(laterals) are attached to the vertical bridles. [Figure 7-12] The six-line system is preferable in windier conditions, as it allows the balloon to move within the framework created by the bridles and laterals, but keeps the ba lloon upright and confined to a relatively small area. The specific setup required is dependent on the intent of the tether and whether rides are being offered. 

In almost all cases, the manufacturer’s flight ma nual specifies procedures and techniques for tethering the balloon, and the prudent pilot is aware of these instructions and possible limitations prior to conducting a tether. 

Tether safety often depends more on flight team skills and preparation than anything else. The following te thering safety tips are drawn from the book, Hot Air Ba lloon Crewing Essentials,  by Gordon Schwontkowski, and is an excellent reference text for balloon pilots as well as crew. 

• Whether you use a commercially av ailable tether system or your own quality ropes matters less than how well and how thoroughly you prepare. Securely attach two or three tether lines minimu m to load rings, envelope carabiners, or other brand specific point on your equipment. 

• Triangulated wind protection is the goal. Attach tether lines to secure objects such as parked vehicles so that two lines always distribute wind loads. This protects you on all sides from turbulenc e and potential downdrafts from buildings. 

• Focus! Constantly watch weather conditions and line tensions for changes or needed adjustments. Listen to the crew for feedback and instru ction. Direct 

spectators and participants according to your needs and their safety rather than chatting with them. 

• Note and adjust for weather changes. Weather places great unnatural stresses on tethered balloons. Be prepared to suspend or cancel a tether at any moment due to changing weather. Allow extra time for packing lines and other tether equipment when considering whether to shut down. 

• Plan for any one line to fail or come untied with no notice. Create a backup plan you can implement immediately to maintain control and safety. 

• Watch for spectators and children who want to hang onto tether lines and ride them off the ground. Keep all noncrew away from lines; suddenly tight or rising lines pose risks for all concerned. At NO TIME should any crew member ever leave the ground (riding or hanging on the basket, holding ropes, etc.). 

• Devote one crew member exclusively to organizing passengers in a line far back from the balloon and tether lines. Select groups by number, weight, age, or an appropriate combination of factors. 

• Adding weight is necessary on landing and during passenger switches, giving many opportunities for someone’s toes or a foot to slip beneath a fully loaded basket. Keep everyone similarly clear of lines running to the basket or lower envelope. 

• Inspect lines frequently to ensure they are attached securely at both ends, particularly under heavy loads or in stronger wind conditions.
