The violently thrashi ng wings in a full stall free the cravat in most cases. A full stall is however an extreme manoeuvre and can only be half controlled by someone who has practiced it once before. The same situation in less height clearance requires the immediate throwing of the reserve parachute. In safety training it is repeatedly noted that the decision to throw the reserve parachute is usually taken too late. At least on course there is luckily the radio to give the instruction with, but the accidents over the last months prove that this is a general problem.
Many modern gliders have a fast impetuous tendency to open side tucks.
As the glider in this instance does not tuck dynamically from the front but from the side towards the middle of the glider, this type of tuck has more potential to cravat. Even if a cravat does not occur, the side tuck leads to another turn movement. As the weight of the pilot still moves in the direction caused by the original tuck when the counter tuck throws the glider in the other direction, there is also a twist danger which should not be underestimated. The whole thing can cost 30 - 50 m height loss and is extremely dangerous in the vicinity of the ground. A counter tuck can only occur when the original tuck puts the glider in a dynamic turn movement.
