NOTE

Since some items of equipment are removed from the aircraft before installation of the agricultural equipment, reference to the weight and balance report should be made for correct basic weight and C.G. values.

CAUTION

To ensure that the gross weight of the aircraft does not exceed the gross weight permitted by local licencing authorities, restrict the fuel or cargo load as necessary.

MOMENTS OF POWDER IN HOPPER To determine moment of powder in hopper:

(1) Estimate to what level on the gauge glass the surface of the powder corresponds.

(2) From the above Spraying Fluid table find the moment arm which is given for this reading on the gauge glass.

(3) Multiply the number of pounds of powder in the hopper by this arm to obtain the moment.

Example of Use of Table

Suppose spraying fluid has specific gravity of .95

and there are 100 Imp. gal. of fluid in tank.

From the above table 100 Imp. gal. of water weigh

1000 lb and have a moment of -28100.

Thus 100 Imp. gal. of spraying fluid weigh .95 x

1000 = 950 lb and have a moment of .95 x -28100 -

-26695.
