  1. AIRCRAFT NOISEThe results of CAEP/5 by Gerard Bekebrede

  2. Committee on Aviation Environmental Protection (CAEP) • CAEP is a Committee of ICAO’s Council • CAEP/5 was the fifth meeting of CAEP and was held in Montreal from 8 to 17 January 2001. (The 4th meeting was held in 1998.) • During CAEP/5 the activities of CAEP in the period 1998 - 2000 were discussed • Recommendations were made to ICAO’s Council

  3. CAEP: Terms of Reference CAEP undertakes studies approved by the Council, related to control of aircraft noise and gaseous emissions. CAEP shall take into account: • certification schemes: technical feasibility, economic reasonableness and environmental benefit to be achieved; • developments in other associated fields, e.g. land use planning, noise abatement operating procedures, emission control through operational practices, etc.; and • progress in international and national programmes of research

  4. CAEP: Workprogramme Noise (1) • assessment of the prospects for further reduction of aeroplane noise levels • review of existing noise certification procedures with a view to adapting them to better representing the operational procedures used by modern aeroplanes • several activities related to noise certification (update manuals, simplifying procedures/reducing costs, procedures for tilt rotor aircraft, etc.)

  5. CAEP: Workprogramme Noise (2) • assessment of noise abatement procedures to reduce aircraft noise on the ground • collect information of aircraft noise monitoring around airports and update advisory documents on methodologies and applications of noise monitoring

  6. CAEP: 1998 - 2000 • Activities on noise were carried out in working groups: • WG1: Noise • WG2: Airports and Operations • FESG: Cost-benefit analyses • Steering Group meetings in 1999 and 2000 • Full CAEP meeting in January 2001

  7. CAEP/5: Results on aircraft noise • Recommendations of CAEP/5 included: • a new noise standard which is 10 decibels lower on a cumulative basis than the current Chapter 3 standards (for new aircraft design , effective 1 January 2006) • procedures for re-certification of existing aircraft meeting the new standard • more stringent noise standards for helicopters • additional/technical amendments of Annex 16

  8. CAEP/5: Results on aircraft noise (2) • proposal for new take-off noise abatement procedures • publication of guidance material on noise abatement procedures, land use planning and Noise and Flight Path Monitoring • Agreement that noise management should be considered in the context of a balanced programme consisting of: reduction of noise at the source, land use planning and control, noise abatement procedures and operating restrictions

  9. CAEP/5: Phase-out or operating restrictions • new noise standard is intended for certification purposes only • cost-benefit analyses do not support general phase-out of CH-3 aircraft in non-exempt regions • several members believed that regional phase-out is not supported by cost-benefit analyses

  10. CAEP/5: Results on aircraft noiseNext presentations session 3: • Working group 1 issues / -10 decibel stringence by Tom Connor • Importance of balanced approach by Elizabeth Andrade • Cost-benefit analyses by Upali Wickrama
