7-41 – Main Rotor Track & Balance

Chapter 7

Revision 3.00, Apr 2020

angle is 30. Perform this for each adjustment point shown on the chart and the setup is
complete. The move line for the T AFT position will be 5:30. The move line for the
BLANK position will be 8:30. B AFT will have the move line at 11:30.

NOTE

Blade position names must be entered sequentially in either clockwise or counter clockwise

order. It does not matter what direction is chosen.

7.7.3.

– Tracking Influence Setup

The tracking influence setup screen is used to define the type and number of adjustment units
used to move a blade 1.0 unit of measure at the condition listed.

Conditions: The condition name will be automatically entered and is not editable.

Adjustment Name: Using the keypad, enter a three-character identifier for the adjustment type.

Example = PCL (Pitch Change Link), SWP (Sweep), WGT (Weight), and TAB
(Tab).

Unit: Using the keypad, enter a three-character identifier for the unit of adjustment type.

Example = FLT (Flat), PTS (Points), GMS (Grams), DEG (Degrees), and THO
(Thousandths)

Adjustments / in (mm): Enter the number of adjustment units to move the blade 1.0 unit of

measure. This will either be requested in Adj/in or Adj/mm depending on the
measurement units selected in the initial setup screen. In this example, it will take an
adjustment of 6 flats to move the blade tip one inch in ground or hover conditions.
