8-19 – Tail Rotor Balance Chapter 8 Revision 3.00, April 2020

Pressing the [F2] “None” key will delete all “Installed” entries. This function is used
when an adjustment is to be skipped on the current run.

Pressing the [F3] “Re-Solve” key will allow you to find an alternate solution. This
may be used when weight is already attached to the tail rotor or the suggested weights
are smaller than the minimum hole weight. See below for instructions on using the
“Re-Solve” feature.

Pressing the [F5] “Quit Job” key will exit the current job and store it as complete.
Warning
Using the [F5] “Quit Job” function will close the job and not allow you the resume option at a
later time. If you wish to pause the job temporarily, press the “Main Menu” key or simply turn
the analyzer off. You may then use the “Resume” function to complete the job.
When you have finished entering the adjustments performed, press [OK] to continue to the
next run.
8.3.12. – Tail Rotor Re-Solve Feature
The [F3] “Re-Solve” key will allow you to find an alternate solution. This may be used when
weight is already attached to the tail rotor or the suggested weights are smaller than the
minimum hole weight. For instance, in the example below, the attaching nut and bolt weigh
3.9 grams. This is larger than either of the suggested weights. In this case, press the [F3] “Re-
Solve” key and follow the instructions below.
Using the keypad, record the actual weight(s) installed between runs and their location. If
you choose to remove weight from an opposite or alternate position, enter the negative
adjustment. Do this by moving the highlight to the appropriate field, press the [SPACE -] key
to produce a (-).
Using the screen below as an example, the suggested weight installation is to add 2.5 Grams
to the #6 weight hole location and to add 2.8 Grams to the #7 weight hole location. This is
shown on the top line of the screen, directly below “Run 1 Suggestion:”
In the example below, the closest matching weight combination was to add 2.5 Grams to the
#6 weight hole location and to add 3.0 Grams to the #7 weight hole location. This change
was made on the tail rotor and entered into the analyzer adjacent to the appropriate weight
hole locations under the “Enter Installed Wts” portion of the screen. This adjustment will
only be possible if there is already attaching hardware in holes # 6 and #7. If this is not the
case continue below.
