Specific Assurance and Integrity Level (SAIL)
SAIL (Specific Assurance and Integrity Level) is a risk-based framework used primarily for Unmanned Aircraft Systems (UAS) to determine the level of assurance and integrity required for their operations. The SAIL levels range from I to VI, with higher levels indicating more stringent safety and assurance requirements.
Design Assurance Level (DAL)
DAL (Design Assurance Level) is a classification system used in the certification of avionics and aerospace systems to ensure they meet required safety standards. DAL levels range from A to E, with A being the most stringent and E being the least.
Difference and Integration of SAIL and DAL and how they work together
SAIL and DAL serve different purposes but can complement each other in ensuring the safety and reliability of avionics systems.
SAIL focuses on the operational risk of UAS and determines the level of assurance and integrity required based on the specific context and environment of the operation. It is primarily concerned with the overall mission safety and regulatory compliance for UAS operations.
DAL focuses on the design and manufacturing processes of avionics systems and components, ensuring that they meet stringent safety standards based on their potential impact on the overall safety of the aircraft. DAL levels apply to the development and testing processes of individual systems and components.
