The book "Flight Envelope Protection" provides a comprehensive analysis of the human-machine interface in aviation, particularly concerning the control systems of modern aircraft. It discusses the mechanisms that ensure pilots do not issue control commands that exceed the structural and aerodynamic limits of an aircraft. This technology is integrated into all modern commercial fly-by-wire aircraft and plays a crucial role in ensuring flight safety. The work highlights the advantages of these systems, especially in emergency situations where rapid responses are required without compromising the safety of the aircraft. The authors, Frederic P. Miller, John McBrewster, and Agnes F. Vandome, bring their expertise in engineering and IT to provide a well-rounded understanding of this important topic.
