ED Decision 2003/13/RM
Depending on the launching method(s) for which certification is requested, the sailplane must be fitted with one or more launching hooks complying with the following:
(a) Each hook to be used for aerotow launching must be –
(1) Designed to minimise the possibility of inadvertent release, and;
(2) Installed to minimise the possibility of dangerous upsets during aerotowing (see CS 22.151(a)(3)) and to produce a nose-down pitching moment on the sailplane under the conditions of CS 22.581(a)(3), but with an angle of not more than 25°.
(b) Each hook to be used for winch and/or auto-tow launching must be equipped with a release device which is automatically activated when the sailplane overflies the towing winch or auto-tow vehicle.
(c) The release control system must be designed to actuate the release mechanism of each launching hook at the same time, where more than one launching hook is fitted.
