This left an intermediate altitude at which a small gun could not be used because the range to the aircraft was too far, and a larger gun could not be used because the targets were moving too fast.

HAWP systems that are flown must climb through all intermediate altitudes up to final working altitudes-being at first a low- and then a high- altitude device.

In many ways they are designed to complement each other; 2K11 is effective at long ranges and high altitudes, 2K12 at medium ranges and intermediate altitudes.

At intermediate altitudes, the air still contains approximately 20.9% oxygen, but the barometric pressure and thus the partial pressure of oxygen is reduced.

Of the various land-uses in the region, soil erosion is most severe at intermediate altitudes where barley, corn, tubers, etc. are cultivated.

The distribution of pyroclastic ash depends largely on the direction of wind at intermediate and high altitudes between approximately 4.5 - 13 km.

In general, the subsoils vary from fluvial type at low altitudes, to lime bearing at the higher altitudes, and sandy type at the intermediate altitudes.

At intermediate altitudes the craft would momentarily transition from one regime to the other, during which time one side of the vehicle would be entirely supported while the support was disappearing under the other.

The Maritime pine (Pinus pinaster) is found at an intermediate altitude and on generally siliceous soil, which in Galicia goes down to sea level and inland alternates with Pyrenean Oak.

Stopping at an intermediate altitude overnight can alleviate or eliminate occurrences of AMS.
