The first field landing lecture I attended was given by the late Lorne
Welch. The way he put it is there are three critical heights:

a. Ensure there are landable fields around.

b. Have a definite field picked.

c. Make a firm decision to stop trying to soar and land.

Over typical English farmland on a first cross country, (a) is 2000
ft, (b) is 1500 ft, and (c) is 1000 feet.

In a world championships in Argentina, (a) is irrelevant, (b) is 500
ft, and (c) when the wheel touches the ground.


My answer to (a.) is, ideally, ALWAYS!
