It isn't necessary to dissipate the static charge to actual ground.  The
important thing is to neutralize the potential between the fuel source and
the aircraft.  Probably one of the best areas to do this is the strut of a
gear or the exhaust of the engine.  The main problem on composite aircraft
would be to dissipate the potential between the airframe skin and the metal
parts of the airframe.  If the composite material does not build up a
potential between the fiberglass body and the metal aircraft parts, then
grounding the plane the conventional way is fine.  If there is no

flow between the fiberglass and the metal parts, then there is a problem.

I would think that conventional grounding techniques would work fine. (a
guess)  If there is evidence of a large potential between the fiberglass

the metal parts, then there could be a problem.  The most important thing

do would be to connect the gas caps to the aircraft ground through some

of connection thereby eliminating the chance of static charge right where
the fuel is to be applied.

While checking out in a Fuga Jet, I noticed that the nose gear had a piece

of

"wound" wire (looks like a mixture cable cover) that was attached to one

side of

the nose gear., protruding down and actually rubbing the ground (it is
adjustable). A convenient and simple way of dissipating the static
