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.
For those who live in Alaska, the Aurora is a part of northern life. Fall, winter and spring is the special season for viewing the great lights for residents and off-season visitors. Some Alaskans have Aurora Alerts; when a display begins, the first person to spot them begins a phone tree to get the word out.
