Aileron, I suspect the reason you've had no reply in 3 hours, when everyone reading this forum knows the answer, is that they are puzzled as to what you are really asking. Because this is the sort of stuff that is taught almost on day one of a PPL.
Your profile is no help in finding your qualifications, so one doesn't know whether one has missed some nuance that would be puzzling a professional (there are always nuances!) or whether you are just starting out and don't yet have access to the books that explain it all. In which case, what's the interview for?
More background please, Aileron.
