The objective of this stage is to make sure the pilot safely can fly advanced soaring, also under pressure as in displays, demonstrations and competitions. This stage has turbulence and small margins as key words. One must be prepared to be forced to operate close to the safe operating limitations for the both the equipment and oneself. Even while one certainly should give both equipment and oneself good safety margins, one must be prepared for the possibility that those margins may be passed. A thorough knowledge of emergency procedures, such as recovery from asymmetric and symmetric collapses, stalls, spins, spirals, and surges, as well as use of parachute, is very important. One must have a thorough knowledge of performance curves and correct flying speeds (speed polars), use of accelerator (speed system), design limitations and load factors. Advanced soaring requires the ability of fast and accurate evaluations of conditions and situations combined with fast and precise manoeuvring. There will be situations with little time for balanced decisions and wrong reactions. One must be prepared by careful planning as well as one always must be ahead of the situation, so that in critical situations one gives the right reaction without wasting time. One must have highly developed skills and a thorough knowledge in order to gain maximum performance. One must, often close to the terrain and in turbulent conditions, master all types of turns combined with low speeds, and also keep a close watch of terrain and other traffic. It is warned against extreme conditions, because of the enormous forces that may be present. Regardless of pilot skill and experience one may easily lose control. Structural (equipment) failures can also happen. One must never overestimate oneself or the equipment. If one meets strong turbulence, one must not panic and try to avoid it by sharp turns or high speeds, since this increases the possibilities for loss of control (or major collapses). Correct manoeuvring in strong turbulence is moderate speeds and flight straight ahead or shallow banks if necessary. Other dangers are stalling or frontal collapse, and loss of control close to the terrain. If this happens, the correct reactions are vital. That is, in case of a stall first reduce the angle of attack by raising one’s arms, control the ensuing surge of the canopy, then wait for speed to manoeuvre and then avoid collision. In case of a frontal collapse, this is to increase angle of attack and if necessary counter any tendency to turns and then avoid collision. One should also avoid flying alone.
