When using a towline having a breaking strength more than twice the maximum certificated
operating weight of the glider, an approved safety link must be installed at what point(s)?

(Refer to figure 13.) What effect do the clouds mentioned in the weather briefing have on soaring
conditions?
A) All thermals stop at the base of the clouds.
B) Thermals persist to the tops of the clouds at 25,000 feet.
C) The scattered clouds indicate thermals at least to the tops of the lower clouds.
565. - PLT064

C) 7.
566. - PLT514
In addition to the standard briefing, what additional information should be asked of the weather
briefer in order to evaluate soaring conditions?
A) The upper soundings to determine the thermal index at all soaring levels.
B) Dry adiabatic rate of cooling to determine the height of cloud bases.
C) Moist adiabatic rate of cooling to determine the height of cloud tops.
567. - PLT173

stable?
A) On the upwind side of hills or ridges with moderate winds present.
B) In mountain waves that form on the upwind side of the mountains.
C) Over isolated peaks when strong winds are present.
568. - PLT494
How can a pilot locate bubble thermals?
A) Look for wet areas where recent showers have occurred.
