Ground Noise Management Plan

Transcription

1 Xavier Oh, Noise Strategy Manager HCNF, 19 July 2017 Ground Noise Management Plan Overview

2 Ground Noise Management Plan - embedded in new Noise Action Plan ( ) Main Ground Noise Sources - Engine Ground Runs (EGR) / Engine Ground Noise - Taxiing, Hold and Single-Engine Taxiing - Auxiliary Power Units (APU) Runway/Air Noise Sources - Take-off Start of Roll (SOR) - Reverse Thrust on Potential Other Noise Sources - Airside Vehicles (e.g. Baggage carts) - Airstarts

8 Noise Measurements at raysbury Reservoir 5 Sept 1:30am EGR at T5

9 Engine Ground Runs (EGR) and Engine Ground Noise Proposed Actions - More robust OSI (Operation Safety Instructions) procedures with enhanced approval process (Airlines will have to justify more specifically the need for an EGR at night) - Enhanced data capture on EGRs for record-keeping, enable analysis and for reference - Matching engine ground noise events with AIP monitors - Adding noise monitors at the airport perimeter and in community areas - Detecting and locating engine ground noise events - Assessing community noise levels

10 Ground Noise Monitoring AIP and Perimeter locations

11 Taxiing, Hold and Auxiliary Power Unit Measurements July persons conducting live acoustic measurements for 3-5 days 6-10 unmanned noise logging monitors

12 Further Monitoring Plans Proof of concept testing - MEMS (Micro Electro-Mechanical systems) noise monitors to be deployed - Locations along runway side-line and around threshold positions - Long-term automated with digital uploading. - Spectral analysis to detect Reverse Thrust - Array analysis to assess Start of Roll noise levels and directionality - Coordination with AIP monitors to assess and triangulate EGR noise - Low cost MEMS/Raspberry Pie technology and / or deployment of HAL NMT (noise monitoring terminals)

13 LHR Ground Noise Model Update Noise Model - Current operations (2015) - Leq (16hr day) dba - Main noise sources - taxi, hold and Auxiliary Power Units (APU) - Air noise is not included Start of Roll, take-off,, reverse thrust.
