abstract="We examined the potential vulnerabilities of pilots flying a mixed fleet of two different aircraft types. A &quot;worst case&quot; scenario was evaluated in which a pilot, flying one type exclusively, would need to fly the different type, after 6 months without any recurrency training on the latter. These circumstances invite negative transfer of habits in the &quot;old&quot; aircraft, to performance in the &quot;new&quot; aircraft&quot;. Documents of both aircraft were evaluated to establish those aspects of design and procedures differences that invite such negative transfer; a list of 36 such &quot;vulnerabilities&quot; were identified. Then 40 active commercial airline pilots from a US carrier participated in an evaluation of such negative transfer between two different types within the fleet. The sample was divided into 2 groups each of which normally flew one of the types and not the other. After training on the &quot;new&quot; type, each pilot returned to either 3 or 6 months of flying exclusively with their &quot;old&quot; type, and then returned for simulator evaluations on the &quot;new&quot; type that were targeted to reveal the 36 vulnerabilities. Even with power-sensitive statistical analyses, only slight evidence for negative transfer was found. Those areas where such transfer did emerge were targeted for recommendations of either procedural harmonization or minor design changes.<p /><p>Language: en</p>",
