one last thing that needs to be clarified.

engine out approaches are overhead approaches

if your engine fails you want as much altitude over the field to ensure landing

if you are out of range you are out of luck

so overhead and engine out approaches are one and the same thing

there is a wonderful app that goes on the ipad called xavion 99 bucks 

and could save your life

its a computerized constantly changing nearest airport approach with engine out

is available on the mac store. It takes about 5 hrs to enter your engine glide and performance

then you can see the highway on the sky with the overhead approach to the closest airport available

highly recommended
