I. Answer the following questions in this discussion forum, along with any additional questions your instructor may post.

1. What is meant by the general expression ‘Turbines have a memory’? Also, describe ‘feathering’ when talking props.
2. Explain why a modern turbine engine is easier to analyze (from an accident investigation
   perspective) than a reciprocating engine.
3. What is meant by ‘critical flows’ needed by a turbine aircraft?
4. How do these questions and your answers relate to an investigation?

II. A substantial response shows thought and critical thinking, a short, two or three sentence response is not acceptable. Support your opinions with references. You may use course material, but be specific. Personal experiences etc. may be used to enhance your perspective of the questions but they must be valid and relative to the subject matter. Your instructor will evaluate your posts using the discussion rubric.
