Is differential pressure measurement necessary for aircraft de-icing operations?
You are likely familiar with the task of removing snow that has accumulated on a car or ice that has formed on the windows. The same task is necessary for aircraft when it starts to snow or ice forms. The process of removing ice or snow from an aircraft is known as de-icing. De-icing is performed in specially designated de-icing areas and is scheduled just before the aircraft takes off. This is because ice and snow not only increase the weight of the aircraft but can also impair its aerodynamic characteristics. De-icing is carried out using a liquid that contains at least 50% glycol mixed with water, and there are a total of four types of liquids that can be used for de-icing. At Amsterdam's Schiphol Airport, the mixture used for de-icing is stored in large heated tanks and is pumped into what is known as "Safeaeros" before being used on the aircraft. Safeaeros is a type of spray vehicle specially developed for this purpose. At Schiphol Airport, four Safeaeros vehicles are used per aircraft (two in front of the main wings and two behind the tail).
