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
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 De-
lete 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. Characters in the file id that are not legal DOS file name characters 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.
3.4.6.4
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 CVRs file exten-
sion. Those units will have a .CVR for up to 35 minutes and then a .CRR for 35 minutes or
more.
3.4.6.5
Start/Clear Tags
After the File ID Is entered, the user should move the cursor (using the down arrow key re-
peatedly) 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.

STOP Playback from this menu provided the CVR is not in the Record Mode and has been
given an appropriate playback position (using FAST FORWARD Or REWIND ) When in the
Playback Menu). To toggle between STOP and PLAY, The user presses the SELECT key.
