    As Aircraft Solutions takes the next step in its growth, it is imperative that its IT infrastructure keep pace as to not counteract gains made by the company during this expansion. This is especially important given it designs and fabricates components for both commercial and defense related industry. Given the increase in staff as well as outside vendors accessing the network, a more centralized approach to antivirus protection has to be adopted. It is equally important that certain elements within the network that have been done manually, such as Access Control List policy, be automated to avoid consuming the IT department in an ever escalating bar of employee hours.…

    For this exercise, the procedures we followed were to initially find out the V1, Vr and the Balanced Field Length for the aircraft. By working as a crew we reviewed the flight profile to see what the flight procedure would be to understand how to determine the speeds for the aircraft. Each crew member had a different role in completing the exercise. One crew member flew the aircraft on the program making airplane inputs; another was reading the directions on the flight profile directing the one flying. We paused the profile any and every time we had a question or found a result; jotting it in our books to gather the results.…

    One of the requirements for this course is an Aircraft Performance Research Project that entails planning a flight from Denver International Airport (KDEN) to Chicago O'Hare International Airport (KORD) for a given aircraft, weather conditions, and assumptions. The objective is to apply what has been learned throughout this course. Drawing on aeronautics theory and using the performance charts and equations presented in the course, each student is to answer a sequence of questions that step through the planning process. Remember, as with all of the exercises, all work (calculations) must be shown as much as possible. After all of the questions have been answered, the next task is to create a two-dimensional representation of the flight path showing the airspeeds, distance, fuel burned, and fuel remaining for the Takeoff, Climb, Cruise, Descent, and Approach phases of the flight.…

    * The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me better understand the actual design of an actual airplane in some ways.…
