NOISE CHARACTERISTICS The table below shows the certificated noise level for various configurations of the Liberty XL-2 airplane. Propeller Dawley Exhaust Type and Part Number Gross Weight (lbs) FAR 36 Appendix G Amendment Noise Level (db) A Weighted MT MT Standard DEL 200201-002 Quiet DEL 200201-003 1653 27 75.8 1653 27 74.0 Table 1 Noise Figures The baffle P/N DEL 200201-508 inside the muffler tailpipe and the two oblong openings in the pipe can identify the reduced sound Dawley Exhaust, P/N DEL 200201-003. If there is no baffle and no oblong openings in pipe, then the exhaust system is the Dawley Exhaust, P/N DEL 200201-002. Figure 5-1 No determination has been made by the Federal Aviation Administration that the noise levels of this airplane are or should be acceptable or unacceptable for operation at, into, or out of, any airport.
