I have a question about ATC: If one assumes that the runway that an aircraft is to use for takeoff is clear, there is no conflicting traffic if it takes off now, and the pilot insists that the aircraft can take off from the intersection where it is, does ATC have the right to refuse to give a takeoff clearance on the basis that it looks like an odd place for the aircraft to start from?
Flying a multi engined helicopter from an airport we rarely visited, procedures conformed with heavy jet take off procedures such as V1 and reject distances, taxied to an intersection for take off on the runway and the tower called "you know you only have XXX metres from there?". All was good, but it showed an on the ball tower controller who understood helicopter operations, likely because of the resident helo operators, thumbs up Essendon.
