| 1) AM 251 doesn't get into soaring techniques too much. Solos during the summer are more common than during the ac year (because of weather).
2) There is always some wind (usually off the mountains). Thermals are pretty common, but vary in intensity (same with sink).
3) I never spent too long in any thermals (couple hundred feet), but that was because we had a tight schedule to stick to. One guy made it to 12,500MSL (released at 8500), then had to do 13 spiral dives to make it back to normal altitude. (The tower was angry, because he took more than an hour, and AM 251 flights are supposed to take roughly 20 minutes. He killed the schedule for that day.)
4) The cross-country gliders (TG-10A's) can be equipped with O2, but the normal soaring gliders (TG-10B's) are not normally equipped. I'm not sure about the aerobatic gliders (TG-10C's).
5)Probably, but I've never looked into it. |
