Launch Area »

Pictorial Map showing Launch Area A (Bottom Area B no longer used due to fences)

A — is completely surrounded by trees, therefore caution is advised when assessing the wind strength and direction at launch. The true wind speed is extremely hard to judge. Often the wind at launch seams very light yet its perfectly soarable. If the wind on the ground is 10 - 12mph the true wind could be 25mph. Watch the trees behind takeoff to try to assist in assessing the wind speed.

The take off looks more daunting than it actually is, but a committed take off is essential as it is relatively shallow and to counter the turbulence near the trees. Start your run as far back against the fence near the stile as this is the steepest part. Treat it as a nil wind launch and maintain plenty of speed as you encounter the turbulence as you clear the trees. After flying over the trees turn right and head along the corner of the ridge.

Bottom Landing Areas »

At present we do not have an official landing site as the hill is not flown on a regular basis. The unofficial bottom landing sites are the sports field

(purple ) for paragliders and footpath in front of the hill (blue).

Our old landing field at Wainhill Farm (B) on pictorial map has new fencing in it which makes it an unsuitable landing field.

Flying

If the wind is off to the north the bowl to the right of launch works well. When flying south along the ridge, don’t cross the road without plenty of height as the air can be rough low down over Oakley Hill due to the cement works. Have about 750ft above take off before crossing the gap. Once past the quarries the ridge bends back into wind and works well in stronger winds, however in thermic conditions you could end up going down fast. There are lots of landing options here, best bet is to fly to the road to your left and land in the left hand field by the road.

XC Flights are limited due to the proximity to London CTR but there is a 10km ridge to explore and 15km flight to High Wycombe with plenty of good landing fields on the way.
