5-2 EMPTY WEIGHT CG CALCULATION

5-2.1 D

ETERMINE THE

TATIONS OF THE

ANDING

EAR

The empty weight CG of the airplane must be determined before any

additional CG calculations can be made. The first step in determining

the empty weight CG is to measure the distances from the datum to the

landing gear. These distances will vary slightly among Sportsmans.
First, with the airplane supported with the wings and the waterline level,

use a plumb bob to mark the location of the cowling mounting flange

joggle (the cowling/fuselage split line) on the floor.

NOTE:

To level and weigh the taildragger Sportsman, prop the

tailwheel on a

stable support

of some kind and block it up to the

appropriate height. Use the permanent waterline marks the fuselage.

Measure forward 58" from the cowling joggle mark and mark a line on

the floor at this point perpendicular to the longitudinal centerline of the

airplane. This line represents the intersection of a plane in space with

the floor. This plane is defined as the reference datum (Station 0.00)

from which all moment arms are measured.
Measure and record the horizontal distances “X” and “Y” from the

datum to the centers of the main and tailwheel axles respectively. See

Figure 5-1. These distances represent the stations of the landing gear.
