Spiral dive
The spiral dive should be considered an extreme manoeuvre. Practice spiralling with caution and
lesser sink rates to get a feel for the Tribe's behaviour. Weight shift and pull the brake on one side
gradually. Let it accelerate for two turns and you will enter the spiral dive. Once in the spiral, you
can control your descent rate and bank angle with weight shift and the outer brake.
WARNING! A pilot who is dehydrated and/or not accustomed to spiralling can lose consciousness in
a steep spiral dive! As with all types of aircraft, we advise you to assist the glider to exit from the
spiral dive in a controlled manner. Let the glider decelerate for one or two turns by applying outer
brake and/or weight shift.
B-stall
To quickly loose altitude without straining your body with G-force you can use the B-stall. Reach up
to the B-risers just below the maillons and twist your hands while gently pulling. It will be difficult
at first, but become lighter the more you break the airfoil. Once pulled, do not release immediately.
The glider needs to settle into a stable B-stall before releasing. On exiting the B-stall the Tribe has
a very gentle dive without deep stall tendencies. We advise you to release the B-stall symmetrically
with both hands in a decided manner.
Full stall, dynamic stall
This is an extreme manoeuvre and there should never be any need to perform one.
Do not take wraps with your brakes before entering a full stall. Keep your hands close to your body
during the stall, and lock them under your harness seat plate if necessary. In a stable full stall, the
canopy will oscillate back and forth. Before releasing the stall, raise your hands slightly and evenly
to fill the glider with air. If possible, let the brakes up when the glider is in front of you to avoid
excessive surge. The Tribe will slow down the surge on its own, but you may counter brake the dive
briefly for comfort if needed and then let up the brakes to regain airspeed. Be careful to not stall
the glider again when damping the surge.
Never attempt a stall and then change your mind and release the brakes, as the glider will surge
radically.
Deep stall (parachuting, stable stall)
The Tribe does not have a tendency to get into nor stay in a deep stall. Should this nevertheless
occur, put your hands on the A risers and push forward to gain speed. On some modern
harness/accelerator setups, you can reach the speed bar without using your hands. If so, push the
speed bar. Never try to steer out of a deep stall.
You can recognise a deep stall by the glider getting "mushy" and the airflow around your ears
decreasing. This situation is usually achieved by flying in turbulence or exiting a deflation with too
much brakes applied. A wet glider also has a higher deep stall tendency. If you pass some rain,
accelerate a little and never induce big ears in this situation.
