2.2.2.2 AU Software Loading Procedure
The group of software programs that run on the AU is called the Application Program (AP), and
consists of the VXP Operational Program (OP), SmartCharts, balance models, data collection
routes, and other configuration files. Each time the VXP is used on a new aircraft type, an AP
specific to that aircraft must be loaded into the AU. Each AP has a unique name and part number.
Consult Chadwick-Helmuth for information on which AP is required for a specific aircraft.
The APs are provided on an 8M/16M CompactFlash Card, and must be loaded into the AU via the
CompactFlash Card Reader or the Zio! Reader in the PCMCIA slot. The APs may also be stored
on the hard disk drive of the DU for easier loading in the future. The AU is generally provided
with an AP installed. However, if a new or different AP is desired, it may be loaded into the AU as
follows:
1. Connect the system cables as detailed in section 2.2.1.
2. Apply power to the AU and DU.
3. Insert the VXP Application software 8M/16M CompactFlash card containing the
desired AP into the CompactFlash Card Reader.
4. Insert the 8M/16M CompactFlash Card and Reader into the PCMCIA slot on the
DU.
5. Start the DP by double clicking on (or touching twice in rapid succession) the VXP
icon
on the DU desktop. The dialog box shown in Figure 2-1 will appear.
6. Select Load Application from the start up menu (Figure 2-1) and click on the OK
button or press the Enter key.

7. In the “Look-in” pull down menu, select the (D:) drive (or appropriate location).
8. Select the desired AP file (*.app) and click on the Open button or hit the Enter key
to load the application.
NOTE:
To load an application using the Operating Program (OP), check the Override
Fast Upload check box before clicking the Open button. The upload may be
slower if this option is checked.
9. In the VXP about to load application dialog box, click on either Yes or No to save
the application to the DU hard drive. This will eliminate having to reload the
application from the PCMCIA CompactFlash Card Reader.
NOTE: Applications are saved in the directory C:\VXP\Apps.
10. Upon completion, the DU will connect to the AU and the Select Procedure window
will appear. See Chapter 3.
