What does "Time in Your Tanks" mean? Depending upon your aircraft's particular fuel consumption rate, the amount of usable fuel in your aircraft equates directly to how long your aircraft will fly. The longer you can fly, the more choices you have for ensuring a safe flight. This article provides some general tips on determining and managing the "t

Prepared ca. 1995. The Line Integral Convolution (LIC) method, which blurs white noise textures along a vector field, is an effective way to visualize overall flow patterns in a 2D domain [Cabral & Leedom '93]. The method produces a flow texture image based on the input velocity field defined in the domain. Because of the nature of the algorithm, t

The specter of fire in the air is a pilot's recurrent nightmare. Each fire is different and its gases could be toxic. When carbon dioxide levels increase and oxygen concentrations decrease. However, not all symptoms will necessarily be experienced. Knowledge of the less obvious hazards and a few simple preparations can increase one's chances.
This paper summarizes some of the results of a three-year project that was undertaken by the Research and Special Programs Administration's Volpe National Transportation Systems Center (Volpe Center) to: (a) identify crash causal factors and applicable intelligent transportation systems (ITS) countermeasures; (b) model crash scenarios, and avoidanc
