Big ears
Big ears are the simplest method for rapid descent. The advantage is that the horizontal
speed is higher than the sink rate (3-5 m/s), unlike a spiral dive or a B-line stall. This rapid
descent technique is used to quickly and horizontally exit a dangerous area in the desired
direction. It is even possible to land using big ears (for example top-landing).
In order to collapse the outermost part of the wing, pull the A1-risers down. The Pasha 7
easily tucks the wingtips and enters a stable descent mode. The pilot keeps hold of the
brake handles along with the A1-risers in his hands. By braking on one side and weight-
shifting, the canopy remains steerable. In order to increase the sink rate as well as the
horizontal speed, this manoeuvre should be done together with using of the trim system.
Release the trim system after big ears are induced. Big ears substantially reduce the risk of
canopy stability problems in turbulent air. To exit big ears release the A1-risers. The
canopy does slowly self-recover. To quicken the recovery, the pilot can dynamically pull
down and immediately release the brakes of the glider.
WARNING! Never do big ears in spirals, as this may drastically reduce the number of
lines taking the already high loads, causing structural failure.
Pasha 7 has the cleat on the D-riser which makes it possible to fix the outer A-lines so they
can be held in for an extended period. With big ears applied, the Pasha 7 can be steered
using the brakes. Before using the cleats it is necessary to uncover the neoprene safety
covers by pulling the red webbing on it up. After the big ears manoeuvre, put the neoprene
cover down to avoid catching any lines.
NOTICE: The outside A-line is divided in two pieces (A0 and A1) due to fast and easy
repair if the cover of A0 line is damaged. Line A0 is Liros TSL500, length after sewing is
70,0cm (valid for all sizes of Pasha 7).
