Committee on Aviation Environmental Protection
(CAEP)

• CAEP is a Committee of ICAOs 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 ICAOs Council

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

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
