CAP 737 Chapter 16 focuses on the critical role of effective communication in flight deck operations, highlighting its link to workload distribution and error reduction. The chapter emphasizes that quality and timing surpass the quantity of communication, detailing how messages can fail at various stages. It explores the challenges posed by language differences and stresses the importance of clear, standardized phraseology. Furthermore, the text examines the significance of sharing information and mental models within the crew and with ATC, alongside the necessity of assertiveness and verbal intervention when safety is at stake, even addressing potential social dynamics. The chapter concludes by suggesting methods for improving communication skills through training and aligning these skills with relevant pilot competencies.

CRM and TEM in Flight Crew Operations
This document introduces Crew Resource Management (CRM) and Threat and Error Management (TEM) in aviation, tracing the evolution of CRM from early, sometimes poorly received psychological or management-focused training to a broader scope incorporating concepts like situation awareness. The introduction of TEM in the 1990s provided a framework for proactively identifying and mitigating threats and managing errors, drawing on accident theory. It emphasizes that threats and errors are inevitable but must be effectively handled to prevent undesired aircraft states. The relationship between CRM and TEM is explored, highlighting how CRM behaviors act as countermeasures to errors at various levels, from avoidance to mitigation.

Understanding and Managing Flight Deck Workload
CAP 737 Chapter 6 focuses on workload in aviation, defining it as the mental effort required to process information and highlighting its complexity and links to other cognitive functions. The chapter explores factors that directly influence workload, such as task difficulty, multitasking, serial tasks, and time constraints, as well as indirect factors like fatigue. It examines the effects of high workload, including attentional narrowing, task shedding, reduced situation awareness, and increased error potential. The text provides practical advice for managing workload, emphasizing time management, crew resource management, and awareness of workload drivers. Finally, the chapter discusses the application of workload knowledge in training, both in the classroom and simulator, and its integral relationship with other aviation competencies.

Systems Thinking: Aviation Accidents, Complexity, and Cause
This paper distinguishes between two approaches to systems thinking in accident investigations: Systems Thinking 1.0 and Systems Thinking 2.0. The first approach, 1.0, focuses on identifying broken components, even those distantly related to the event, while the second, 2.0, considers the emergent properties and complex relationships within a system. Using the Alaska Airlines Flight 261 crash as a case study, the paper contrasts these perspectives. It argues that Systems Thinking 2.0, informed by complexity science, provides a more comprehensive understanding of accidents by acknowledging path-dependence, open systems, and the potential for small changes to have large effects. Ultimately, the piece advocates for a shift towards Systems Thinking 2.0 to improve aviation safety by addressing the normal social processes that can contribute to disaster.
