I wanted to add one point.
As others have said fly the aircraft etc but if you can despatch a pan or mayday (I think it should be a mayday) make every effort to do so.
I good friend of mine died after an engine failure. Whilst the circumstances of his arrival were not fully understood, it is probable had AT known of his plight he would have been found in time to save his life. As it turned out the rescue services did not arrive at the scene until some considerable time after. There was no need for this to have been the case (a very easy site to get to) - it was simply that no one knew the aircraft was down.
It is not brave or clever to believe you will pull off the perfect landing, the fact is even if every is looking good you can never been absolutely certain whether there is a pot hole or some small obstruction in an otherwise perfect field that might be enough to turn the aricraft over.
Make the call if you possibly can.
