4.3 Configuration Items

4.3.1 Aircraft Registration/VFR Flight ID

The default flight ID for an aircraft not on an IFR flight plan should be the
aircraft registration. Enter the aircraft registration using the numeric buttons
and the ENT button. To aid character entry, the lower portion of the display
shows the alpha numeric characters selected through multiple presses of the
numeric buttons. When the correct character is shown in the flight ID section
of the screen, press the ENT button to accept and advance to the next digit.
Note that the aircraft registration is loaded as letters and numbers only.
There are no dashes or other punctuation marks, and no spaces can be
inserted. When you enter a terminator character it finishes the data entry and
moves to the next item.

4.3.2 Aircraft Address Programming

The Mode S address is a 24-bit number issued to the aircraft by the
registration authority for the aircraft. These addresses are usually written as
a six-digit hexadecimal number, although you may also encounter one
written as an eight-digit octal number. The KT 74 only understands the
hexadecimal format, so you must first convert an octal number to
hexadecimal.
Enter the six-digit aircraft address using the numeric buttons and the ENT
button.
Press FUNC to move to the next menu item.
In the case of an N registration aircraft, this Mode S address will normally be
filled in automatically based on the tail number.

4.3.3 VFR Squawk Code

When the pilot presses the VFR button, a pre-programmed code will replace
the current squawk code. The code is set up next; the choice of code will
depend on the normal location of the aircraft. In the U.S.A., the VFR squawk
code is 1,200. In most parts of Europe, the VFR squawk code should be set
to 7000.
Enter the four-digit squawk code using the numeric buttons.
Press FUNC to move to the next menu item.

4.3.4 Airspeed Category

Mode S transponders can transmit their maximum airspeed characteristics to
aircraft equipped with TCAS. This information is used to help identify threats
and to plan avoidance actions by the TCAS equipped aircraft. The airspeeds
are grouped in ranges; using the numeric buttons (6 and 7), select the range
that corresponds to the aircraft. Press FUNC to accept and move to the next
menu item.
