CG Hook Location Computation
wrote:
When the aircraft manf has not done the research or made any
recommendations - how is the location for a CG hook computed?
One example - the SGS 2-33 installations I have seen (not factory) seem
to be far ahead of the actual CG.

I do hope that will help a little.
The location is dependent on the gliders total C of P location, but
primarily that of the wing airfoil. Also the height of the fuselage
determents the
relative position. Once the optimum location is calculated, a line is
drawn
from that point usually at or near the wing / airfoil to the bottom of
the fuselage
relative to the position the glider takes, when in full launch. A line
is then drawn
from the calculated point and the intersection at the bottom of the
fuselage.
A glider that has a tall cockpit, the hook appears much further
forward.
