This FAA Advisory Circular (AC 36-1H) published in 2001 and updated in 2012 provides official noise level data for U.S.-certificated and foreign aircraft, including turbojet and propeller-driven planes tested under 14 CFR Part 36 and ICAO Annex 16 standards. Noise measurements, expressed in Effective Perceived Noise Levels (EPNdB), cover takeoff, sideline, and approach conditions and are organized across multiple appendices by aircraft type and compliance stage. The document serves as a reference for tracking progress in aircraft noise reduction and supports noise policy decisions at airports across the United States.Open full document
Notes
This FAA Advisory Circular (AC 36-1H, Change 1) provides noise level data for aircraft certificated under 14 CFR Part 36, including turbojet powered airplanes and propeller-driven small airplanes. It updates Appendix 1 and Appendix 8 with newly certificated aircraft noise levels, covering Stage 2 and Stage 3 compliance designations measured in Effective Perceived Noise Level (EPNdB). The circular also references noise data for foreign aircraft certificated to ICAO Annex 16 standards.
