Top 10 Questions for Deicer Tester Interview

1. What are the different types of deicing fluids used in aviation and their advantages and disadvantages?

• Type I: Ethylene glycol-based fluids are the most common type of deicing fluid used in aviation. They are effective at removing ice and snow from aircraft surfaces, but they can be corrosive and have a high freezing point. They are also more expensive than other types of deicing fluids.
• Type II: Propylene glycol-based fluids are less corrosive and have a lower freezing point than ethylene glycol-based fluids. However, they are also less effective at removing ice and snow from aircraft surfaces. They are also more expensive than Type I fluids.
• Type IV: Aircraft deicing fluid Type IV contains between 70% and 85% propylene glycol and between 15% and 30% dipropylene glycol. It is a safer alternative to Type I and Type II fluids but is less effective at lower temperatures.

2. What are the different methods used to apply deicing fluids to aircraft?

Ground-based deicing

• Pump truck deicing: A pump truck is used to spray deicing fluid onto the aircraft.
• Fixed deicing system: A fixed deicing system is installed at the airport and sprays deicing fluid onto the aircraft as it taxis.

Airborne deicing

• Airborne deicing: Deicing fluid is sprayed onto the aircraft while it is in the air.

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

• Type of deicing fluid: The type of deicing fluid used will affect its effectiveness. Type I fluids are more effective than Type II fluids, but they are also more corrosive.
• Application method: The application method will also affect the effectiveness of deicing fluids. Ground-based deicing is more effective than airborne deicing.
• Environmental conditions: The environmental conditions will also affect the effectiveness of deicing fluids. Deicing fluids are less effective in cold weather and when there is a lot of snow or ice on the aircraft.

4. What are the safety precautions that must be taken when using deicing fluids?

• Deicing fluids are corrosive and can cause skin and eye irritation. It is important to wear gloves and eye protection when handling deicing fluids.
• Deicing fluids can be flammable. It is important to keep deicing fluids away from open flames and other sources of ignition.
• Deicing fluids can contaminate water sources. It is important to dispose of deicing fluids properly.

5. What are the different types of deicing equipment used in aviation?

• Pump trucks: Pump trucks are used to spray deicing fluid onto aircraft.
• Fixed deicing systems: Fixed deicing systems are installed at airports and spray deicing fluid onto aircraft as they taxi.
• Airborne deicing systems: Airborne deicing systems are installed on aircraft and spray deicing fluid onto the aircraft while it is in the air.

6. What are the different types of ice and snow that can form on aircraft?

• Rime ice: Rime ice is a thin, white ice that forms when water vapor freezes on the aircraft’s surface.
• Clear ice: Clear ice is a thick, transparent ice that forms when liquid water freezes on the aircraft’s surface.
• Mixed ice: Mixed ice is a combination of rime ice and clear ice.
• Snow: Snow is a collection of ice crystals that can form on the aircraft’s surface.

7. What are the different methods used to test the effectiveness of deicing fluids?

• Cold chamber testing: Cold chamber testing is used to test the effectiveness of deicing fluids in a controlled environment.
• Field testing: Field testing is used to test the effectiveness of deicing fluids in real-world conditions.

8. What are the different regulations that govern the use of deicing fluids in aviation?

• International Civil Aviation Organization (ICAO): ICAO has developed regulations that govern the use of deicing fluids in aviation.
• Federal Aviation Administration (FAA): The FAA has developed regulations that govern the use of deicing fluids in aviation in the United States.

9. What are the future trends in deicing fluids?

• The development of new deicing fluids that are less corrosive and have a lower freezing point.
• The development of new application methods that are more effective and efficient.
• The development of new regulations that are more stringent and protective of the environment.

10. How do you stay up-to-date on the latest developments in deicing fluids?

• Attending industry conferences and seminars.
• Reading trade publications.
• Networking with other deicing professionals.

A Deicer Tester is an individual who is responsible for conducting experiments and evaluating how well an aircraft deicer works. Their key job responsibilities are as follows:

1. Conduct experiments on aircraft deicers

This includes selecting the appropriate test methods, setting up the experimental apparatus, and conducting the experiments. The Deicer Tester must also ensure that the experiments are conducted safely and in accordance with relevant regulations.

• Select the appropriate test methods
• Set up the experimental apparatus
• Conduct the experiments
• Ensure that the experiments are conducted safely and in accordance with relevant regulations

2. Evaluate the performance of aircraft deicers

The Deicer Tester must evaluate the effectiveness of the deicer by assessing the amount of ice and snow that is removed from the aircraft, and the time it takes to remove the ice and snow. They must also identify any potential problems with the deicer, such as corrosion or damage to the aircraft.

• Assess the amount of ice and snow that is removed from the aircraft
• Determine the time it takes to remove the ice and snow
• Identify any potential problems with the deicer

3. Report on the results of experiments

The Deicer Tester must prepare reports on the results of their experiments. These reports should include a description of the methods used, the results obtained, and the conclusions that can be drawn from the results.

• Prepare reports on the results of their experiments
• Include a description of the methods used, the results obtained, and the conclusions that can be drawn from the results

4. Keep up-to-date on the latest developments in aircraft deicing technology
