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.
People generally know the aurora borealis by their common name, the Northern Lights. The northern lights are natural phenomena that occur in nature. Often on a clear, dark night in the boreal forest, green, purple, pink, and white lights dance on the horizon changing their shape and color. It is perhaps one of natureâ¢s most fascinating displays of artistry. Specifically, the aurora borealis is Latin for ï¬northern dawn.ï¬ The aurora australis is the same phemonena in the southern hemisphere, most visible from Antarctica, Australia, and New Zealand.
