To be legal we have to have the data(as I imagine you do unless the FAA let you have pretty some loose performance procedures.) As the above poster said, sometimes it's easy, sometimes it's not. Sometimes it's quick, sometimes it's not. But, at least on the A320, we set our data before start. We can and often do get and set new numbers, but that opens the door for errors as it's not as easy to cross check while taxiing. A new TPS could have a different flap setting for something as simple as a 200' intersection. Is it worth it at the last minute instead of a quick back taxi? Maybe, maybe not, but again...what has caused you an issue?

Now, what I really want to know is why do UA guys always ask for ride reports every time they check on a new freq.?
