  • The user is expected to present the AER material in a manner consistent with its original meaning and intent. Sincere effort should be made to present the material in a way that does not distort the findings or give a false impression.
  • Non-alteration of the AER findings.
    • The research findings cannot be altered; they must be used “as is.”
    • The numerical values on graphs cannot be changed.
    • For example, if a graph indicates aviation’s effectiveness was 2.67 out of 4.0, the value 2.67 cannot be changed.
    • The wording of Axioms & Principles (A&Ps) cannot be changed.
    • The wording of the Ways cannot be changed.
      • For example, if a Ways Table contains the Way “It saves travel time,” that Way must be presented as “It saves travel time.”
    • Respondent statements.
      • The wording of Respondent Statements cannot be changed.
      • Although the researcher attempted to capture the statements verbatim, this was not always achieved. Therefore, the Respondent Statements cannot be portrayed as direct quotes (i.e. with the use of quotation marks).
  • Formatting and colors.
    • The format (i.e. the arrangement of the elements) of the material (e.g. the graphs or tables) may be changed to facilitate utilization.
    • All re-formatted graphs and tables must contain all of the same elements (e.g. title, sub-titles, scale, values, labels) as the original material.
    • The AER materials were designed using a color system to help the user recognize different categories of findings (e.g. green is used for Facilitation of Work; black is used for Trip Detriment). If it’s possible and practical to do so, the AER color system should be used. However, colors may be changed if necessary.
