In addition to local repair capability, which other factors must be screened for in avionic equipment?

The correct answer emphasizes the importance of the preservation method in avionic equipment maintenance and management. The preservation method plays a crucial role in how well equipment withstands environmental factors that cause corrosion, such as moisture, temperature fluctuations, and exposure to chemicals.

An effective preservation method ensures that the components are adequately protected against these elements, thereby extending the lifespan of the equipment and maintaining its functionality. This includes the application of coatings, sealants, and other protective measures designed to inhibit corrosion. Understanding various preservation techniques allows technicians to implement the most suitable strategies based on the specific environmental conditions and usage scenarios the avionic equipment will encounter.

While factors like the age of the equipment, parts availability, and the manufacturer's warranty are also important, they do not directly influence the effectiveness of corrosion prevention in the same way that preservation methods do. The approach taken to preserve the equipment can significantly impact its resilience against corrosion and overall reliability, making it a priority in screening avionic equipment.
