A typical TEM example in flight is:

• A. Pilot fatigue leading to delayed checklist completion
• B. Improper fuel planning causing fuel imbalance
• C. Miscommunication leading to altitude or heading deviation
• D. Incorrect altimeter setting causing altitude error during descent

Answer: (C)

In TEM, we examine how threats and human factors can lead to errors that put the aircraft in an undesired state and how crews detect and mitigate those situations. A typical TEM example is miscommunication that leads to altitude or heading deviation. When communication isn’t clear—between pilots or with ATC—the crew can misinterpret instructions or lose situational awareness. That misinterpretation is an error, and without proper checks, it can result in the aircraft being off its assigned altitude or heading. The defense against this is strong CRM and standard procedures: clear phraseology, readbacks, confirmation, cross-checking between pilots, and using instruments to verify altitude and heading. While fatigue delaying a checklist, improper fuel planning, or an incorrect altimeter setting are real issues, they don’t illustrate the TEM chain as clearly. The miscommunication example directly shows how a threat can lead to an error and an undesired aircraft state, and how teamwork and communication controls prevent or mitigate it.
