Defining Stability Envelopes - CES, CAS, HCAS

Stability Engineering Institute 1 www.manhattanproject20.com 117-294-D Defining Stability Envelope CES vs CAS vs HCAS Adaptation, Operating Conditions and the Time Available to Intervene A stability envelope is meaningful only when we know what it protects, what conditions it assumes, and what controls can keep the system within it. The Stability Engineering Institute proposes that adaptation adds a continuing obligation: reassess whether the envelope remains valid as the system changes.
