PILOT-INDUCED OSCILLATIONS (PIO) are rare, unexpected, and unintended excursions in aircraft attitude and flight path caused by anomalous interactions between the aircraft and pilot. They have occurred at some time in the development cycle for just about every new air vehicle design. Catastrophic events that lead to mishaps cost time, money, and sometimes lives. With the advent of modern flight control systems, the potential for catastrophic PIO is on the rise.
In this two-day short course, the phenomenon of PIO will be examined from its origins to today's events. With practical examples from flight research, flight test, and operational experience, the speakers identify the myriad causes of PIO and describe the cures available to the design engineer.
The course is intended for a broad audience including program managers, controls and flight test engineers, and pilots. At the end of the course, the attendee will be familiar with:
- Causes of the most publicized PIOs
- Methods for their prevention by design and prediction by analysis
- Simulation and flight test techniques to expose PIO tendencies
- Tools for real-time monitoring

ABOUT THE SPEAKERS:
DAVID G. MITCHELL is Technical Director for Hoh Aeronautics, Inc., in Lomita, CA. In his 27 years in aerospace, he has co-authored 50 technical papers and more than 50 technical reports, and has contributed articles to two textbooks. A report on PIO for the U.S. Air Force in 2000 is used as a reference source by military and civilian agencies, and is considered a "must read" on the topic by engineers at the Federal Aviation Administration.

DAVID H. KLYDE is a Principal Research Engineer for Systems Technology, Inc., in Hawthorne, CA. In his more than 18 years of experience, he has worked on projects involving handling of both air and ground vehicles. He was the project engineer for STI on the USAF Unified PIO Theory program that investigated the role of actuator rate limiting as a causal factor in PIO. He was also project engineer on a recent program to identify the causes of, and develop cures for, PIO during landing rollout on the Navy's current jet trainer.
