So very true. If you read a, “How do I…?” post, it is not acceptable to simply respond with, “Don’t. Do this instead.”
In some cases it may be appropriate to explain that what the user is asking to do is not possible. In that case it is important to explain that that is the case and the closest alternative may be an add-on or mod that allows the task.
In others, it may be a case of trying to do something in an airplane that does not support what the user is after. “How do I autoland a 152?” would be a good example. Education is what this forum is about and sometimes alternative solutions need to be offered, but, PLEASE, answer the question first, then offer the alternatives.
