1)

Rotate ident code selector knob.  Verify the most significant digit increas-
es from zero to seven with clockwise rotation and decreases with a 
counter-clockwise rotation.

2)

Repeat step 1) for the remaining three digits of the squawk code.

3)

Momentarily push the IDENT switch to store the selected code.  (The 
code will automatically be stored after a five second period if Ident switch 
is not momentarily pushed.)

(5) Conformity 

Inspection

Visually inspect the installed equipment to determine the use of acceptable work-
manship and engineering practices. Verify that all mechanical and electrical connec-
tions have been made properly.

(6) 

Ramp Test (see section 2.4.1.3, 2.4.1.4)

The following test will be conducted to verify operation.

1)

Aircraft Address and Maximum Airspeed Verification.

Verify that the correct Aircraft Address and Maximum Airspeed has been pro-
grammed correctly.

The Aircraft Address may be verified when the KT 73 is first powered on.  See 
Section 3.2.1 for details.

2)

Reply Frequency

Verify that the reply frequency is 1090 

±

 1 MHz.

2.4.1.3

Ramp Test (Per AC 20-131A)

This test requires the use of a Mode S Ramp Tester.  Specific instructions for operating the ramp 
tester are contained  in the applicable operator’s manual.  In systems with dual transponders and 
altitude sources configure the system to check each function.  Table 2-2 lists tests that will be per-
formed during ramp testing.  In addition, Table 2-2 contains a brief description of each test and the 
pass/fail criteria.
