Pressing DO will advance to the polar chart display and pressing QUIT will return to the Display Selection Menu. Once the polar display is visible, the vibration data is displayed by flight ID in both tabular and polar format. The data displayed on the polar display is highlighted in the table. Change the graphed data using the UP and DOWN arrow keys. This will change the points highlighted in the table and the points graphed Press QUIT to return to the Display Selection Menu.

Polar Trend Flights Display j. Using Bar Displays Bar displays are used to display selected vibration amplitudes. Bar displays are useful when a visual display of relative data is helpful to the user. An example of this would be absorber tuning. Absorber tuning typically requires the collection of multiple data points on different rotor RPMs. This data is usually collected at the same basic flight condition and time. A complete Flight bar display would be very helpful in this case. The following section describes the two different bar displays. 1. Complete Flight Bar Display. The Complete Flight bar display, figure 10, shows vibration amplitude data collected in a single Flight Plan. The display labels the Test State along the horizontal axis and the vibration amplitude along the vertical axis. The screen has the capability to display up to five Test States at one time. Use the LEFT and RIGHT arrow keys to move the screen left and right when more than five Test States are present on the bar graph F3 provides a tabular display of the graphed data to return to the Display Selection Menu press QUIT.
