concerning the operation of aircraft in a Supercooled Large Droplet (SLD) environment aloft. The draft rule will require<br />
aircraft manufacturers to demonstrate that their aircraft can operate safely in an SLD environment for a period of time to<br />
facilitate a safe exit from the condition. It is anticipated that aircraft manufacturers will require a capability to demonstrate<br />
compliance with this rule via experimental means (icing tunnels or tankers) <strong>and</strong> by analytical means (ice prediction codes).<br />
Since existing icing research facilities <strong>and</strong> analytical codes were not developed to account for SLD conditions, current<br />
engineering tools are not adequate to support compliance activities in SLD conditions. Therefore, existing capabilities need<br />
to be augmented to include SLD conditions. In response to this need, <strong>NASA</strong> <strong>and</strong> its partners conceived a strategy or Roadmap<br />
for developing experimental <strong>and</strong> analytical SLD simulation tools. Following review <strong>and</strong> refinement by the airworthiness<br />
authorities <strong>and</strong> other international research partners, this technical strategy has been crystallized into a project plan to guide<br />
the SLD Engineering Tool Development effort. This paper will provide a brief overview of the latest version of the project<br />
plan <strong>and</strong> technical rationale, <strong>and</strong> provide a status of selected SLD Engineering Tool Development research tasks which are<br />
currently underway.<br />

The atmospheric environment surrounding the crash of American Airlines Flight 587 is investigated. Examined are<br />
evidence for any unusual atmospheric conditions <strong>and</strong> the potential for encounters with aircraft wake vortices. Computer<br />
simulations are carried out with two different vortex prediction models <strong>and</strong> a Large Eddy Simulation model. Wind models are<br />
proposed for studying aircraft <strong>and</strong> pilot response to the wake vortex encounter.<br />

Over the last five years, the Aircraft Icing Project of the <strong>NASA</strong> Aviation Safety Program has developed a number of<br />
in-flight icing education <strong>and</strong> training aids to support increased awareness for pilots of the hazards associated with atmospheric<br />
icing conditions. Through the development of this work, a number of new instructional design approaches <strong>and</strong> media delivery<br />
methods have been introduced to enhance the learning experience, exp<strong>and</strong> user interactivity <strong>and</strong> participation, <strong>and</strong>, hopefully,<br />
increase the learner retention rates. The goal of using these multimedia techniques is to increase the effectiveness of the<br />
training materials. This paper will describe the mutlimedia technology that has been introduced <strong>and</strong> give examples of how it<br />
was used.<br />

This thesis addresses the need of Naval Aviation Maintenance to streamline <strong>and</strong> more effectively manage the process of<br />
technical consultation aboard deployed aircraft carriers. The current process involves the physical transportation of an<br />
appropriate technician to the carrier to perform required maintenance <strong>and</strong>/or repairs. In light of the technology currently<br />
available this process becomes obviously obsolete, overly costly <strong>and</strong> needlessly time consuming. By implementing wireless<br />
technology in combination with advanced software allowing the virtual collaboration of parties widely separated by<br />
