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.
The University of Alaska is but one of many facilities where research still continues into the phenomenon, but so far, research seems to indicate that the aurora is caused by radiation emitted as light from atoms in the upper atmosphere as they are hit by fast-moving electrons and protons.
