Abstract
The FAA regulation 14 CFR § 25.109 defines accelerate-stop testing for transport-category multiengine aircraft. It specifies that testing must include 2-second distance equivalent at engine failure speed VEF to simulate time taken for pilot to reject takeoff. However, pilot response time is widely debated. The purpose of this study is to determine pilot response time in rejecting a takeoff due to the failure of one engine during the takeoff roll.
Seven multiengine rated pilots participated in this study, which was conducted in a Baron 58 in the X-Plane 12 flight simulator. During the recruiting process, test subject candidates provided their ages and number of logged flight hours, both total and multiengine. The pilots were instructed to perform a normal takeoff but were not advised that they would experience an engine failure at VY speed during the takeoff roll. Their response times were determined based on their brake and throttle inputs, and the corresponding horizontal distances traveled by the airplane were recorded as well. It was determined that the number of logged multiengine hours and recent flight experience had significant effects on pilot response time. Although the median response time was less than two seconds, the mean response time that included outliers was a little over three seconds. The results also indicated that the horizontal distance traveled by the airplane was significantly correlated with pilot response time, which may prove to be critical for shorter runways.
