Calculating the Weight & Balance
Weight & Balance may be used during your pre-flight preparations
to verify the weight and balance conditions for your aircraft. By
entering the weight and arm values on this page, the GPSMAP 396
can calculate the total weight, moment, and center of gravity (CG) to
ensure a safe flight.
Before entering the various figures, you need to determine the
empty weight of the airplane and the arm (or “station”) for each
weight entered. These figures should be determined using the pilot’s
operating handbook for your airplane, which also notes the weight
limitations and fore/aft CG limits. Compare those figures to the
values calculated by the GPSMAP 396.
To perform weight and balance calculations:
1. Press
MENU
twice to open the Main Menu.
2. Highlight
Aircraft
from the vertical list of tabs.
3. Press the
ROCKER
right to highlight
Weight & Balance
.

.
8. Use the

9. Repeat steps 4 through 8 until all figures are entered. The
calculated moment, weight, and CG figures appear at the
bottom of the page. Keep in mind that the “Aircraft” (empty
weight/arm) figures must be entered as a reference to
calculate a valid moment, weight, and CG.
