Professional Education Course (PEC)
Instructor: Jack Cress

Price after Jan. 12: $635 Member | $925 Nonmember

This course introduces National Transportation Safety Board (NTSB) and International Civil Aviation Organization (ICAO) reporting requirements and discusses the history and primary categories of US and international helicopter accident causal factors. Using case studies, the course will focus on aerodynamically oriented causes, including hover performance, downwind effects, forward-flight transition, rotor-system characteristics, high-speed phenomena, descent issues (vortex ring state and autorotation), and ground issues (rollover and resonance). Turboshaft engine factors may also be addressed. A computer notebook and USB are provided.

Learning Objectives: By the conclusion of the course, participants will have learned:

  • Common causal factors involved in helicopter accidents and incidents
  • Performance considerations for helicopter rotor systems
  • Procedures and techniques for investigating helicopter accidents and incidents.
