In the detailed photo, adjustment n° 1 changes the angle between thighs and back (seat depth), distributing load between seat and the lumbar area and
thus improving pilot comfort.
Adjustment n° 3 is principally used to alter the angle between the torso and the vertical. Adjustment n° 2 and n° 4 are useful for fine back adjustments, but
they are secondary adjustments that improve contact between the harness back and the pilot’s back, improving support and comfort.
Adjustment n° 5 acts on the thigh-bone angle.
If you wish to work on the adjustments, the strap should be loosened before you set it to the point of optimum comfort. Once you have completed these
steps, tighten the covering strap again in order to lock the adjustment setting.
2.3.2- Shoulder strap adjustment
Adjustment of the shoulder pads compensates for the variation in pilot height, and the adjustment buckle is located in front of the pilot’s shoulder. The
shoulder pads also bear part of the weight of the upper body for improved comfort. We recommend adjusting the shoulder pads so that they fit against your
shoulders without being too slack or too tight.
