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.
Where can you see the aurora borealis? The aurora borealis is normally only visible from within 20 degrees of latitude of the North Pole. In North America, most viewing opportunities are limited to those in Alaska or the extreme northern parts of Canada. However, solar flares and geomagnetic activity can vastly increase the size of the aurora borealis, making its lights much more active and visible to much of the United States.
