Are simple aerobatics (loops) permitted in the Silent?
The official flight manual specifically states that aerobatics are not permitted. The structural load ratings of the aircraft are also published. For a kit sailplane, the “manufacturer” is the kit builder and in theory it can therefore be certified by the builder to any level of flight capability including sport aerobatics (the flight test program will need to include the relevant aerobatic maneuvers). During factory flight testing, the Silent was subjected to loops, rolls, and inverted flight (Silent Club only) and had no undesirable handling traits.
