Operation of the GTX 33 Mode-S transponder is accomplished using PFD 1, PFD 2 or the MFD. Refer to
G1000 in King Air C90 Cockpit Reference Guide, listed in Table 1-2, for basic operation.

Code of Federal Regulations (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 Title 14 CFR Part 43
Appendix F for testing criteria.
If no other service is to be performed, continue to the return-to-service checks in Section 8.
