COSY 2 HF
Big ears is a moderate descent technique, achieving about –3 or –4 m/s and a reducCon in ground speed of
between 3 and 5 km/h. EffecCve piloCng then becomes limited. The angle of incidence and the surface
wing load also increases. Push on the accelerator to restore the wing’s horizontal speed and the angle of
incidence.
To acCvate big ears outer line 3A3 on each A risers and simultaneously, smoothly pull them outward and
downward. The wingCps will fold in. Let go of the lines and the big ears will re-inflate automaCcally. If they
do not re-inflate, gently pull on one of the brake lines and then on the opposite one. We recommend that
you re-inflate asymmetrically, not to alter the angle of incidence, more so if you are flying near the ground
or flying in turbulence.
5.3 B-LINE STALL
When you carry out this manoeuvre, the wing stops flying, it loses all horizontal speed and you are not in
control of the paraglider. The air circulaCon over the profile is interrupted and the wing enters into a
situaCon similar to parachuCng.
To carry out this manoeuvre you have to take the B-risers below the maillons and symmetrically pull both of
them down (approx. 20-30 cms) and then hold this posiCon. The iniCal phase is quite physical (hard
resistance) which means that you will have to pull strongly unCl the profile of the wing is deformed, when
this happens the required force will then significantly reduce. To maintain this manoeuvre you must
conCnue to hold the B Lines in the pulled down posiCon. The wing will then become deformed, horizontal
speed drops to 0 km/h and verCcal speed increases to –6 to –8 m/s depending on the condiCons and how
the manoeuvre has been performed.
To exit the manoeuvre, simultaneously release both risers, the wing will then slightly surge forward and
then automaCcally return to normal flight. It is be[er to let go of the lines quickly rather than slowly. This is
an easy manoeuvre but you must remember that the wing stops flying, it loses all horizontal movement
and its reacCons are very different compared to normal flight.
5.4 SPIRAL DIVE
This is a more effecCve way for rapidly losing height. You have to know that, the wing can gain a lot of
verCcal speed and rotaCon speed (G force). This can cause a loss of orientaCon and consciousness
(blackouts). These are the reasons why it is best to carry out this manoeuvre gradually so your capacity to
resist the G forces increases and you will learn to fully appreciate and understand the manoeuvre. Always
pracCce this manoeuvre when flying at high alCtude.
To start the manoeuvre, first lean your bodyweight and pull the brake line to the side to which you are
leaning. You can regulate the intensity of the turn by applying a li[le outside brake.
A paraglider flying at its maximum turn speed can reach –20 m/s, equivalent 70 km/h verCcal speed and
stabilize in a spiral dive from 15 m/s onwards.
