Flight characteristics
We recommend that you make your first flights with your new glider in
quiet conditions, in a familiar flying area . A few pull-ups at an easy site
will give you confidence in the PI BI’s handling qualities, from the very
beginning .
Takeoff
Takeoff preparation
Sorting PI BI lines is especially simple . A brief shake will separate the
three riser levels’ few lines . Colour coded A and brake lines make for
very effective final line checking .
Before every takeoff carry out the following pre-takeoff checks:
1 . Reserve OK: Pins correctly stowed, Reserve handle secure?
2 . Harnesses and helmets done up ?
3 . Pilot-glider-passenger connections OK ?
4 . Lines free ?
5 . Canopy open ?
6 . Wind direction and strength assessed ?
7 . Airspace and view clear ?
8 . Passenger ready?
PI BI takeoff behaviour is very smooth and straightforward for both for-
ward and backward launches . Nylon wires and light weight ensure that
the canopy fills quickly and climbs evenly, without hanging or shooting
ahead .
The PI BI is pulled up using both the inner, wide A-risers . This takes
less effort, and the wing will come up very straight . The canopy should
always be laid out in a slightly curved shape, so that all A-lines are
equally loaded during the pull up .
Tip: To get the PI BI in just the right curved shape for takeoff
stand abeam the centre of each wing after you have sorted the
lines; take the brake line and pull it in until all the brake junctions
are tensioned .
Light Wind Takeoff (Forwards)
The PI BI only needs a modest tug in a light wind . It is not necessary
to step back and then ‘run’ into the lines . Lead the glider up with com-
mitted and forward-leaning body weight, but without too much pull on
the inner A-risers, until the canopy is nicely above you . Any directional
correcting during the pull-up phase should be done by going under the
glider, without use of brake . After the correction phase and a look at
