Maneuvering Loads and the V-n Diagram. The V-n, velocity-versus-load diagram, Figure 1, describes the relationship between an aircraftâs. speed, its longitudinal (pitch axis) maneuvering. capability, and its structural strength. The. positive-g, maximum lift line indicates how. aggressively, at any airspeed, we can apply aft.
Fairbanks, Alaska. During the early 19th century, some of the best scientific minds of the period believed that the aurora was caused by the reflection of sunlight from tiny ice crystals suspended high in the atmosphere.
Simply explained, these natural light displays in the sky occur in the Polar Regions and are caused by solar winds reacting with the Earthsâ magnetic field. Recently the Aurora Borealis have become more predictable in Iceland by new forecast methods developed by the Icelandic Meteorology Office.
