I'll keep my factory Continental tuned and = happy and my fuel tanks full.  And land on nice long paved = runways.

Michael,
 
What about the speed = differences between a Lancair and a glider?  Does that change the = calculation?
 
We are all taught to look for an open field to land = on.  Considering the altitude at which the decision is made and in = the time we have to make the decision, we probably can=92t tell too much = about stumps and rocks when we pick a field.
Should our decision making process = change?
