�Mental workload management is as foundational to aviation human factors as energy management is to stick-and-rudder skills, yet it is barely understood and often ignored. The same maneuver that one student flies effortlessly can saturate another, and the difference is rarely skill or motivation; it is workload, the moment-to-moment balance between task demands and available mental resources. This session gives flight instructors a working command of workload science: what it is, why it depends on the person-task relationship rather than the task alone, how stress and arousal reshape capacity, and what overload looks like before performance collapses. We translate decades of human-factors research (from NASA's Task Load Index to the arousal-performance literature) into instructional judgment a CFI can use on the next flight. Learning objectives: (1) Define mental workload precisely and explain why it varies between and within learners. (2) Identify the intrinsic and extrinsic factors that drive workload, including stress, arousal, fatigue, novelty, time pressure, and surprise. (3) Recognize the observable symptoms of cognitive overload (tunneling, working-memory loss, scan breakdown, communication degradation, startle) before performance fails. (4) Apply concrete workload-management strategies: arousal regulation, load sequencing, briefing, and training to automaticity. We ground every concept in the flight line, including a detailed SR22T transition case study, and equip instructors with a short field reference they can carry to the next lesson, followed by open Q&A. Key takeaway: a struggling student isn't 'behind the airplane' because they're slow or unmotivated; they're overloaded, and workload is the lens that makes a frustrating lesson diagnosable and fixable.
