Reports & Testimonies

  • GAO’s recommendations database contains report recommendations that still need to be addressed.

    GAO’s recommendations help congressional and agency leaders prepare for appropriations and oversight activities, as well as help improve government operations. Recommendations remain open until they are designated as Closed-implemented or Closed-not implemented. You can explore open recommendations by searching or browsing.

    GAO's priority recommendations are those that we believe warrant priority attention. We sent letters to the heads of key departments and agencies, urging them to continue focusing on these issues. These recommendations are labeled as such. You can find priority recommendations by searching or browsing our open recommendations below, or through our mobile app.

    Recommendation: To help FAA better manage and understand the uncertainties of its forecasts, the Secretary of Transportation should direct the FAA to apply risk-management practices to analyze and report on uncertainty. Specifically, the FAA should, for both the Aerospace and TAF forecasts, analyze and report the forecast's uncertainty, establish forecast error thresholds, and develop an approach that will prompt forecast review when error thresholds are exceeded, and, for TAF forecasts, monitor and publish multi-year historical error performance, as FAA does for the Aerospace Forecast.
