System identification methods are ideally suited for rapidly determining bare-airframe simulation models of fixed-wing and rotorcraft UAVs, since UAV configurations change widely throughout their development process. Also the parameters needed for a physics-based model are often poorly known for UAVs, or the modeling assumptions do to correspond well to the physical characteristics of modern UAV configurations. A full-flight envelope UAV simulation can be obtained from “stitching” together only a few point identification models, obtained from a very limited flight-testing program. This webinar will review the fundamentals of the frequency-response method for UAV aircraft and rotorcraft system identification. Special methods are needed for modern multi-copter or eVTOL configurations with highly redundant controls. Identifications methods and results are illustrated with many recent UAV examples. Particular emphasis is given to the important role of system identification in UAV flight control development, implementation verification, and documentation of performance. The course will review key methods, computational tools, and complimentary reference material. The lecture material will be followed by a question and answer period.

If you Google for "aircraft cylinder break-in" you'll get about 488,000 hits. Each manufacturer (Continental & Lycoming) has a Service Bulletin about it, most PMA cylinder makers (ECi, Superior) have a procedure, and many of the custom overhaul chops (Pann Yann, Victor, RAM) have one. Some of the type clubs have one - even Shell Oil offers advice. That's a lot of reading - it's probably smarter to just read watch Mike Busch's webinar.

Airport operations generally contribute to local and regional air quality. However, there are uncertainties in quantifying emissions, especially from aircraft. This webinar described what is currently known about the potential impacts of airport activities on local and regional air quality and public health. The presenters also introduced an airport air quality management electronic resource library and guidebook.
