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.
This rippling aurora was captured by photographer Don Rice in Fairbanks, Alaska. As presented here, it is intended for educational use only. The Geophysical Institute maintains a telephone aurora forecast at (907) 474-7558. Or check the Online Aurora Forecast - updated each day by 3 PM Alaska Time.
