INSTRUCTIONS FOR USING THIS WEIGHT AND BALANCE PROGRAM
(Print these instructions for use when setting up program for your aircraft)
If unable to enter data, 'Unprotect' sheets. "Tools>Protection>Unprotect"
ENTERING DATA FOR YOUR AIRCRAFT
from only the green and grey cells
in Columns A, B, C, & G on "Empty Weight" sheet.
1 Aircraft must be in LEVEL flight attitude for weighing.
2 You will need the CG Range of your airfoil, usually given as % of mean aerodynamic cord.
Convert these percentages for most foreward and most aft CG to a distance from your
data reference line.
3 If not given by manufacturer, establish a data reference line for weighing your aircraft.
Vertical Cowl line is a good reference, BUT measure from cowl line
to a point forward of spinner. Use this line to measure all 'stations'.
(by using a line in front of aircraft, all moments are positive, otherwise items
in front of reference line would be negative. Making all moments positive leaves
less room for error in the calculations.)
It should now be easy to measure all 'stations' from the cowl line, adding the
distance from cowl line to your imaginary reference line for all measurements.
REMEMBER and NOTE this measurement.
4 Weigh aircraft and enter weight and station on the top section of sheet.
(Weight on each wheel and the distance from reference line (Station).
This program assumes fuel and oil are empty. They can be removed without emptying
aircraft by using the 'Recalculation' part of the sheet.
If you wish to use an empty weight with normal oil quantity, then delete the 'oil' line on
the sheet or it will be duplicated.
5 Enter aircraft limits for your aircraft in grey cells on 'Empty Weight' sheet
6 Record the 'station' for aircraft loading in grey cells on 'Empty Weight' sheet.
7 For reference only, weight and station of items that could be removed, changed, or added
can be entered in the "List of removable equipment" at bottom of the 'empty Weight' sheet.
list such items as Starter, Alternator, Avionics equipment, etc.
Items listed here will not be used in Wt & Balance calculations until entered in the
"RECALCULATE FOR REMOVED/INSTALLED EQUIPMENT" box above the list.
8 WHEN FINISHED, PROTECT ALL SHEETS, AND MAKE 'READ ONLY'
Now only the green cells can be changed for calculation purposes.
All other cells are 'locked'.
Experiment on the "WT-CG LIMITS" sheet to see aircraft limit loadings
Use "preflight" sheet for checking various passenger, baggage, and fuel loads.
