CORRELATION OF FLIGHT PURPOSE CODES WITH FLIGHT MANEUVERS DATA FOR IMPROVED FATIGUE ESTIMATES IN SAFE PROGRAM

FATIGUE LIFE EXPENDITURE DETERMINATIONS UNDER THE SAFE PROGRAM DO NOT ACCOUNT FOR FLIGHT VARIATIONS FOR DIFFERENT MISSIONS, OR EMPLOY STATE-OF-THE-ART SEQUENCE-ACCOUNTABLE FATIGUE ANALYSES. THE PROPOSED PROGRAM WILL INVESTIGATE THE FEASIBILITY OF UTILIZING THE FLIGHT PURPOSE CODE DATA TO DEVELOP CORRELATIONS BETWEEN FLIGHT PURPOSE CODES, GROSS WEIGHTS, AND FLIGHT MANEUVERS SPECTRA; AND ESTABLISH ACTUAL LOADING HISTORIES. CORRELATIONS WILL BE ESTABLISHED UTILIZING ROUTINELY DOCUMENTED DATA FROM COUNTING ACCELEROMETER RECORDS, 3M FLIGHT RECORDS (YELLOW SHEET), AIRCRAFT/SQUADRON LOG BOOK RECORDS AND FROM FLEET FLIGHT LOAD SURVEY DATA. SUBSTANTIATION OF THE VALIDITY OF DERIVED CORRELATIONS WILL BE DEMONSTRATED FOR A SELECTED TACTICAL AIRCRAFT.
