National Aeronautics and Space Administration (NASA). This Draft 2 NASA Technical Handbook. April 2, 2012. 203 p. This Handbook provides guidance and recommendations for defining, developing, analyzing, evaluating, testing, and operating the FM element of flight systems. This Handbook provides a process for developing FM throughout the lifecycle of a mission. It also provides the fundamental concepts and terminology needed to understand the FM discipline; captures the typical pitfalls experienced on missions when FM is not appropriately addressed; provides exemplars for how to write FM requirements; supplies the basic building blocks of FM architectures; provides techniques for assessing and analyzing FM designs, gives insights into the unique needs of FM during the verification and validation (V&V) phase; addresses FM operational considerations; and delineates reviews and evaluation criteria to ensure that a flight system’s FM design is suitable for a mission, is staffed appropriately, and is progressing on schedule.
