Final answer:
The term 'should' in FAA Orders suggests a procedure is recommended, but not mandatory, allowing for some discretion or judgment.
Step-by-step explanation:
In Federal Aviation Administration (FAA) Orders JO 7110.10, JO 7110.65, and JO 7210.3, the term “should” is used to indicate a procedure that is recommended. This is different from the term “shall” or “mandatory” which indicates a procedure that must be followed. So, “should” implies that while the procedure is the suggested course of action, it may not be strictly required under all circumstances and may allow for some discretion or judgment in its application.
