Complete Flight Track/Lag Display i. Using Polar Displays There are two basic types of polar displays which display vibration amplitude and phase data.  The first type displays data collected during a single flight and provides a way of viewing all Test State data for a particular channel.  The second provides a trending capability allowing the viewing of amplitude and phase data collected at one Test State, but with different flight IDs. 1.    Complete Flight Polar Displays.  The Complete Flight polar display, figure 8, allows the viewing of a single channel's amplitude and phase data over every Test State in a selected Flight Plan.  When the Complete Flight polar display is selected from the Complete Flight display menu, an entry screen is displayed.  This entry screen allows the entry of the number of points to be displayed on the polar chart at a time.  As more points are selected, the display becomes more cluttered.  The default is four points at a time and up to eight points can be displayed at a time by placing the cursor on the "No of test:" line and entering the desired number on the numeric keypad.  Similarly the display of polar chart axes can be defeated by selecting the "Draw Axis " line and using the RIGHT or LEFT arrow key to toggle to NO.  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 Flight Plan vibration data is displayed in both tabular and polar format.  The data displayed on the polar display is highlighted in the table.  To change the graphed data, use the UP and DOWN arrow keys.  This will change the highlighted data in the table and the points graphed.  Press QUIT to return to the Display Selection Menu.
