This course will cover hover performance, transition to forward flight, downwind effects, anti-torque issues, rotor system characteristics (articulated, teetering, bearingless, hybrids), turboshaft engine characteristics, high speed forward flight characteristics, descent phenomenon (VRS, autorotation), dynamic rollover and ground resonance.
The course is taught by Jack Cress, a former helicopter pilot and aeronautical engineer. He has 40 years of experience teaching short courses on related topics.
The course would be beneficial to pilots, young engineers, prospective investigators and to experienced engineers interested in the interface of rotorcraft technology and common operational challenges.
Participants will receive a notebook and a CD of the course material.
Course fee: $350.00 USD

About the Lecturer: John P. (Jack) Cress
Mr. Cress was a career helicopter pilot in the U.S. Marine Corps (USMC), having flown nearly 4,000 hours during his near 25 years of military service. His non-flying duties included those of a NAVAIR Program Director, Depot Engineering and Quality Officer, and IMA Maintenance Officer. He also was twice assigned to the U.S. Navy’s Aviation Safety School, where he initiated the course in helicopter aerodynamics and also taught elemental structural failure analysis. He has taught related courses for the University of Southern California, the NTSB, and at various international venues. Mr. Cress earned a B.S. in Aeronautical Engineering from the Ohio State University in 1967, and completed course work for the M.S. in Aeronautical Engineering at the Naval Postgraduate School in 1979. He also earned the Program Manager credential from the US Defense Systems Management College in 1991. Following military service, Mr. Cress was employed as a product manager with Simula Safety Systems, where he was closely involved in the development of crashworthy, energy-absorbing seating systems for numerous rotary wing aircraft. Mr. Cress is currently the proprietor of Vortechs Helicopter Analytics, where he serves in investigational, instructional, and consultancy roles relating to various domestic and international operations. He maintains active memberships in the International Society of Air Safety Investigators (ISASI), the ASM International and AHS International.
