This page lists some common phraseologies used in the communication between pilots and [[Air traffic control|ATC]]. Items in ''italic'' need to be replaced by the relevant information; lists are dialogues between the pilot and the controllers.
For a detailed tutorial in ATCing, please take a look at the [[ATC Tutorial]].

If '''Remark:''' the word immediate is added (eg. Cleared for immediate takeoff runway 28L), controller might ask you are only cleared for takeoff if you are able to do so within follow an aircraft or to perform a very short time. Usually traffic is coming in on maneuver after another aircraft has cleared the same runwayway (''conditional clearance''). In that case, so do not enter (s)he will say ''"After the runway if you are not ready for takeoff in this case''aircraft type''..."''.
Remarks:* ATCs may issue this clearance even if you're not still on the runway. In that case, you are authorized to enter the runway, align and then take off - there is no need to ask/wait for a clearance to "line up". ==Takeoff and departure = Cleared to land runway two-eight-center ={| class="wikitable"! scope="col"| PhraseologyYou are cleared to land at runway 28C.
