Fast access to information matters when a pilot must preserve awareness of the aircraft and the surrounding situation. The research question is not only whether an interface is usable, but what it asks of the user during a demanding task.
The Electronic Flight Bag engagement combined usability research, Cognitive Task Analysis, and high-fidelity LOFT simulation. Evaluation included workload assessment, realistic routes and diversions, and geographic edge cases.
The work identified more than 25 critical use errors in flight-planning and navigation workflows and reduced heads-down time by 30% compared with legacy multi-app workflows. Research across more than 200 airline operators also informed feature prioritization.
Scenario-based evaluation can reveal workload, coordination, recovery, and trust problems that a quiet interface review will not reproduce. A defined evaluation engagement connects those findings to design decisions without implying aviation certification.
