Hi Guys, I have limited experience with the Technical side of aircraft (currently working as a ground handler at Cork) but have a small question about a flight I've just taken.
My Aer Lingus flight tonight EI845 (EI84X) operated with an A320-214 (EI-DEN) departed around 20:50 local from AMS tonight taking off from RWY 06 which measures 11,429ft. Those familiar with AMS and particularly of RWY 06 should understand my next point we immediately began rolling after turning onto RWY06, I spotted an aircraft on final and it became apparent the crew were accelerating from the taxiway onto the runway to get airborne as quickly as possible, I also noticed the flap setting was extended from CONF 2 to CONF 3 and the take-off roll was significantly shorter. I'm wondering is this standard practice? aren't the V1, V2, V3 speeds calculated from a selected Take-off Config?
Thanks for any info
