RAPID DESCENT TECHNIQUES
360° : In a 360° spiral, a sink rate of more than 15 m/s / 45 ft/s can be at-
tained. This manoeuvre can disorientate the pilot (loss of reference point
and strong acceleration).
One should learn this technique progressively. In particular one should
avoid the symmetrical mid braking position for coming out of the spiral.
This is best obtained by raising both hands progressively.
EARS: The DAYTONA has an important reflex profile bringing a high amount
of stiffness to the leading edge. That rigidity makes the DAYTONA very
stable but also the “Ears” configuration physically harder to implement.
Procedure: Trims closed, use the control loop straps, grasp the “A” riser at
link level and bring it down about 40 cm with a strong pull; maintain and
hold that position for the time of the maneuver.
“B-STALL” DESCENT : A “B-stall” descent” is a classic maneuver. Nevertheless
it must be used with discernment. The traction on the “B” risers must not
exceed 35 cm so as not to act also on the “A” risers at the same time. The
exit is generally spontaneous, and dynamic at times, all the more so if the
sink rate reached is high and the risers are let go quickly. If nevertheless, a
parachutal phase was to occur (wet or worn wing, and very slow riser re-
lease, for example), a slight turn using the toggles would likely help toward
a manageable exit.
For these 3 manoeuvres and for all other phases of flight, we strongly re-
commend keeping the toggles in the hands which enables an instant re-
turn to conventional piloting. The emergency manoeuvres should only be
used when necessary. After a while they weaken the lines, the ribs and the
attachment points.
Attention is drawn to the risk involved when spiralling with a lot of big ears
pulled on. This can increase the load considerably on the front lines to the
centre of the wing and weaken them prematurely :
therefore only use this technique when really necessary and have the integrity
of the entire structure including the lines subsequently tested in our work shop.
