For 0 thru 9, press the appropriate digit to enter a new code. When the first digit
of a new code is pressed, the digit display field is cleared, the display shows that
digit in the left−most digit field with the other digits blanked and the FID indicator
will flash. CLR can be pressed while in the process of entering digits to clear the
digit field and allow entry of a new code. Pressing CLR again will result in the
display of the previously active code. Upon completing entry of the FID cod,
pressing ENT results in transmission of the new FID in about five (5) seconds. If
the ATC mode is selected before pressing ENT, the partial entry is retained in
memory and the FID indicator continues to flash. Upon returning to the FID
mode, the new FID code entry process can be completed. The FID indicator will
stop lashing when ENT is pressed.
For letters A−Z, repeatedly press the appropriate key until the desired letter
appears in the display. The first press of any key will cause the digit to appear in
the display. The second press of the same key within 2 seconds will cause the
digit to change to the first letter on that key. The third press of the same key
within 2 seconds will cause the letter to change to the second letter on that key.
The next press within 2 seconds will cause the letter to change to the third letter
on the key pad (if applicable). The next press within 2 seconds will cause the
letter to change back to the digit on the key. Waiting 2 seconds between key
presses, or pressing another key at any time, will advance the cursor to the next
character space or will cause the digit of the key pressed to appear in the next
location on the display. Flight ID can be between 1 and 8 characters in length.
E. VSI/TRA Display
The VSI/TRA display, Figure 1−12, is used to display current vertical speed and TCAS
traffic/warning information. The display consists of a full color, active matrix, liquid crystal
display panel. The display quality compares favorably to CRT displays but requires less
power, weight, and volume than a CRT with a similar display area. Table 1−9 gives items
and specifications particular to the unit. Figure 1−13 contains an interface block diagram
of the 41−pin version VSI/TRA and Figure 1−14 contains an interface block diagram of
the 55−pin (bootstrap) version of the VSI/TRA.
