Another thing that was stressed throughout the course, and one that certainly contributed to the Colgan Air crash, was the concept of sterile cockpit below 10,000 feet. Basically, the idea is for the pilot to focus 100 percent on flying the airplane and prevent errors by minimizing distractions during ground operations, takeoff, climb, descent, approach and landing. This is a concept general aviation pilots could also greatly benefit from. However, considering that many of the airplanes GA pilots fly don’t often climb beyond 10,000, the sterile-cockpit ceiling might be adjusted based on performance. For a piston single it could be something like 5,000 feet. Cockpit chatter and other distractions have caused multiple accidents and they’re easily prevented by ensuring that the full focus of the pilot goes toward flying the airplane during critical phases of flight.
