a. Setting Up the AVA for a Particular Aircraft
The AVA requires aircraft-specific setup files in order to make the required measurements and analysis to
correct vibration and track problems. If the AVA is configured for the aircraft under test, the following SETUP
section is applicable. If the aircraft type does not appear on the Aircraft Type Menu, it will need to be created
and installed.
1. Selecting an Aircraft Type
The Aircraft Type Menu is selected by using the UP/DOWN arrow keys to move the inverse video cursor
over the Aircraft Type selection in the Main Menu, figure 1, and pressing the DO key. The Main Menu is
removed from the display and the Aircraft Types Menu appears, figure 1. Using the arrow keys, place the
inverse video cursor over the appropriate aircraft type and press the DO key to execute the selection.
The Main Menu will reappear with the Tail Number selection highlighted for selecting the next category in
the setup function. The QUIT key can be employed at any time to return to the Main Menu.
2. Selecting a Particular Aircraft Tail Number
The Tail Numbers Menu is selected by using the arrow keys to move the inverse video cursor over the
Tail Number selection in the Main Menu, figure 1, and pressing the DO key to execute the selection. The
Main Menu is removed from the display and the Tail Numbers Menu appears, see figure 1. Using the
arrow keys, place the inverse video cursor over the appropriate tail number and press the DO key to enter
the selection. The Main Menu will reappear with the Flight Plan selection highlighted for selecting the
next category in the setup function. The QUIT key can be employed at any time to return to the Main
Menu.
3. Selecting a New Tail Number
If the tail number of the aircraft under test is not in the list of tail numbers, a new tail number can be
entered by selecting NEW from the Tail Numbers Menu and pressing the DO key. An Entry Form will
appear, figure 1, allowing entry of the new tail number. A numeric tail number can be entered using the
numeric keypad. Entering an alphanumeric tail number can be done using the F1 and F2 function keys.
The F1 and F2 keys scroll through the allowed characters set. That set is the blank character, 0 through
9, A to Z, and a to z. F1 scrolls forward through the list and F2 scrolls backward. The RIGHT/LEFT arrow
keys move the cursor to the next character or previous character in the tail number. After the desired tail
number has been entered, press DO to store the new tail number and return to the Main Menu. The Main
Menu will reappear with the Flight Plan selection highlighted for selecting the next category in the setup
function. The QUIT key can be employed at any time to cancel the tail number entry and return to the
Main Menu.
4. Selecting a Flight Plan
A Flight Plan must be entered in order to identify the set of measurements to be taken. The Flight Plans
Menu is selected by placing the inverse video cursor over the Flight Plan selection in the Main Menu,
figure 1, using the arrow keys and pressing the DO key to execute the selection. The Main Menu is
removed from the display and the Flight Plans Menu appears, see figure 1. The Flight Plans Menu
contains the set of Test States pre-stored for the selected aircraft type. Test states are the flight
conditions at which measurements are taken.
For example: Flight Plans are categorized into Flight, Ground, Tail, or Power Spectrums. Within each
category are the Test States particular to the category selected. Select the desired Flight Plan by using
the arrow keys to move the inverse video cursor to the desired Flight Plan and press the DO key (a
various number of categories can be displayed, not necessarily all those listed here). When the DO key
is pressed, the selected Flight Plan is stored and the display returns to the Main Menu. The Main Menu
will reappear with the Flight ID selection highlighted for selecting the next category in the setup function.
The QUIT key can be employed at any time to cancel the Flight Plan entry and return to the Main Menu.
