GTX 335R, GTX 345R, GTX 33( ), or GTX 3000 Test
Operation of the GTX 335R, GTX 345R, GTX 33() or GTX 3000 Mode-S transponder is
accomplished using PFD 1, PFD 2 or the MFD. Refer to G1000 King Air 300 Series Cockpit
Reference Guide, listed in Table 1-1, for basic operation.
The integrated transponder/altitude reporting system must be verified in accordance with Title
14 of the Code of Federal Regulations (14 CFR) §§ 91.411 and 91.413, every 24 calendar
months, or any time the transponder is removed. This test requires the use of a Mode S ramp
generator. Specific instructions for operating the ramp tester are contained in the applicable
operator's manual. Refer to 14 CFR Part 43 Appendices E and F for testing criteria.
Note that for GTX 33D or GTX 3000 units, the aircraft must be put on jacks to simulate an in-air
condition in order to test the Mode S diversity transmission channel isolation.
If no other service is to be performed, continue to the return-to-service checks in Section 9.
