Why is it so difficult for some pilots to execute a 180 degree return?
Because they want to get home....
Mary that is one aspect but there are more
Maybe they think things will improve if they hold on a bit?
maybe they see it as defeatism to go back
Maybe they are not good instrument pilots and having got into IMC conditions take all their brain power to keep straight and level?
a turn back is not always a guarantee that you will meet the conditions you left ?
Maybe even vanity comes into it " Jack in the plane ahead has got through why can't you?"
The challenge??
but yes get home itis is a major element in not turning back
