Description du décollage

The 750' launch (~2500ft MSL) is so named because it is 750ft vertically above the Andy Jackson Airpark LZ (same typical LZ as Marshall). It is a less popular alternative to the Marshall launch but has some key advantages: (1) It is readily accessible from Andy Jackson via the dirt 2N40 forest service road (~10 min, moderate clearance recommended) or a 0.6mi hike on a foottrail (~30min, steep). (2) Being lower elevation, cloud cover is less of an issue than at Marshall. (3) The quick access and quick flights in non-thermic conditions are well suited for beginners (and others) to rack up a large number of flights in a short time frame (such as four flights before noon). (4) On particularly thermic days it is possible for a launch from 750' to gain altitude up to and in excess of Marshall, defeating the need for a shuttle. Hanggliders do not seem to use this launch. The launch is a 50'x80' dirt and gravel patch sloping SSW at the south end of the large pull out. A streamer on a pole gives some indication of wind. The launch area is less forgiving than Marshall (but again suited for beginners). Non-thermic flights are about 3-4min to AJX. Site is maintained by the Crestline Soaring Society.

Météo

Summer conditions mid-day are usually very strong and can be dangerous. Dust devils blow through the LZ. Launch is popular in mornings when Marshall is in the clouds or there are low winds in the afternoon. Headwinds arrive here earlier than at the Marshall launch. Pilots are encouraged to launch in the first four hours after sunrise or the two hours before sunset. Sometimes sea-breeze fronts blow through, you can see them coming. And occasionally gust fronts from thunderstorms, though most thunderstorms form far enough back in the mountains as not to affect flying. wx info: http://www.crestlinesoaring.org/weather
