CVDR Operation
5.3.6.2
Copy Menu Entry (Copy)
When the operator selects COPY on the CVR File Control Menu, A File ID Selection Menu
Is displayed on the PI screen. The user cannot enter this menu unless a disk drive is in
place at the PCMCIA slot in the bottom of the PI.
Attempting to do otherwise will result in the message, “
No Disk Present”
. The user se-
lects a new file ID for the file selected to be copied to the disk. Instructions for selecting
the new file ID are provided in the next paragraph. The User then moves the cursor to the
START tag and presses SELECT. The file is then copied to the disk.
5.3.6.2.1 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 charac-
ter will be copied 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 by
pressing the Red Delete key, removes the character from the field.
The File ID field is
11
characters long. Only (up through) the first 8 characters are used in
the file name itself. Also, Characters in the file id that are not legal DOS file name charac-
ters will be changed to zeros. But the entire file id will be copied into the file id exactly as it
appears on the menu. The File ID is a field in the file header that can be recovered when
the file is analyzed.
5.3.6.2.2 Disk File Names
All file names written to the disk as a result of copying CVR data have the file extension of
.CVR added automatically by the PI. If the file name chosen is the same as the name of a
file that already exists on the disk, the name will be modified automatically by replacing the
last three characters 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 file name makes it
impossible to overwrite existing flight data on the disk. The exception will be those NAND
memory CVDRs file extension. Those units will have a .CVR for up to 35 minutes and then
a .CRR for 35 minutes or more.
5.3.6.2.3 Start/Clear Tags
After the File ID Is entered, the user should move the cursor (using the down arrow key
repeatedly) to the start tag and then press select to advance to the CVR Copy 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.
5.3.7

and STOP Playback from this menu provided the CVR is not in the Record Mode and has
