They also describe the conditions used to determine the manufacturer's published speed. Historically, in aircraft certification, dynamic VMC has been determined under the following conditions outlined in historical 14 CFR part 23, section 23.149: ⦁ Maximum available takeoff power initially ... each engine (section 23.149(b)(1)). VMC increases as power is increased on the operating engine. With normally aspirated engines, VMC is highest at takeoff power and sea level, and decreases with altitude. With turbocharged engines, takeoff power, and therefore…

First, adjust the power to the maximum controllable level on both engines. Because the left engine is the only engine delivering thrust, the yaw increases to the right, which necessitates application of additional left rudder application. Figure ... worldwide. Its application is illustrated in column A while automatic/naturalistic decision-making is shown in column B. The failed engine is the side that requires no rudder pressure, in this case the right engine. Second, having identified the failed right…
- Chapter 13: Transition to Multiengine Airplanes › Engine Inoperative Flight Principles › ⦁ All propeller controls in the recommended takeoff position throughout VMC determination
determination of VMC in certification is solely concerned with the minimum speed for directional control under a very specific set of circumstances, and not the optimum airplane attitude or configuration for climb performance. During dynamic VMC determination in aircraft certification ... cuts of the critical engine using the mixture control are performed by flight test pilots while gradually reducing the speed with each attempt. VMC is the minimum speed at which directional control could be maintained within 20° of the original…

overrun available to land on. The use of wing flaps for takeoff virtually eliminates the likelihood of a single-engine climb until the flaps are retracted. There are two time-tested memory aids the pilot may find useful in dealing ... with engine-out scenarios. The first, “dead foot—dead engine” is used to assist in identifying the failed engine. Depending on the failure mode, the pilot will not be able to consistently identify the failed engine in a timely manner…
