Drying and preservation procedures are essential to remove ___ and control ___?

The significance of drying and preservation procedures in avionics comes from the need to manage moisture effectively. Moisture is a primary contributor to various forms of corrosion, particularly in electronic equipment and aircraft structures. When moisture is present, it can lead to electrochemical reactions that promote corrosion, potentially damaging vital components. By thoroughly drying the equipment and removing any residual moisture, the likelihood of corrosion is significantly reduced, thus enhancing the longevity and reliability of avionics systems.

Controlling corrosion is essential not only for maintenance but also for safety in aviation operations. Ensuring components are dry helps to create an environment where corrosion cannot easily take hold. Therefore, the statement reflects a fundamental principle in avionics maintenance: manage moisture to control corrosion. This highlights the interconnectedness of these two factors in preserving the integrity of aviation technology.
