BIG EARS
What: Folding the wing tips inward by pulling down the outer A-lines, reducing the effective wing area.

Aerodynamic effect: Lift decreases, drag increases; forward speed usually stays the same or drops slightly; sink rate increases.

Purpose: Controlled rapid descent, leaving thermals, or preparing for landing.

Risks/notes: Angle of attack is lower, stall margin is reduced; combining with speed bar increases sink but also collapse risk. Should be practiced in a controlled SIV environment.

Speed Bar Use (Accelerator)
What: Foot-operated system to increase trim speed by pulling the leading edge down via the A-risers.

Effect: Higher forward speed, reduced angle of attack.

Purpose: Penetrating into headwind, increasing glide efficiency, or combining with Big Ears for rapid descent.

Risks/notes: Reduced brake authority, higher sensitivity to collapses, especially at low altitudes or turbulence.

Spiral Dive
Definition: A steep, continuous turn that rapidly loses altitude.

Purpose: Practice high-G flight and rapid descent control.

Execution: Apply continuous brake on one side and shift weight to the same side.

Expected Reaction: The wing dives steeply, G-forces increase significantly.

Recovery: Gradually release brake and return weight to center.

Asymmetric Collapse
What: One side of the wing folds partially or completely, creating an asymmetric wing shape.

Effect: The wing banks toward the collapsed side, inducing yaw and turn; the inner wing may stall.

Purpose: Not a goal in itself—SIV training teaches recognition, control inputs, and recovery.

Risks/notes: Quick and correct input is required; excessive or panicked inputs can worsen the situation.

Symmetric Collapse / Front Stall
What: The entire or major part of the wing’s leading edge collapses symmetrically.

Effect: Forward pitch drop, speed reduction; the wing may surge and oscillate.

Purpose: Practice recovery techniques, understand pitch behavior, and learn timing for reopening.

Risks/notes: Over-aggressive brake input during recovery can cause further instability.

Spin
Definition: One side of the wing stops flying while the other side keeps moving forward.

Purpose: Practice spin recovery caused by excessive brake input.

Execution: Pull one brake fully down.

Expected Reaction: The glider rotates around its center with minimal forward movement.

Recovery: Quickly release the brake and return to symmetrical flight, using weight shift if necessary.

Wingover
Definition: A series of alternating, increasingly steep turns.

Purpose: Learn dynamic flight, rhythm control, and energy management.

Execution: Initiate gentle turns, progressively increasing brake input and weight shift.

Expected Reaction: Each swing becomes higher until the wing passes above the pilot.

Recovery: Reduce inputs and return to level flight.

Full Stall
Definition: Bringing the wing to a complete stop in the air.

Purpose: Understand critical angle of attack and recovery techniques.

Execution: Pull both brakes fully down until the wing folds back.

Expected Reaction: The wing falls behind the pilot, forward flight stops completely.

Recovery: Gradually release brakes, controlling the forward surge.

Backfly
Definition: Flying backwards with the wing overhead but in reverse airflow.

Purpose: Learn post-stall control and stability before returning to forward flight.

Execution: After a full stall, hold brakes in a position that keeps the wing in stable backfly.

Expected Reaction: The leading edge remains above, airflow comes from the trailing edge, and the pilot drifts backward.

Recovery: Slowly release brakes until forward flight resumes, controlling the surge.

SAT
Definition: The wing flies a horizontal circle while the pilot’s center of rotation is offset from the wing’s center.

Purpose: Entry-level acro maneuver to understand advanced energy management.

Execution: Start a turn, shift weight to the inside, progressively increase inside brake until the wing locks into SAT.

Expected Reaction: The wing remains open and stable, flying a circular path while the pilot feels sustained G-forces.

Recovery: Gradually release brake, return weight to center, and resume normal flight.
