Airplane weighing procedure
Procedure:
1.) Prepare aircraft by off-loading any luggage and loose items which
are not part of the standard equipment
2.) Check coolant and oil filled, replenish if needed
3.) Drain fuel
4.) Level airplane on scales (reference upper rivet row below canopy
frame)
5.) Determine individual weight on all three gears (W_N, W_L, W_R)
6.) Check gear lever arms (X_N, X_L, X_R; reference propeller flange
X=0.0m, or firewall X=0.960m).
7.) Calculate Empty Weight:
W_empty = W_N+W_L+W_R
8.) Calculate Empty airplane moment:
M_empty = WN*X_N + W_L*X_L + W_R*X_R
9.) Calculate Empty Airplane CG:
CG_empty = M_empty/W_empty
10.) Record date, empty weight, moment and CG in the weight and
balance record sheet (next page).
