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 units, the aircraft must be put on jacks to simulate an in-air condition in order to
