B-line Stall
Grasp the B risers at the quick links and pull them down simultaneously.
The paraglider will enter a B-line stall and drop backwards before stabilizing
overhead. The descent rate increases to 6 - 8 m/s. To exit the B-line stall
raise both hands together in a single, positive movement so that the risers
are at full extension. On releasing the B-risers, your METIS 3 should return
immediately to normal flight. An adjustment error, control error or special
aerological conditions may lead to a prolonged stall phase. In this case
pulling on the A-risers by 4 – 5 cm will initiate recovery of the paraglider.
Caution: unlike big ears and spiral dives (see above) a glider in a B-line is
in a true stalled position.
For this reason, a B-line stall should never be performed close to the ground.
6) Performance & Use of Brakes
The METIS 3 best glide is at trim speed (no brakes) – about 38 km/h. The
minimum sink rate is achieved by applying approx. 15% brake.
When using more than 30% brake the aerodynamics and the performance
of the glider deteriorate and the brake pressure rapidly increases.
Extremely high brake pressure indicates great risk of an impending
stall. This occurs at full brake travel (100% brake). In normal flying
conditions the optimum brake position, in terms of performance and
safety, is within the top third of the braking range.
7) Using trimmers
Your METIS 3/40 & METIS 3/42 is set up with trim tabs. This system
involves the additional pre-flight check of verifying that the trimmers are set
symmetrically.
For the following situations we recommend trim setting:
on/trimmers tight
 Steeply sloping launch
 Flight with a heavy passenger (Total Flying Weight 180-220 kg)
 Thermal flight
For the following situations we recommend trim setting:
off/trimmers loose
 Gently sloping launch
 Flight with a light passenger (Total Flying Weight 130-160 kg)
 Transition glides
8) Asymmetric or Frontal (Symmetric)
Collapses
Despite tests showing that the METIS 3 recovers spontaneously after
collapses, active piloting is recommended in the event of an asymmetric
or frontal collapse. Active piloting will reduce the loss of altitude and a change
of direction.
In the event of a frontal (symmetric) collapse:
 Bring both brakes down symmetrically to speed up reopening of the
leading edge, then immediately bring your hands back up to normal flying
position.
In the event of an asymmetric collapse:
 Keep the paraglider flying straight by leaning away from the collapsed side
and applying sufficient brake to maintain course.
 Speed up the reopening of the closed side by a single, positive input on
the collapsed side.
