Section 6
Wt and Bal/Equip List
6. Measurement of the reaction arms for a wheel weighing
is made using a steel measuring tape. Measurements
are taken with the airplane level on the scales, from the
reference (a plumb bob dropped from the center of either
main jack point) to the axle center line of the main gear
and then to the nose wheel axle center line. The main
wheel axle center line is best located by stretching a
string across from one main wheel to the other. All mea-
surements are to be taken with the tape level with the
hangar floor and parallel to the fuselage center line. The
locations of the wheel reactions will be approximately at
Fuselage Station 96.7 for main wheels and Fuselage
Station -10.3 for the nose wheel.
7. Jack point weighings are accomplished by placing
scales at the jack points specified in step 1 above. Since
the center of gravity of the airplane is forward of Fuse-
lage Station 83.1, the tail reaction of the airplane will be
in an up direction. This can be measured on regular
scales by placing ballast of approximately 200 pounds
on the scales to which the aft weighing point is attached
by cable of adjustable length. The up reaction will then
be total ballast weight minus the scale reading and is
entered in the weighing form as a negative quantity.
8. Weighing should always be made in an enclosed area
which is free from air currents. The scales used should
be properly calibrated and certified.
