In which ATA Chapter do the systems that protect control surfaces from movement by wind while the aircraft is on the ground belong?

The systems that protect control surfaces from movement by wind while the aircraft is on the ground are categorized under ATA Chapter 27. This chapter specifically deals with Flight Control Systems, which includes mechanisms that help maintain control surface integrity in various flight conditions, as well as those that prevent undesired movements when the aircraft is stationary. By including this aspect in Chapter 27, it ensures that safety measures are addressed in relation to the stability and readiness of the aircraft on the ground.

Other chapters address different aspects of aircraft systems and components. For instance, ATA Chapter 21 focuses on air conditioning and pressurization, while Chapter 32 covers landing gear systems. Chapter 44 is related to other systems, and thus is not applicable to control surface protections. Understanding the distinctions among ATA chapters is essential for proper identification and maintenance of aircraft systems.
