A 180 can only be safely done above 200 ft with good energy--just like a
rope-break. Even then, doing a 180 after over-shooting final is a good way
to stall/spin. One time while instructing, a student was way too high on
final and hadn't recognized how bad the problem was yet. By the time he
realized, he developed complete tunnel vision on the glider runway that was
now impossible to make. As we over-flew the glider runway, he wanted to try
a 180 from 100ft and 60mph. I took over, closed the spoilers, and few
straight ahead to the field you would use for a rope-break at 50 or 100 ft.
Just like planning for rope-breaks, you need to plan your missed-approach
options before you fly (or during instruction) what to do about being too
low or too high to make the usual runway.

In an overshoot situation in a glider I was taught that it is better to be
on
the ground overunning the landing area at 20mph rather than be too clever
trying fancy S turns at low altitude. Having said that if he had a tail
wind
component wast a 180 an option?
