Pilot’s manual BiGolden2 Version no. 1, from 27.4.2009
surface is detached and the canopy enters a parachutal stall without moving
forward. It will soon stabilise above your head.
- recovery: On releasing the B-risers BiGolden2 automatically returns to
normal flight without staying in deepstall (sackflug) or shooting in front of the
pilot. Let go of the risers smoothly and symmetrically.
Caution: If the B-risers are released unevenly the canopy could enter a turn on
release from the B-stall. If the risers are released slowly and very unevenly it
could start a spin.
5.2.3 Spiral dive
The spiral dive is the most effective way of making a fast descent. Every pilot
should be able to perform a spiral dive and one day you may need to. Always be
aware of your altitude which decreases very rapidly during a spiral dive. The sink
rate reached in a spiral dive can be more than 20 m/s!
During the spiral dive the pilot and glider will experience strong centrifugal
forces: the overload could be more than 3 g (!) which is a great demand on the
pilot. The glider is strained just as much!
- initiation: Smoothly pull on one brake so that the the glider goes from a
normal 360-turn into a steep turn and from there into a spiral dive. The transition
into a spiral dive can be made easier by weight shifting to the inner side of the
turn. Keep an eye on the tension of the control line all the time - reduced tension
signalises an overload of the glider and danger of falling into a negative spin.
- recovery: BiGolden2 recovers from a spiral automatically as soon as the
brakes are released. Release them smoothly and always finish a spiral dive with
safe altitude!
5.3 Special flight regimes
No matter what category of canopy you fly or what level of certification it has, in
turbulence or in strong thermals you may experience all kinds of collapses.
BiGolden2 behaves comfortably in these situations, indeed not only does
BiGolden2 deal with extreme flight regimes automatically, but also offers an
above average degree of safety. Even so, you must follow all safety rules when
practising special flight operations and always pay attention to your altitude!
Before performing special flight regimes remember:
•
practise reserve deployment on the ground, in a simulator, so that reserve
deployment is automatic and efficient.
•
Rapid altitude loss and considerable rotational forces may develop during
unstable manoeuvres. Take account of these factors in the context of reserve
deployment!
