5. Functional tests
When installed in accordance with these installation instructions, Stratus ESG complies with
14 CFR Part 91.227.
Final installation checks for Stratus ESG are the responsibility of the installer. The installer must
ensure that Stratus ESG is installed on an aircraft that coincides with the approval given within
the testing performed for the TSOs held by this device (TSO-C112e, TSO-C145d, and TSO-
C166b). Refer to Appendix A.
After installation is complete, verify operation as identified in 14 CFR Part 43, Appendix F. The
IFR6000 with OPT3 (manufactured by Cobham AvComm – formerly Aeroflex Test Solutions) or
equivalent test set can be used to determine compliance.
Additional testing requirements can be found in Chapter 4 of Advisory Circular (AC) 20-165B.
Additional functional tests may be required.
When installed correctly, Stratus ESG complies with 14 CFR Part 91.215 & 91.225. While in
airspace specified in 14 CFR Part 91.215, Stratus ESG must be maintained to 14 CFR Part
