There are a few types of aircraft de-icing equipment that modern aircraft might utilize in the event of ice forming on the airframe. Because of the various factors that affect an airplane in flight, a pilot has to make a few considerations when using said equipment. The practicality of any aircraft de-icing system depends on the density of the ice in question, and how removal will affect the aerodynamic characteristics of the airfoil. Let’s consider the advantages and disadvantages of three main types of aircraft de-icing systems—pneumatic de-icing boots, chemical de-icing, and bleed air heating.

In this day and age, we believe that every vehicle should come with a functioning braking system in order to ensure safety. However, from the creation of the first plane to the advancements made during WWI, the early plane had no need for a complex braking system. It flew at such slow speeds that it only relied on the friction of the wheels touching the ground in order to come to a gradual stop. But as war created the need for faster and larger planes, a functioning brake system became necessary. Contemporary aircraft now typically have a dedicated brake unit for each of its main wheels in order for it to come to a stop in a timely manner.
