Decisions relating to operational changes are often made on the basis of a wide range of strategic, economic, operational and impact-related information.
Often a compromise or balance is required to ensure that a disbenefit, or a combination of disbenefits, does not outweigh the value of the anticipated benefits. Thus when performing an environmental assessment and using the results to inform decision making, it is important to consider interdependencies or trade-offs of the proposed action and/or alternatives, to avoid, where possible, any unintended consequences. Definitions of interdependency and trade-offIt should be noted that, in the context of this website, the term “interdependency” is used to refer to a situation where a change in Factor A results in a change to Factor B (and vice versa), whereas the term “trade-off” is used to describe interdependency where an improvement in Factor A results in a detrimental change to Factor B.
Note: As the initial paragraph for each reference document was taken directly from the ICAO Publications Catalogue, it includes references to airlines, air carriers, aircraft operators, etc. These should be read as referring to all operators of aircraft, and not to any specific group.
The following pages contain a set of annotated bibliographies of ICAO documents that contain relevant information on interdependencies, and are laid out in the following standard format:
Please note that, whilst every effort has been made to ensure that all ICAO documents containing relevant information on interdependencies have been identified in this website, there may be some that have been inadvertently overlooked and those listed here should not be taken as an exhaustive list.
If additional information on interdependencies in an ICAO document, environmental or environmental plus non-environmental, is found then please contact ICAO at firstname.lastname@example.org giving details. That information will then be analysed and this website updated if appropriate. It is intended to update the list as, and when, required to ensure that further work within ICAO on interdependencies is captured in this site.
Note that the preservation of safety is, and will always remain, of paramount importance, and nothing in these documents shall take precedence over the requirement to maintain safe operation and control of aircraft at all times.
