Delays-Cancellations-Substitutions Rate Report

This report provides the delay, cancellation and substitution rates reported for a reliability fleet.

The count and rate of delays, cancellations and substitutions recorded against all aircraft in the reliability fleet is available for month of the report. Additionally, the report shows the running rate for three and 12 months preceding and including the month of the report.

The months for which information is depicted in the graph is based on the ‘Analysis Period’ attribute in the Set Options activity. For example, the March 2008 report with the ‘Analysis Period’ set to ‘12’ would show data beginning April, 2007 to March, 2008.

For in-depth information, see Delay rate computation, Cancellation rate computation and, Substitution rate computation.
