Recommended Practices are identified by the verb should and are not mandatory but considered desirable.

• A. should; not mandatory; desirable
• B. must; mandatory; essential
• C. may; optional; acceptable
• D. could; not mandatory; optional

Answer: (A)

The idea being tested is how policy language uses verbs to show obligation levels. When a practice is described as recommended, the verb should signals that taking the action is advisable and beneficial, but not required by rules or regulations. That’s why it’s not mandatory but considered desirable. If something were must or shall, it would be mandatory; if it were may or optional, it would be permissible but not required; could isn’t used to denote a firm recommendation in this context. So wording with should correctly conveys a non-mandatory, desirable practice. For example, aircraft should follow standard taxi routes when possible because it’s guidance to improve safety and efficiency, not a hard rule.
