  • Abstract:
    This report documents the data and findings of a research study conducted to (1) collect an inventory of flightpath management (FPM) cognitive skills and examples of flightpath management knowledge for Part 121 operations and (2) investigate how susceptible FPM cognitive skills and knowledge are to degradation. A human-in-the-loop (HITL) simulation study evaluated how FPM cognitive skills and knowledge may degrade using a between-subjects design with B737 and A320 type-rated pilots. Degradation resulting from time away from flying was assessed by comparing 24 participants belonging to one of three groups: (1) individuals who meet requirements as defined in 14 CFR 121.439 pilot qualification for recent experience (n = 8), (2) individuals who used to qualify for recent experience but whose last flight in one of those aircraft was 6-12 months in the past (n = 8), or (3) individuals who used to qualify for recent experience but whose last flight in one of those aircraft was 12 – 24 months in the past (n = 8). The twenty-four participants completed seven scenarios in their aircraft type with twelve participants in the A320 and twelve participants in the B737. Study findings suggest that declarative knowledge of the functions and interactions of the Flight Management System (FMS) and autoflight systems, including the flight director, autopilot, autothrottles, and flight mode annunciations are more susceptible to degradation than other types of knowledge. The cognitive skills of collection, integration, and estimation appear more susceptible to degradation than prediction, planning, and communication. In addition, pilots who had been away from flying for 12-24 months appeared to execute cognitive skills of information collection, integration, and estimation at a slightly slower frequency. Findings also suggest degradation in skill and decay in knowledge was not strictly due to time away from flying but may also result from other factors. Potential mitigations include continual reinforcement and training in self-assessment.
