DEPARTUREThe word “takeoff” is restricted to the actual takeoff clearance or its cancellation, e.g., “UPS 6078cleared for takeoff, cancel, I say again, cancel takeoff.” In all other cases it is referred to as“Departure,” e.g., “UPS 6078, are you ready for (immediate) departure?”
To stop a takeoff inemergency conditions, the phraseology “UPS 6078 stop immediately” is used twice. For pilots torequest takeoff clearance, use the phraseology, “UPS (flight number) ready for departure.”If takeoff clearance cannot be given, the aircraft may be instructed to “Line up,” “Line up runway(number)” or “Line up and wait” (i.e., the equivalent of “Taxi into position and hold”). In these cases,the aircraft may taxi onto the runway and must wait for takeoff clearance.Flight crews may also be given “conditional” instructions or “conditional” clearances which willcontain the call sign, the condition and the clearance or instruction. For example: “UPS 6078 afterL-1011 on short final, line up.” The crew would have to read back the conditional instruction and afterthe landing L-1011 passed, the aircraft could line up on the runway and await takeoff clearance.
