REQUIREMENTS
NOTE
* Balance limits for control surfaces are expressed for "Approved Flight" configuration. "Approved
Flight" configuration
is that condition
of the control surface as
prepared for flight of the
airplane
whether it be painted or unpainted.
* "Approved Flight" limits must never be exceeded when the surface is in its final configuration
for flight.
DEFINITIONS:
UNDERBALANCE
is defined as the condition
that exists when surface
is trailing edge heavy
and is defined
by symbol (+). If the
balance beam sliding weight
must be on the leading
edge
side of the hinge line (to balance the control surface), the control surface is considered to
be underbalanced.
OVERBALANCE is defined as the condition that exists when surface is leading edge heavy
and is defined by symbol (-). If the balance beam sliding weight must be on the trailing
edge side of the hinge line (to balance the control surface), the control surface is considered
to be overbalanced.
