As we know, the local President of the AOPA was killed last month in a

When I learned to fly in Jet Provosts, we practiced turn backs following 
engine failure. But the rules were simple:
1. Always turn into whatever crosswind you have; if you don't know the 
crosswind direction, don't do it.
2. Only turn back once you have reached the set speed /and/ altitude for 
the aircraft type.
3. Don't overbank at low speed
3. If you cannot make it to the runway, level the wings and crash land 
(actually eject, but we don't have that luxury)

The point is that you need a set amount of energy to turn back. It can 
be speed or altitude, they are interchangeable, so it really does not 
matter within limits whether you climb shallowly or steeply. But above 
all, you must practice the maneuver periodically (with care). If you do 
not practice it and you do not note the crosswind for each take off, you 
have no business turning back. Just land straight ahead.
