Correlating Training Effort and Tactical Proficiency
October 1, 2000
The purpose of this research memorandum is to attempt to correlate existing individual exercise training data that reflect warfighting proficiency to training effort expended. Our tasking was to use existing fleet data sources. Previous CNA studies have concentrated proficiency to training resources, but this effort required unique and extensive data collection and did not always reflect existing data sources. Our goal was to identify a similar connection based on existing fleet data sources. We analyzed unit training for three types of platforms for three mission areas: multi-crew support aircraft (P-3Cs) and their anti-submarine warfare (ASW) mission; surface combatants and their naval surface fire support (NSFS) mission; and tactical aircraft (F/A-18s) and their strike warfare (STW) mission.

CASS Requirements for a Regional Maintenance Center
July 1, 1996
The Consolidated Automated Support System (CASS) is a computerized Automatic Test Equipment (ATE) systems that is currently being fielded by the Department of the Navy. Over the next several years, CASS will replace existing ATE systems and help the Navy standardize test and training procedures. The Director of the Navy' s Air Warfare Division (N88) and the Support Equipment Program Office (PMA-260) asked CNA to review the Navy s current plans for CASS implementation within the fleet. These plans call for the phase integration of CASS into both Navy and Marine Corps maintenance facilities. This paper examines CASS requirements for supporting avionics components at shore-based Regional Maintenance Centers (RMCs). Specifically, our sponsor wanted to know: how many CASS stations do RMCs need; and how many of each type of CASS stations do they need? We address these questions by examining the planned RMC support for (only) F/A-18 and F-14 aircraft at Oceana.

Measures of Aircraft Reliability, Maintainability, and Safety: Do They Measure 'System Quality'?
June 1, 1987
Principal components analysis is applied to nine indicators of aircraft reliability, maintainability, and safety. The indicators are standard readiness measures such as mean time between failure at different points in the aircraft's career. The data are adjusted to include only the airframe. The assumption behind the analysis is that the observable variables are indicators of an underlying unobservable variable, 'airframe quality.' This principal components analysis provides a quality 'score' for each aircraft. Five of the six aircraft analyzed fall within one standard deviation of the average score. The scores for the first principal component account for over 85 percent of the variation in the original indicators, which is highly significant in a statistical sense. This finding supports the initial hypothesis; 'quality' exists and is the major source of variation across aircraft in the nine indicators.
