TEM stands for which concept in aviation safety?

• A. Time and Efficiency Management
• B. Threat and Error Management
• C. Tool and Equipment Monitoring
• D. Training and Evaluation Methods

Answer: (B)

Threat and Error Management is the concept tested. In aviation safety, TEM is a proactive framework that helps crews recognize and handle threats—external pressures and task loads that can raise workload or degrade performance—and errors, which are unintentional actions or omissions that deviate from intended procedures. The goal is to anticipate threats, monitor for errors, detect and trap them before they lead to an unsafe outcome, and recover quickly when a deviation occurs. TEM focuses on how people, procedures, and automation interact within the flight system, promoting system-wide safety improvements rather than blaming individuals. It relies on crew resource management, standard operating procedures, checklists, and good workload management to reduce risk. The other ideas—time and efficiency management, tool and equipment monitoring, and training and evaluation methods—are important in aviation but do not capture this integrated safety framework.
