Due to the high load on the B-lines, sometimes it is very difficult to do B-stall a
tandem. This is why you may also try to perform B-stall by grabbing the handles on
the B-riser and pulling them down. The handles activate a special reduction
mechanism to lessen the force necessary to make a B-stall. To exit a B-stall, release
the riser fast, to prevent any chance of entering deep stall, especially with light wing
loading.
14.7 BIG EARS
Height can be lost in a controlled way by collapsing both tips. To do this, grab the
outer-most A-line (attached on its own riser) on both side and pull down until the tips
collapse. Pulling one side at a time may be more comfortable and easier, especially
for lighter pilots. This should fold about 30% of the wing in total. It is possible to steer
with weight shift.
Big ears yield around 7 m/s sink-rate with about 45-km/h forward speed. To exit,
release the outer A-lines.
Sometimes, it may be necessary to apply a little brake to open the tips. If using the
brakes to open the tips, it is best to open one tip at a time to avoids reducing your air-
speed.

14.8 DEEP STALL OR PARACHUTAL STALL
Under normal flying conditions the Play 42 has no tendency to enter deep stall. All
gliders can however, under certain conditions, enter and stay in deep stall
configuration (as a result of ageing of materials, improper maintenance or pilot
induced).
14.8.1
Signs of parachutal stall
The pilot has very little or no forward speed and no wind in his/her face.
The glider is fully open yet the cells are bulging in and not out on the bottom
surface.
The glider might have a very slow turning sensation.
You will have an increased vertical descent.
14.8.2
Exit from parachutal stall
It is important to recognize this situation. Most accidents involving parachutal stall
occur because pilots fail to realize a deep stall situation.
The best way to exit a parachutal stall is to pull all the A risers down to get the wing
flying again. The pilot can pull the A riser down until the wing starts to fly again. The
moment the wing starts to fly the pilot should release the A riser or the wing might
suffer a frontal collapse.
Alternatively the pilot can release the trimmers to lower the angle of attack and get
the wing flying again.
