Simply finsh the first training mission this should pop at the end the objectives are not that tricky at all,should take you about 5 to 10 minutes for this one.I can nearly guarantee this will be the first one you get.
It looks like a number of people are having trouble with this one unlocking for them, will anyone with any problems or suggestions to this problem please comment below,thanks
A comment straight form the Flight Team"For those having problems with achievements not showing up: Exit the game and log back in, and your most recent achievements should show up."
It seems that by continual play after the achievement should have popped can aid this problem.(Thanks NightHawk205)
