Pilot here . Have had one engine issue in my many hours in the air . Honestly before that , I was always a little nervous about how I would perform ifwhen something like that happened to me . But I did well I think . Looking back , if I just had the academic knowledge of what to do , had done nothing but memorize the checklist , I wouldn ' t have done as well . I know I wouldn ' t because instead of just reading , I actually executed the checklists in simulators and in actual flight , and the first few times I did , it was slow , and clumsy . After dozens of dryruns , I got better . So when the engine sputtered on me in the air , I just took a deep breath and got to work . There ' s a difference between just studying and training .
