Best practice
Use "are to be" when you want to express a formal obligation, arrangement, or plan that is expected to occur in the future. It often implies a degree of authority or official endorsement.
Common error
Avoid using "are to be" when a simple future tense ("will be") is sufficient. "Are to be" adds a layer of formality and expectation that might not always be necessary or appropriate. Using "will be" can keep your writing more concise and direct.
