That doesn't work, F-nicrosil works like F-copper not like F-iron
I don't understand how you come to that conclusion, 6,84m.s^-2 is an increase in velocity of 6,84m.s meters per second every second it lasts.
Did you read what I said before saying the exact same thing for the second time?
Yes, because they reorient themselves to continue facing the right direction creating an uneven distribution of acceleration known as a rotation. But you'll note that they never have that issue when they they go in straight line while real life pilots do.
