If the word immediate is added (eg. Cleared for immediate takeoff runway 28L), 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. | If the word immediate is added (eg.

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". | |||

For some reason ATC wants you to abort the landing; there might be traffic on the runway. Immediately abort your landing and follow the missed approach procedure appropriate to your aircraft. Usually the ATC will give some instructions like altitude and heading. As you have to redo your approach, you are requested to contact approach again. | For some reason ATC wants you to abort the landing; there might be traffic on the runway.

Remarks: | |||
* "Line up and wait runway xx" is used only when ATC can not issue a takeoff clearance immediately (e.g. because there is still traffic on the runway). Controllers must ''not'' use this command unless needed. | |||
* The phrase "(taxi into) position and hold" is no longer used. | |||
