Flight performance and planning
7.2.2.3 Calculating center of gravity – Cessna 172
An example of how Cessna has chosen to solve the task is shown below and on
the following pages.
You start by making a loading plan. The loading plan must include the weight of
the aircraft, crew, passengers, baggage and fuel.
The empty weight is stated in the aircraft's weighing report, the weight of the
pilot, passengers and baggage must be estimated, but make sure to get as close
to current values as possible, and if you are in doubt, you can ask the passengers
about their weight (if you dare ).
These weights are added, and the number is subtracted from the maximum
allowed flight weight. This number indicates the maximum weight of gasoline for
this flight (234 lbs).
Now we have the weight under control. Then we need the center of gravity.
For this, you need the weight and the moment. You find the moment by reading
the different weights in a moment chart (loadinggraph).
The moment for empty weight is stated in the aircraft's weighing report.
Once you have found the moment for all weights and entered them in the loading
plan, these are added (in the example here, 104.2 is obtained).
