4-23 – Propeller Balance Chapter 4 Revision 2.2, Apr 2020
4.1.5. – Start Aircraft
Prior to performing any dynamic balancing, it is advised to follow the instructions in the ACES
Systems’ Guide to Propeller Balancing included with your analyzer for inspections prior to
balancing. The document is FAA approved and provides guidelines for the selection and
installation of balance weights.
When you have completed the inspections, and physical equipment setup tasks, press [OK] on
the analyzer to continue with the propeller balance job.
The analyzer will then display the “Start Aircraft” banner screen (shown above), with the
statement to: “Perform a FOD check and start engine(s) per flight manual.” Start the engines and
establish normal operating conditions. When normal operating conditions are established, press
[OK] to continue.
4.1.6. – Acquiring Data
The “Set Engine Speed” banner screen is displayed. At the top left of the screen, the run number
and engine number, if balancing two engines, is displayed. The center of the screen displays the
following information;
“Desired RPM:” - The balance speed entered in the setup being used. This is your target
RPM for balancing.
“Current RPM: - Indicates the current propeller RPM. Attempt to match the Desired
RPM with the Current RPM as closely as possible with throttle/prop lever adjustments.
“Difference:” - The difference between the Desired and the Current RPM.
