14is insufficient. For this reason NIVIUK have improved the EAR LOCKSYSTEM, which we already used in the first TAKOO.The TAKOO 4 comes with the EAR LOCK SYSTEM (ELS) as standard.In a simple and effective way, this improved system for pulling big earsassists the tandem pilot when performing this descent technique. Thisinnovation makes pulling or releasing ears simple, fast and easy.ELS enables the pilot to pull and release the ears as desired.ELS gives full steering control to the pilot with the ears applied.ELS lets the pilot use the ears as long as necessary with no physicaleffort at all.ELS allows the pilot to use the trimmers without concern or restriction.ELS locks in the ears and prevents accidental opening.ELS does not impede the conventional application of ears.The ELS system can easily be removed without affecting the rest of theequipment.To use the EAR LOCK SYSTEM simply pull the ear lock line downwarduntil the knot passes through the ELS (lock system); then move it slightlyhorizontally forward, locking the knot in the V groove. To release, pull theear lock line down and release the knot from the V groove. Then guide itvertically as it goes upward and back through the ELS (Lock System) It isbetter to release the two ears separately (asymmetrically).To perform big ears as a descent manoeuvre in the classic way, takethe external A-line on both sides, as high as possible and pull themdownward and outward. The wingtips will fold in. To release the ears,release the lines and they will reopen by without assistance. If thisdoes not happen, brake progressively on one side and then the other.Asymmetric reopening is recommended in order to avoid compromisingthe angle of attack, particularly flying near the ground.5.2 B-LINE STALLDuring this manoeuvre, the wing ceases to fly, it has no horizontal speedand the pilot has no control over the paraglider.The airflow over the profile is interrupted and the wing enters a situationsimilar to a parachutal stall.To enter this manoeuvre, the B-risers are gripped below the maillons andsymmetrically pulled down together (approx. 20-30 cm) and maintainedin that position.Initiating the manoeuvre is physically demanding because it can takesome strength to pull the risers down until the wing is deformed. Afterthis, the physical effort is less. Continue to hold the risers in position.Once the wing is deformed, its horizontal speed will drop to 0 km/h;
