Book Description
This report documents the results of a five-year research programme commissioned by the Civil Aviation Authority (CAA) to demonstrate the intelligent analysis of helicopter Health and Usage Monitoring System (HUMS) Vibration Health Monitoring (VHM) data. The goal of the programme was to improve the fault detection performance of HUMS. A HUMS Advanced Anomaly Detection (AAD) capability, and a system to implement it, was developed in Phase 1 of the research programme. In Phase 2 of the programme, the AAD system was subjected to a six-month in-service trial, refined and then re-trialled. The new HUMS AAD capability that has been developed is based on density estimation, and incorporates a number of novel features to ensure that the technique is robust, and addresses all the practical issues related to working with in-service HUMS VHM data. The two trial periods confirmed that AAD represents a significant advance in HUMS data analysis, resulting in improved fault detection performance, a reduced 'false alert' rate and increased system effectiveness. The greatest scope for further improvement in the combined performance of the AAD system and its use by maintenance engineers is through the development of a second level of advanced data analysis, based on data mining and automated reasoning technologies.

Book Description
The rotorcraft industry is developing a number of techniques, methodologies, and associated equipment for monitoring health and usage of critical rotorcraft flight components. Industry is planning to incorporate this technology on a number of new aircraft. The Federal Aviation Administration (FAA) has the responsibility for certification of these aircraft and the equipment they contain. This effort is concerned with the health and usage equipment. To best accomplish the certification of these equipment, the FAA expects to develop detailed certification criteria addressing specific issues of concern. In the near-term, the FAA objective is to develop a better understanding of what is being developed by industry (with emphasis on United States industry), what firms are involved, who are the key people involved, what parts of this technology are mature to the point that some airworthiness credit may be appropriate, and what parts of this technology are not yet mature. With information such as this, the issues that need to be address via certification criteria can be determined quickly. This effort is principally intended to provide support in reaching the FAA's near-term objectives. This report describes the results of an extensive literature search of health and usage monitoring technology. Over 1,000 abstracts were reviewed and analyzed. The report contains a description of 20 systems and abstract of 90 papers pertinent to health and usage monitoring.

Book Description
This report presents a description of a computerized airborne data acquisition system used to measure pilot performance in a UH-1 helicopter. The unit can record approximately 20 aircraft parameters in addition to other experimental data. This report can also serve as an operator's manual for the system.
