Quality control of deicing/anti-icing fluids at the stages from production to their application at airports
The article presents the methods and procedures of quality control of deicing/anti-icing fluids used to protect aircrafts from ground icing, at the stages from production to their application in civil aviation. The characteristics of the main properties controlled in the laboratory of the Aviation certification center of GosNII GA, during the initial and periodic inspections of deicing/anti-icing liquids for compliance with the requirements of international specifications and domestic standards are described. The characteristics of deicing/anti-icing liquids controlled in the production of each batch, as well as quality indicators controlled during their acceptance, storage and use in civil aviation enterprises are given. The methods of measurement of controlled quality indicators in accordance with the technical conditions and international standards, the correct implementation of which is an important integral part of the continuous monitoring processes, ensuring, among other factors, the safety and regularity of aircraft flights in ground icing conditions, are described. Examples of detection in the laboratory of Aviation certification center of GosNII GA discrepancy of actual indicators, as well as characteristics of the main properties of deicing/antiicing liquids normalized values. Recommendations are presented that should help to reduce the level of potential risks in the conditions of mass operation by improving the quality control of work in civil aviation enterprises.
