Top 10 Questions for Deicer Finisher Interview

1. What are the different types of deicing fluids used in aircraft maintenance, and what are the safety precautions required when handling them?

• There are three main types of deicing fluids: Type I, Type II, and Type IV.
• Type I is a newtonian fluid and is made up of a mixture of ethylene glycol and water, and is effective down to -34°C.
• Type II is a pseudoplastic fluid and is made up of a mixture of ethylene glycol, propylene glycol, and water, and is effective down to -50°C.
• Type IV is a thickened fluid that has a higher viscosity than Type I and Type II, and is made up of a mixture of ethylene glycol, propylene glycol, and thickeners, and is effective down to -60°C.

• When handling deicing fluids, it is important to wear appropriate personal protective equipment, such as gloves, goggles, and a respirator.
• It is also important to avoid contact with skin and eyes, and to avoid inhaling the fumes.
• Deicing fluids can be harmful if ingested, so it is important to keep them away from children and pets.

2. What are the steps involved in the deicing process?

Step 1: Inspection

• Inspect the aircraft for any ice or snow accumulation.
• Identify the areas that need to be deiced, such as the wings, tail, and fuselage.

Step 2: Preparation

• Gather the necessary equipment and materials, such as deicing fluid, a deicing wand, and a scraper.
• Set up the deicing equipment and ensure that it is working properly.

Step 3: Application

• Apply the deicing fluid to the areas that need to be deiced.
• Use a deicing wand to spray the fluid evenly over the surface.
• Allow the fluid to dwell for the recommended amount of time.

Step 4: Removal

• Use a scraper to remove any remaining ice or snow.
• Use a clean cloth to wipe down the surface and remove any residual fluid.

Step 5: Inspection

• Inspect the aircraft to ensure that all ice and snow has been removed.
• Repeat the deicing process if necessary.

3. What are the different methods of deicing aircraft?

• There are two main methods of deicing aircraft: ground deicing and aerial deicing.
• Ground deicing is performed on the ground before takeoff.
• Aerial deicing is performed in the air while the aircraft is flying.

• Ground deicing is typically performed using deicing fluid.
• Aerial deicing is typically performed using heated air or infrared radiation.

4. What are the advantages and disadvantages of using deicing fluid?

Advantages

• Deicing fluid is effective at removing ice and snow from aircraft.
• Deicing fluid is relatively inexpensive.
• Deicing fluid is easy to apply.

Disadvantages

• Deicing fluid can be harmful to the environment.
• Deicing fluid can be corrosive to aircraft.
• Deicing fluid can be a fire hazard.

5. What are the different types of deicing equipment?

• There are a variety of deicing equipment available, including deicing trucks, deicing wands, and deicing platforms.
• Deicing trucks are used to apply deicing fluid to aircraft.
• Deicing wands are used to spray deicing fluid onto aircraft.
• Deicing platforms are used to elevate aircraft so that they can be deiced more easily.

6. What are the safety precautions that must be taken when using deicing equipment?

• When using deicing equipment, it is important to wear appropriate personal protective equipment, such as gloves, goggles, and a respirator.
• It is also important to avoid contact with skin and eyes, and to avoid inhaling the fumes.
• Deicing equipment can be dangerous if it is not used properly, so it is important to follow the manufacturer’s instructions.

7. What are the different types of deicing fluids?

• There are three main types of deicing fluids: Type I, Type II, and Type IV.
• Type I deicing fluid is a newtonian fluid and is made up of a mixture of ethylene glycol and water.
• Type II deicing fluid is a pseudoplastic fluid and is made up of a mixture of ethylene glycol, propylene glycol, and water.
• Type IV deicing fluid is a thickened fluid that has a higher viscosity than Type I and Type II deicing fluids, and is made up of a mixture of ethylene glycol, propylene glycol, and thickeners.

8. What are the factors that affect the effectiveness of deicing fluids?

• The effectiveness of deicing fluids is affected by a number of factors, including the temperature, the type of ice or snow, and the application method.
• Deicing fluids are most effective when they are applied at the correct temperature.
• Deicing fluids are more effective at removing ice than snow.
• Deicing fluids are more effective when they are applied using a spray nozzle than a brush.

9. What are the environmental concerns associated with the use of deicing fluids?

• The use of deicing fluids can have a number of environmental concerns, including the contamination of water sources and the release of harmful chemicals into the air.
• Deicing fluids can contain harmful chemicals, such as ethylene glycol and propylene glycol.
• Deicing fluids can contaminate water sources if they are not properly disposed of.
• Deicing fluids can release harmful chemicals into the air when they are applied to aircraft.

10. What are the future trends in deicing technology?

• There are a number of future trends in deicing technology, including the development of more environmentally friendly deicing fluids and the use of new deicing methods.
• Researchers are developing new deicing fluids that are less harmful to the environment.
• Researchers are also developing new deicing methods, such as the use of lasers and infrared radiation.
