Changes to Mystic Hill as a Result of Tree Clearing
Hi All
With Spring well and truly under way and increasing numbers of pilots visiting, it is timely to consider the changes that the recent tree clearing on Emily Spur has wrought.
This area has been logged for the first time in about a quarter of a century. The last time this was done, no paraglider pilot would entertain flying after about noon and before about 3:00 in the afternoon during summer. At the time, this included the highly competent pioneers of the sport in our area.
Already, pilots are noting changes in the way that Mystic behaves in thermic conditions. Hitherto reliable thermal trigger points have altered. Rough conditions are being noted on warm days.
It is concerning that, despite this, pilots have been observed flying very close to the cleared terrain. In some cases they are flying even closer to this bare ground than they would have to the tree tops prior to these trees being felled.
As tempting as it is, this is a very dangerous practice. Our safety margin is based (among other things) on our distance from terrain. This distance gives us opportunity to recover from loss of control before impact. Also, tree tops are relatively soft - a mishap close over pine trees generally means a relatively soft landing into cushioning foliage. Hard contact with cleared ground is far more likely to produce serious life-changing injuries.
Pilots are reminded that Mystic is an inland thermic site. It is not appropriate to fly as close to the terrain as one would at a laminar flowing coastal site. Rough turbulent conditions (including dust devils) can be anticipated at the height of the day, especially over cleared areas. In a way, Mystic has become as potentially dangerous as Spring Hill (near the ACT), another bare inland slope.
Pilots are advised to:
1. Maintain good clearance from terrain, especially more so over cleared areas
2. If low airtime/out of practice, consider carefully whether to launch once thermic activity has strengthened (maybe wait until later in the day when conditions settle)
Here's wishing everyone a safe start to the season proper. See you on the hill sometime!
Cheers!
