  • Develop Policies and Policy Statements on these items, associated with the design and operation of commercial air transport aeroplanes, as broadly defined by the contents of ICA0 Annexes 6 and 8, and associated ICAO documents, to be presented to the respective regulating bodies, authorities and operators, as well as to the interested public.
  • Liaise with aircraft manufacturers, system designers and engineers, as well as scientific and regulating bodies, to enhance their understanding of the view and requirements of the airline pilots to improve the safety and operational effectiveness of air transport aviation.
  • Develop proactive general statements and position papers for engineers, scientific and regulatory bodies, manufacturers and the general public on present and future developments to be made available for the public via the IFALPA media services.
  • Enhance the expertise of the members of the committee and their respective Member Associations by using contacts at scientific, engineering and manufacturing bodies.
  • Enhance the general standing of IFALPA, the airline pilots and their associations within the general public by the effort to improve air safety worldwide, as the stakeholder acting for the travelling public.
