The International Bureau of Aviation has expertise in the aviation industry and is capable of assessing aircraft and engines with regard to not only current standards of production and operational requirements, but also market value characteristics. Aircraft and engines are assessed through detailed reviews of their performance, avionics and navigation equipment, product technology and manufacturing procedures. IBA also takes into account the product operating costs, supplier base and user profiles. IBA is convinced that this product review is a valuable foundation for both product positioning and life-cycle management. Product review also helps to value the aircraft appropriately along the product life-cycle and shape future product developments.
