Defect Due Date Formulas

15.9

This document details the formula change for Defect Due Date calculation in the TRAX app after version 15 service pack 9. The first section gives a breakdown of each formula (Pre/Post v15 SP 9) and the second half illustrates an example of the formula being calculated. 

Pre TRAX Service Pack 9 Formula

Before TRAX 15 SP 9, Defect Due Dates were calculated using the formula below:

(Scheduled Cycles) - (Actual Cycles since Defer Date) = Remaining Cycles / (AC Schedule Mean)

Post TRAX Service Pack 9 Formula

After TRAX 15 SP 9, Defect Due Dates are calculated using the formula below:

(Scheduled Cycles) - (Actual Cycles since Defer Date) = Remaining Cycles

Planning will then deduct time or cycles from future flights in the A/C Flight Schedule, and then forecast from the last scheduled arrival flight date if any remaining time is left over.

(Last Scheduled Arrival Flight Date) + ( {Remaining Cycles after further subtraction} / AC Schedule Mean) = Forecast Due Date

Note: If the remainder becomes 0 during the total subtraction, the Due Date will be the scheduled flight date from which the calculation was subtracted.
