Situational Awareness; Distraction
Deviation / Discrepancy - Procedural Published Material / Policy
Flight Crew Became Reoriented; Flight Crew Took Evasive Action
Human Factors
Takeoff off checklist was completed 'down to the line.'  Below the line at Runway....checked; we realized that the wrong runway was loaded (Runway 35). As we were cleared for takeoff from Runway 17; I changed the runway; but was distracted by 'company message' on the ECAM and attempted to review and clear it. I can't remember if I had the [Performance] page up or not when we got the ENG THR LEVERS NOT SET. I advised the captain to set TOGA which he did and we continued the takeoff. Above; 80 knots now; we then realized that the V speeds were not displayed on the PFD so I called them out from the paper [performance calculations] for Runway 17. The remainder of the takeoff and climbout proceeded uneventfully.Approaching the runway I was distracted by a nuisance ECAM message (company message) instead of ensuring the V speeds and flex temp were set for the proper runway. V speeds and flex temp are deleted when a new runway is loaded into the FMS and the new numbers need to be confirmed or manually loaded. I should have caught this had I not been distracted by the ECAM message and perhaps a little too rushed to get airborne.
Was given a last minute runway change with a reduced power takeoff (FLEX). I was doing the takeoff and my First Officer forgot to change data. When FLEX power was applied; we had a red warning light that wrong data for the runway had been entered. I went to full power (TOGA) and the warning went away. The whole event lasted less than 3 seconds. Slow down and ensure proper data is loaded.
A321 flight crew forgets to enter a new runway and V speeds after ATC changes the departure runway. The error is not trapped by the before takeoff checklist due being distracted by a company message. Without a FLEX temperature setting; TOGA thrust is required and the First Officer calls the V speeds from the paper performance calculations.
