you are setting up this template on a computer, as a test plug in
the above sample numbers to make sure that your cell formulas
agree. Then go ahead and input your numbers for your Velocity.
Now, let’s run through the worksheet using the numbers from
the previous sample. Multiply each “Weight” by the correspond-
ing “ARM”, and enter the total in the column to the far right.
Next, add the total weights and enter it on the bottom row
“Total” under the ‘Weight” column (2579 lbs). Now add the total
Moment and enter it on the bottom row “Total” under the
“Moment” column (338058 inch lbs). Last step is to divide the
total moment by the total weight to arrive at the CG (131.08”).
The blank worksheet (OM-WB) is there for you to use as a
template for manual calculation. Make extra copies first. Enter all
the known data first. Start with column E “ARM aft” and enter
each ARM that you previously calculated for your aircraft. Next
enter the Basic empty weight on Column D Row 5. Next enter
the maximum gross weight on column D row 16 (2250 for stan-
dard). Once all the known information is entered, make some
extra photocopies. Know go ahead and figure in some weight and
balance examples for your aircraft, just like we did in the previous
sample.
You must complete weight and balance data and have it in
your aircraft in order to pass an “FAA ramp check”! Remember
the word “ARROW” as a reminder of what you need to keep in
your aircraft. A= Airworthiness Certificate (along with Statement
of Operating Limitations), R = Registration Certificate, R = Radio
Station License, O = Operating Limitations,W = Weight & Balance
data.
We recommend calculating a number of extreme w&b exam-
ples to leave as part of this Owners Flight Manual. Calculate many
samples with low v. high fuel, fore v. aft CG limits, etc.
