With an increase in weight, your …

Icing is hazardous to any aircraft, prop or jet. Here's why: 1) Weight. TYPES OF ICING. Check out this chart from AOPA’s icing guide with various types of cloud types and temperatures you will most likely see icing: Hopefully, I’ve convinced you to report often. Icing is insidious. They are Type I, II, III, and IV. Anti-icing fluids are similar in composition except that they also contain polymeric thickeners. These phenomena do not necessarily occur together. Deicing fluids are typically ethylene glycol, diethylene glycol or propylene glycol based fluids containing water, corrosion inhibitors, wetting agents and dye. Even with de-icing capability, the airlines will take precautions by increasing the landing speed to account for poor airflow. In aviation, icing conditions are atmospheric conditions that can lead to the formation of water ice on an aircraft.

So what are the four types … But, now for the hard part. The three main types of ice accretion, in order of their hazard to flying, are as follows: CLEAR ICE.

We generally recognize 4 main types of aircraft icing. Aircraft deicing/anti-icing fluids consist of four types. Rime Ice Rime ice can, however, pose a hazard for aircraft without de-icing or anti-icing equipment or with non-activated de-icing equipment. You should be afraid of it if you don’t have de-icing capability.

As ice accumulates on your aircraft, weight increase. Ice accretion can affect the external surfaces of an aircraft – in which case it is referred to as airframe icing – or the engine, resulting in carburetor icing, air inlet icing or more generically engine icing. Propylene glycol-based fluid is more common because it is less toxic than ethylene glycol. Both airframe and engine icing have resulted in numerous fatal accidents in aviation history. Read on for more in depth knowledge on each of these types of ice. Types of In-flight Airframe Icing Accidents There are two main origins of accidents and serious incidents involving airframe icing: General aviation aircraft that are not equipped with ice protection systems but are flown in icing conditions may encounter enough icing at cruise altitudes to overwhelm the aircraft power reserve, leading to an inability to maintain altitude and/or airspeed. Clear ice or glaze ice is a heavy coating of glassy ice which forms when flying in areas with high concentration of large supercooled water droplets, such as cumuliform clouds and freezing rain. The Aviation Weather Center does an excellent job of collecting icing PIREPs. 1. Types of Aircraft Icing. Even a trace amount will disrupt the flow of air over your wing. Deicing fluids come in a variety of types, and are typically composed of ethylene glycol (EG) or propylene glycol (PG), along with other ingredients such as thickening agents, surfactants (wetting agents), corrosion inhibitors, colors, and UV-sensitive dye. "Clear ice," on the other hand, is a more hazardous ice type, as it is denser than rime ice and can spread over a part of the airframe’s surface that is not protected by de-icing or anti-icing equipment. Rime ice, clear ice, mixed ice, and frost.
