to fly (usually announced by a slight forward surge as the wing dives
for speed). The second method is to activate the speed bar approximately halfway until
the wing regains forward flight. Again, there may be a slight surge forward in the wing as it recovers, but
recovery should be un-dramatic on the ATIS.
For either method, allow the surge to occur. Do not apply the brakes.
If your wing develops a tendency to enter this kind of stall frequently, send it to the factory for inspection. The wing or lines will likely have become stretched through
over-stressing.
2.6.2 Quick Turn
A quick turn may be necessary to avoid collision with another aircraft, or an obstacle. To accomplish it without spinning the glider, pull down the brake about 60 to 80% while SIMULTANEOUSLY
leaning hard in the direction of the turn. Smoothly release the brake and sit up after a turn of 90 degrees. If you hold the turn past 90 degrees, you will enter a steep spiral (section 2.5.4). If you try this at
low speed, you may spin the glider (see below).
2.6.3 Spin
A Spin is also known as a “negative turn“, “going negative“, or “over-climbing“. When it occurs, the flow of air over one half of the wing separates from the wing (also said to “detach“) and that side of the wing does not generate
lift. A tight spin may have the wing tip actually going backwards (negative). It almost always occurs as a consequence of the pilot holding in too much brake on one side during a slow turn but a spin can also occur if recovery from
other dramatic flight events is not managed properly (for example, a partial collapse or stall). The spin may occur very suddenly. To recover, immediately raise both controls all of the way up (HANDS UP!). The wing may recover
slowly, but will transition to normal flight. Again, the ATIS is designed to recover quickly and un-dramatically from this event if the pilot simply goes “Hands-Up“ immediately. As with an asymmetrical collapse (section 2.6.6), the
glider may surge forward or proceed through a turn as it recovers.
2.6.4 Full Stall
In normal flight it is almost impossible to fully stall the ATIS. The brake line length is set so that the glider will normally only enter a full stall if the pilot wraps the lines around his or her hands once or twice, and places both
hands straight down below their seat. Brake pressure will increase dramatically and the ATIS will fight to regain normal flight. If entering a stall deliberately, we recommend taking two wraps on the brake lines, straightening
both arms at the sides, and holding them tight against the body. The glider may full stall spontaneously if the pilot is flying very slowly in lift, and suddenly enters turbulence.
Once a stall occurs, the glider will move behind the pilot. HOLD IT IN THE STALL FOR AT LEAST 5 SECONDS or UNTIL THE WING IS AGAIN OVERHEAD. This is essential to allow
the glider to stabilise above you. If the controls are raised too soon, the glider may surge in front of, or even under, the pilot. This may cause you to fall into the
wing. When the glider is stable over your head (after at least 5 seconds) release both brakes quickly, smoothly and continuously to the top
of their travel. The glider will surge. It may require quick and gentle braking to prevent too much of a surge.
