification for winch-launching or auto-tow launching is requested.
