CVDR Operation
5.2.8
Fault Log To File
To perform this selection, a disk must be installed in the PI and the FDR cannot be record-
ing. If the FDR is recording, the PI will stop it. Selecting Fault Log To File on the Special
Functions Menu displays the Fault Log To File Menu. This menu is shown on sheet 2 of
Figure 5
When this menu is entered, the operator must enter the name of the file to which the fault
log is to be entered.
5.2.8.1
File Name Entry Field
There is a file name entry field (FILE ID) near the top of the menu. The rest of the menu is
taken up primarily by an array of selection characters. A cursor will appear over one of
them. the user can select characters by using the up, down, right, and left arrow keys to
move the cursor. When the user presses the select key, the chosen character will be cop-
ied to the FILE ID field. To remove character(s) from the FILE ID field, the up, down, right,
and left arrow keys are used to select each character and pressing the red DELETE key
removes the character from the field.
The FILE ID is
11
characters long. Only the first 8 characters are used in the filename it-
self. Also, characters in the FILE ID that are not legal DOS filename characters will be
changed to zeros. But the entire FILE ID will be copied into the file ID exactly as it ap-
pears on the menu. The file ID is a field in the file header that can be recovered when the
file is analyzed.
5.2.8.2
Fault Log File Names
Fault Log file names written to the disk as a result of dumping Fault Log data have the file
extension of .FLT. If the file name is the same as the name of a file that already exists on
the disk, the name chosen will be modified by replacing the last three characters of the
name with digits to make the user file name unique on the disk. This change will not be
visible when the user is doing the copy, but will become evident when the disk is taken to a
PC for analysis. This substitution of digits in the filename makes it impossible to overwrite
existing flight data on the disk.
5.2.8.3
START/CLEAR Tags
After the FILE ID is entered, the user should move the cursor (using the down arrow key
repeatedly) to highlight the START tag and then press SELECT to start dumping the Fault
Log to the disk location selected at the FILE ID entry field. After this function is accom-
plished, the PI screen automatically returns to the Main Menu.
Note also that from the START tag, the user can press the up arrow key to access the
CLEAR tag. If the user presses SELECT when the CLEAR tag is highlighted, the entire
FILE ID entry field will be blanked.
