What does the term "Should" imply in procedural context?

In a procedural context, the term "should" implies a recommended procedure. It suggests that following the outlined action is advisable and strongly encouraged, typically based on best practices, expertise, or expected outcomes. This adds a level of expectation without enforcing it as a strict rule, thereby allowing for some discretion in compliance based on circumstances or judgment.

When "should" is used, it communicates that while the procedure is not obligatory, adhering to it is generally seen as the best course of action for achieving a desired result or maintaining safety and efficiency. This is particularly important in aviation and military operations, where key recommendations contribute significantly to effective performance and risk management.

The other options represent different levels of obligation or implications—mandatory procedures require strict adherence, optional procedures indicate no obligation to follow, and futurity relates to timing rather than guidance or recommendation. Thus, the understanding of "should" as a recommendation helps clarify the intended approach to following procedures within this context.
