16. With the center zipper open, look inside the sail to preflight the following items:
a. The crossbar center section, including the crossbar hold down rope, the sweep wire hinge
bracket attachment to the crossbar, and the hinge bracket center hinge pin, push nut and
safety ring,
b. The routing and condition of the VG line and the attachment and alignment of the VG
triple blocks (pulleys).
c. Each crossbar half along it's entire length.
d. The top to bottom surface sail velcro attachments and internal ribs.
e. The main / backup hang loops. Verify that the main hang loop spreader bar is positioned
just below the bottom surface.
17. Check the operation of the VG throughout the range, and leave the VG set full tight. Zip up the
center sail zipper, and the lateral zippers at the rear end of the bottom surface in the root.
18. Install the nosecone as follows - fit the nose cone to the nose of the sail and stretch the top rear
end of the nose cone back along the center line of the glider. Press down to attach the velcro.
Then pull the bottom front end of the nose cone tight around the bottom of the nose and attach the
velcro. Finally, readjust the top rear attachment as necessary to remove any gaps between the
nosecone and the sail along the sides of the nosecone.
It is important to fit the nosecone carefully so that there are minimal discontinuities
in the sail in the nose area. Any discontinuity in the sail in the nose area, or along
the leading edge will tend to promote premature separation of the airflow, leading to
an increased stall speed and reduced performance.
19. Return the VG to the full loose position.
20. Install the bottom surface battens. The bottom surface battens are retained by a narrowing at the
front of the bottom surface batten pockets. You will feel increased resistance as you push the
battens into this area.
21. Conduct a complete preflight of the glider, checking all assemblies which have not already been
checked.
