Objective:� These two courses, together, provide the Capstone experience to the Systems Engineering undergraduate program.� It provides the students with the opportunity to put all of the course material that you have covered in the last 4 years into practice.� It also provides the faculty with the opportunity to test your ability to have assimilated the course material and certify that you are ready to receive the Bachelor of Science degree in Systems Engineering.� In addition to providing you the opportunity to utilize the systems engineering processes (e.g. requirements determination, work-breakdown structures, Pert Charts, test and evaluation, life cycle costing, etc.) it will require you to use your analytical skills in system modeling, simulation and decision making.� Emphasis in these courses will also be placed on written and verbal communication skill development and the creative process of engineering design.� You now have the basic skills that should allow you to create new systems that are technically sound, affordable, environmentally compatible and safe.� You will be asked to determine whether a Business Case exits for your designs in the Program Proposal that you will submit in late November.� You will be required to manage a complex, unstructured project using the management and teamwork skills that you have developed.� The class will be divided into four project teams, each working on a real transportation problem.�� Each student MUST maintain a personal log of all design activity, to be inspected upon demand.� You MUST submit a weekly time sheet to your team timekeeper to be submitted at all major program reviews.� All teams will be entered into inter-scholastic senior design competitions at the end of the Spring Semester.� GMU has a history of doing very well in these competitions; I expect the same or better from you.
As noted by Norm Augustine, aerospace system developments led to much of what we use in systems engineering today and are a good surrogate for almost all large-scale, complex systems.� All projects this year are aerospace related and are used for: 1) The public availability of relevant data and complex simulation models; 2) Government/industrial sponsor interest and relationships with the SEOR department; 3) Related sponsored research in the department; 4) The availability of related system domain knowledge courses in the department (i.e. SYST 460/560).

Project: Design an automated airway system for a UAV cargo concept. Federal Aviation Administration Office of Aviation Research, 800 Independence Ave. Washington DC
A concept of an airport-independent uninhabited air vehicle (UAV) cargo system has been suggested as one way to off-load cargo traffic from airports to save that capacity for passenger transports as well as to provide more efficient origin to destination cargo delivery.�� The concept is for cargo UAVs to operate from an industrial park where the cargo originates to another destination industrial park.�� For such a system to operate safely in the national airspace system (NAS), a new automated air traffic management (ATM) system is needed that supports operations to and from many locations around a metropolitan area.�� The system should provide airways that are separate from normal air traffic controlled (ATC) aircraft and are as efficient for the UAVs as possible.� The design problem includes how the UAV airway system interacts with normal ATC.�� It can be assumed that once a UAV airway is defined, ATC will honor it as dedicated 4-D airspace.� The airways should also be flexible to allow for weather conditions.�� Finally it can be assumed that the UAVs would be turboprop aircraft and optimized for this type of operation.�� This design problem is only to consider the cruise portion of flight.� Take-off, landing, and associated sequencing of aircraft will be addressed later.�� A paper on the airport-independent UAV cargo system concept will be provided as background by the Team Advisor.

