Aerodynamic Efficiency: The design of an aircraft to minimize resistance and maximize speed and fuel economy.
Cabin Pressurization: A system that maintains atmospheric pressure within an aircraft cabin at a comfortable level, regardless of altitude.
Piston Engine: An internal combustion engine that uses pistons moving back and forth to generate power, commonly used in early aircraft.
