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.
Aurora Borealis are more common in northern latitudes, such as the northern states or Canada. Iceland and Scandinavia see them frequently as well. The cause is a stream of â¦ high-energy electrically charged particles from the Sun, often emitted during a solar flare or coronal mass ejection (CME).
