2.2.3- Chest strap adjustment
The chest strap controls the distance between the two snap-hooks, which
can vary from 35 to 45 centimetres. For the first flight, we suggest setting
the chest strap to around 40 cm and then locating the preferred length in
flight by means of gradual adjustment.
Stability is greater when the chest strap is shorter and tighter. An excessive
distance between the snap-hooks does not improve glider performance
and tightening the chest strap excessively may exacerbate the ‘‘twist’’ ef-
fect that may follow an asymmetric collapse of the glider.
At shoulder strap height, there is a small hook that acts as a shoulder strap
fastener and prevents the shoulder straps from sliding off the shoulders
during take-off. The plastic coupling also holds a practical whistle which
can be helpful in the event of an emergency.
ATTENTION:
Each adjustment must be carried out symmetrically on both sides.
2.2.4 - Seat height adjustment
This adjustment varies the angle between the legs and the back (seat
depth), distributing the loads between the seat and the lumbar area, there-
by providing the pilot with greater comfort.
