aim and heading share a recorded sense, so the question is not what they mean but which one fits. aim means “point or cause to go (blows, weapons, or objects such as photographic equipment) towards”. heading means “a line of text serving to indicate what the passage below it is about”. heading is the more common of the two in everyday English.
