Title:
FAULT MANAGEMENT SYSTEM FOR GAS TURBINE ENGINES
Document Type and Number:
WIPO Patent Application WO2003042928
Kind Code:
A3
Abstract:
Disclosed herein is a "real time" Time Limited Dispatch (TLD) fault management system and method for evaluating the operational suitability of an engine's electronic control system. The TLD system disclosed herein uses a software algorithm to compute or predict the probability of mission success for a given upcoming mission length (e. g., two hours) and the time remaining to repair control system faults before dispatch is disallowed or the flight suspended, regardless of the probability of success.
