I'm a North Weald resident too and RD has it just right. follow the M25 and turn left just before the M11. You will see the white splodge that is the market before you see the airfield. Jets tend to fly the circuit at 1000' QFE, so it you stay nice and tight at 800', you will have no trouble. Don't overfly North Weald village.
Enjoy your day, we have a wide variety of aircraft resident here.
