This site is a local soaring ridge and a school training location, accessible only to members. It is situated in the UK and has a modest height of 245 meters with a horizontal distance of 45 meters. The site record for distance is 0.7 km and 11.8 km for different regions. Takeoff: The takeoff area is a large, flat, open space. A daily site fee of £5 is required, payable via PayPal to fly@greendragons.co.uk. Keep your email receipt as proof of payment. Set up your equipment off to one side and move to the takeoff area only when you are ready to fly. This site is suitable for soaring and accuracy practice. Landing: You can land at the bottom, top, or on the slope. Be cautious of hazards such as rabbit holes and a fence line running left to right in front of the takeoff area. Land anywhere out to the front, top land, or slope land. Access: To access the site, visit the Green Dragons Clubhouse and inform a staff member that you will be flying. They will direct you to the site. Remember, this is a members-only site. Weather Hazards: Do not fly if the wind is too far off to the left, as the rotor from the hill makes the site unsafe. Flight Regulation: The site is near Biggin Hill Airspace, 1 km behind the takeoff. The maximum height allowed is 2500 ft or 762 m AMSL.
