What is the objective of the clean aircraft concept?

The objective of the clean aircraft concept is to maintain an aircraft free of contaminants. This concept emphasizes the importance of ensuring that the aircraft's surfaces, particularly the wings and tail, are clear of ice, snow, or any other debris before takeoff. Contaminants like frost or ice can significantly alter the aerodynamic properties of the aircraft, leading to compromised lift and increased drag, which can ultimately affect performance, safety, and fuel efficiency.

By adhering to the clean aircraft concept, operators can help ensure that the airplane performs optimally, reducing potential hazards and enhancing overall safety during flight. This practice is essential in maintaining airworthiness and is a critical aspect of pre-flight checks, particularly in winter weather conditions.
