It has a static lift-weight ratio of 0.2-0.8 and thus requires relatively low minimum flying wind force, and this results in more kite flying chance and ever elegant fly effect.

One common problem OEMs have had with promotion forecasting is that most use static lift factors that may be weeks or months old, and may only provide the resolution or visibility at a high level.

Points out that the cubic law of pump power is not valid for the cooling water system of central air conditioning for it is an open system. The static head should be the lift in a cooling tower.
