Revision 2.2, Apr 2020

If you do NOT have existing trim balance weights installed press the [F5] “No” key to proceed
to the next step.

The solution screen displayed will depend on the selection made in 4.1.1.1.7 above. If the
“Holes:” field was set to “No,” the “Balance Solution” banner screen will be displayed as
described in paragraph 4.1.8.1 below. If the “Holes:” field was set to “Yes,” the “Prop
Suggested/Installed Weights” banner screen will be displayed as described in paragraph 4.1.8.3
below.

4.1.8.1.

– “Prop Suggested/Installed Weights” banner screen

The screen is identified at the top left as being “Run: 1 Eng 1”. Vibration amplitude and phase
angle are displayed for each channel being used (Channel A only in the example screen shown)
and a solution for the first run.
