Icing affects the basic principles of aerodynamics

 

     We already know that "icing" affects an aircraft in flight; however, many people don't understand the reason why icing could lead to a catastrophe. For this reason, I chose this topic for my blog.

     As ice forms on the surface of an airplane, it directly affects all four principles of aerodynamics. It increases drag by obstructing the aerodynamics of the airframe. It increases weight by accumulating throughout the airframe. Thrust is affected as it creates more resistance. Lastly, it affects lift as it disrupts the airflow around the wings. Additionally, when a wing is contaminated with ice, that wing will stall at a lower angle of attack, as illustrated above. Once all basic principles of aerodynamics are affected, it will become a real challenge to fly and handle that aircraft safely; therefore, this is not to be taken lightly.

     Airlines spend millions of dollars every year on deicing and ice-preventative technology. For this reason, the icing-related incidents are somewhat under control. If you ever have to fly where icing could be a factor, ensure to exercise all precautions. I strongly suggest staying off the skies if the conditions are severe.
