What does CDL stand for in aviation terminology related to airworthiness?

CDL stands for Configuration Deviation List in aviation terminology related to airworthiness. This list is an essential document used in the aviation industry that details any deviations from the certified configuration of an aircraft that are permissible for a specific time. The Configuration Deviation List allows operators to keep the aircraft safe and compliant while addressing issues that may arise during operation. It provides clarity on what deviations are acceptable and what maintenance or repairs need to be conducted to ensure the aircraft's continued airworthiness. This is particularly important for ensuring safety standards are met while also allowing for flexibility in operation under certain conditions.

In contrast, other terms such as "Critical Design Limit," "Continuous Deviation Log," and "Control Deviation Ledger" do not specifically refer to the established practice of maintaining acceptable operational parameters for aircraft configurations and do not hold the recognized significance in aviation airworthiness as the Configuration Deviation List does.