B.� Design Project : Support to Raytheon�s Terminal Area
Capacity Enhancement Concept (TACEC) activity. �Raytheon Command, Control, Communications and
Information Systems,
As part of Raytheon�s Space Act Agreement support to the NASA AMES VAMS Program we are developing a future ATM concept focused on the Terminal and Surface domains. Our initial investigations led us to the fact that significantly increased capacity (2x+) in the terminal area can only be gained by;
1.) Meeting the wake vortex avoidance requirement by a different approach than in-trail separation.
2.) Adding more runways
Our concept achieves these goals by using the �Flight Corridor� approach to Wake Vortex (WV) avoidance combined with very closely spaced parallel approaches in all weather to provide the additional runways required.
Flight Corridors (based on initial work by Vern Rossow, NASA) are spatial regions �behind� aircraft which are wake hazard free. Like all WV spatial descriptions there is uncertainty in the actual boundaries of these corridors. This uncertainty increases as time (or distance behind the aircraft) grows. The closer two aircraft are together the more certain wake free regions are known. Wake vortex avoidance is achieved by flying aircraft closer together, not by in-trail spacing.
This closely spaced parallel flight formation naturally leads to the use of closely spaced parallel approaches. The benefits of CSPA�s are well documented, and the challenge of IFR operation well studied. Raytheon believes the technologies needed for VFR operation in IFR conditions will exist in 2020, and runway spacings of 750ft can become the norm. This translates into the kind of runway increases we need to double the NAS capacity, by greater utilization of today�s runways or by actually building new runways �between� existing ones.
Figures 1 & 2 illustrate the Flight Corridor and Parallel Approach concepts.
Suggested Task Descriptions for GMU involvement
1. Key to closely spaced parallel approaches is the �Blunder� factor. Any parallel flight operation must account for errors in flight paths and the consequential reactions. GMU could support Raytheon�s analysis of these errors including;
� Flight technical error � what are the characteristics of future (2020 vintage) aircraft flight controls and the nature of their likely errors? (Boeing could supply FTE simulation model)
� Avoidance maneuvers � what are possible reactions required of aircraft when blunders do occur? (possible cooperation with Cockpit Resource Management Research in the PSYCH dept.)
� Operational Concept definition � roles and responsibilities of AT manager and� flight crews for CSPA operation.
2. Infrastructure to support TACEC operations involves not only the procedural implementation but also the airport facilities to accommodate the increased traffic loads. GMU analysis of alternative airport layouts to best support parallel arrival and departures, gate configurations, passenger accommodations would be helpful. (would require either TAAM simulation or ARENA simulation model development).
3. Wake Vortex avoidance in TACEC requires similar performing aircraft on final approach to insure they maintain position in the required formation. Sequencing aircraft from arrival into the terminal airspace to the start of CSPA requires prescribed flight profiles that must be flown precisely such that the aircraft arrive at the final fix at the correct time. We envision this as an automated flight management system operation with profiles up-linked to the aircraft continuously. These flight profiles must dynamically deal with conflict avoidance, weather, emergencies, etc. Can GMU support Raytheon in generation of algorithms, process, or analysis of these dynamic flight profiles? (could involve work with either Boeing and/or Aurora).
4. Although TACEC deals with Wake Vortex avoidance by operating aircraft close together this does not eliminate the need to impose in-trail spacing on those aircraft arriving on the next �wave.� Support to Raytheon�s concept evaluation is required to analyze the total capacity increase for the National Airspace System, hence total traffic flow analysis must be developed that combines CSPA with appropriate arrival rates for WV avoidance as well as departure flows.

�Design Project:
Asset Tracking Study for Sensis Corporation, 5793 Widewaters Parkway, DeWitt, NY 13214, 315-445-5711
The proposed Senior
Student Project is a study of the operational benefits to the airlines of an
asset tracking system for airline ground vehicles.� This study would investigate the possible
ways an asset tracking system could be designed and the benefits that could be
derived by different system features.
The first task is to
totally understand and analyze the current systems of airline ground vehicle
command, communications and control (C3). Deicing vehicles, fueling
trucks, tugs, baggage carts, food and water supply vehicles, are all examples
of ground operations that require coordinated C3.� The responsibilities of ramp tower
controllers and ground crews along with the current technology should be
understood and explained.
The second task is to
determine how an asset tracking system could be used to improve C3.� The operational benefits, such as improved
service and greater efficiency, need to be quantified.
The study should also
indicate the importance of different features of such a system.� The study would include as a minimum, the
operational benefit of the following capabilities:
-
Operational benefits of continuous asset
location tracking versus updates at key operational milestones.
-
Operational benefits of location accuracy
(is ramp area or communications cell sufficient accuracy or is GPS accuracy
needed)
-
Operational benefits accrued from asset
tracking broken down by the types of vehicles.
-
Operational benefits of an interactive datalink structure in which ground personnel input updates
and milestones into the system, versus a system that
is strictly surveillance.� This analysis
should again be broken down by vehicle type.
-
Off-line modes in which the system could
be used to perform post-mortem analysis of operations and features desirable to
aid in this capability.
An airline partner
will also need to be recruited. The operations analyzed should be at a hub
airport for the partner airline.� FedEx
