Added phraseology up to the approach phase
* Cleared for takeoff runway ''number'', ''callsign''
| The controller authorizes the aircraft to take off.
| * This is the ''one and only'' clearance that gives a pilot permission to take off.* If you are holding short of a runway, this clearance also gives you permission to enter it and align. The controller does ''not'' need to tell you to ''line up and wait'' beforehand.* If the word ''immediate'' is added, you are only cleared for takeoff if you are able to do so within a very short time. Usually traffic is coming in on the same runway, so do not enter the runway if you are not ready for takeoff in this case.
