The 'local' controller will issue the takeoff clearance, MOST competent pilots will read back exactly that in addition to an assigned heading. He will NOT say cleared for departure. Notice also the word 'cleared'. The tower controller will be the ONLY one who says that, and then only twice, "cleared for takeoff" and "cleared to land". When you are inbetween runways waiting to cross the departure runway (ATL) you remain twr frequency. When he DOES have you cross the dept runway, the phraseology is "XYZ212, CROSS 27R, join LIMA, contact gnd .75". He DOES NOT use the words 'cleared to cross' or 'you are clear to cross'. The reason came from the Tenereife disaster. The controller asked Pan Am to report 'clear' after back-taxiing. Van Zanten in KLM heard that and said "Okay, lets go" to the rest of the crew. The FO had a chance to save it by questioning the captain by saying 'Is he not clear, the Pan Am?' Captain, who was in a BIG hurry responded with 'Oh yes, he is clear'. MISUNDERSTOOD communication can have real consequence's.
Always a laugh listening to the 'professionals' read back the crossing instructions....'DEf132, cleared to cross 27R' Wrong, he didn't "clear" you at all. He issued a crossing instruction.
When I started as a controller, the .65 handbook was less than an inch thick. When I left in 2000 it was probably about 2 1/2. Almost every aircraft accident will have the FAA issuing some kind of revision. Reason? Lawyers for the victims will try to blame the FAA first, pilots and aircraft manufacturers next and right on down the line.
I am sure some of the current ATC folks can elaborate even more.
