Ridge

Ridge: A tongue of high pressure on a weather map. The opposite of a trough of low pressure.

Jet stream segments move with pressure ridges and troughs in the upper atmosphere. In general, they travel faster than the weather pressure systems, and maximum wind speed varies as the segments progress through the systems.

Internal thread on the oil pick up side to attach a filter cat ridge, as well as external threaded fitting to attach your hydraulic line feeding your pump. As seen in figure Layout 3.

For this we use 2 x Global Ridge Runts (unfortunately no longer available) and the tug being a WOT 4. This combination has caused people to sit up and take notice and it's a great feeling once we get air borne.

This we may readily give credit to, from the known fact of our little kestrel and the sparrow-hawk frequently flying off with a partridge, which is nearly three times the weight of these rapacious little birds.' ...
