You've made my point here. In any sentence, not ending with a question mark, the word tells you what you will do.Definition of shall:
"Shall" is a modal verb used to indicate future action. It is most commonly used in sentences with "I" or "we," and is often found in suggestions, such as "Shall we go?" "Shall" is also frequently used in promises or voluntary actions.
There is a difference between shall and must. If they want to change the definitions of words from dictionaries then they have to state what their words mean. Page 18? If there is an absence of them not supplying a definition for their changed meanings of words, the dictionary meanings are what we go by. Must is well .... must. We all know what that means. No ambiguity. Anything else besides must, does not have to be done.
421.1.7 says: "AFDD"..."shall be provided".
Shall is clearly not must. In short, with must you have to do it. Maybe page 18 clears the air. People need to know if they have to or it is optional.
When used ask a question it is suggestive of what you might do.
The regs don't suffix sentences containing shall with a question mark.
