To get the RTOW charts out (if you have them, if you have LPC laptop you won't) would take just as long as starting up the laptop and cross checking the numbers.
Agree on having to look at the rtow charts as well however If you aint climb or runway limited in the first place (as they used ass temp),they wouldnt be limited using full thrust...obstacles and slope are the same..
Airbus specifically warns that the speeds must not be mixed and matched, so best to take a moment and update the FMGS with the updated information.
Not flying Airbus but that IS exactly my point.
It the same as ohhh the runway is now wet..let s just cut 10kts off V1..
