The U.S. Air Force is changing its policies regarding pregnant pilots and their authorization to fly. 

The new policy restricts pilots from flying jets during the early weeks of their pregnancies due to certain health risks. The new rules focus on service members in their first trimester of pregnancy. One of the most significant changes in these new aviation guidelines involved prohibiting pregnant pilots from flying aircraft within the first three months of pregnancy. It also limited the granting of waivers for those who wish to fly while pregnant.
