I took off from North Weald (SE England, U.K.) the other day and departed to the South East.
Its always a good idea when leaving North Weald on rwy 20 to climb out to the east. Once you are past the eastern side of the village you are outside Stansted's stub at 1500' and can continue to climb. By the time you are are abeam Stapleford, you'll be at 2000' and above their traffic. Once you get to Ongar, then you can turn south east.
