1. Install three platform scales under the two main gear and nose gear.
2. Shim or block up the aircraft so that the bubble level beneath the right side floorboard indicates
a level condition. (See “Cockpit Floor Board Removal” on page 3-46.)
3. Record the weight readings on the scales under the nose gear, main gear RH, and main gear LH.
4. Complete the Empty Weight and CG Calculation Form and perform the calculations to obtain the
total empty weight and CG position.

:
Fill out blank cells in table below.
Calculate the FS location of the CG by dividing the total moment by the total weight.
Total Wt (from above)=______ lbs
Aircraft CG Location, FS (Total M/Total Wt)=______ in
Verify that the above readings and calculations make sense by comparing them with the Pilot’s Oper-
ating Handbook records. Enter the new weight and balance information as a new baseline in the POH.
