Advance acoustic PI BI, User Manual

Page: 19 / 50

Suitable harnesses
The ADVANCE PI BI is certified for harnesses in Group GH ( without rigid
cross-bracing - see section «Certification» ) . The suspension points of
the chosen harness should ideally have a carabiner distance of approx-
imately 45 cm ( equivalent to your shoulder width ) and a height of 40 to
48 cm .
The PI BI is neither suitable nor certified for use with harnesses in group
GX ( with effective cross-bracing ) . The use of such harnesses can have a
bad effect on both handling and extreme flight characteristics .
The PI BI was tested and certified with a size M BIPRO 2 harness (cara-
biner height 44 cm, chest strap width 55 cm) . An EASINESS 2 harness,
size M (carabiner height 45 cm) was used for the passenger .
Weight range
PI BI weight ranges for 38 and 41 sizes are given in the «Technical Data»
section . The weights quoted are total in-flight weight . This includes the
body weights of pilot and passenger including their clothes - and ever-
ything else that is to fly (paraglider, harnesses, reserve, instruments etc .) .
Flying at lower or upper weight limits can influence the flying characte-
ristics and handling of the paraglider, but does not affect safety . When
the PI BI is flown in the upper part of its weight range the higher wing
loading results in a higher trim speed, which results in more agile and
dynamic behaviour, and a longer takeoff run .
