A demonstration and an overloaded learner

During a planned instructional session, a learner has successfully explained an aircraft instrument diagram on the ground. In a suitably supervised exercise, the learner then fixes attention on a single display and misses other relevant indications. The instructor initially considers repeating the entire demonstration at a faster pace. A later discussion reveals that the learner is trying to remember several new display labels while also performing an unfamiliar scanning task. The exercise is stopped at its agreed boundary before the situation becomes unsafe. The case supplies no aircraft-specific emergency procedure or authority for unsupervised flight. The instructional question is how to reduce avoidable cognitive load, preserve an accurate model and build evidence of coordinated attention before restoring additional complexity.
