     DETAILED DESCRIPTION 
       [0036]    As set forth above,  FIG. 1  is a simplified flow diagram showing a method associated with the communication and evaluation of an equipment upgrade proposal. The steps shown in  FIG. 1  can be taken substantially at the beginning of a sales process, a process that can culminate in the sale of products and/or services or can culminate in the rejection of the equipment upgrade proposal. These steps are enhanced relative to what is currently done and can increase the likelihood of a sale. 
         [0037]    The program starts at step  10 . At step  12 , the seller can deliver a program to the potential customer. The program can be delivered by first placing or encoding the program on computer-readable medium of a transferable storage device and then transferring the storage device to the potential customer. The storage device can be a CD or a memory card or an accessory drive or any other form of storage device.  FIG. 2  shows an exemplary accessory drive  14  that can carry the program. Alternatively, the program can be communicated to the seller electronically, such as by email. Alternatively, the program can be made accessible to the potential customer through a network such as the internet. 
         [0038]    An exemplary embodiment of a program that can be delivered to a potential customer will be described in greater detail below. However, generally, the program can accomplish several things. First, the program can have the capacity to receive input from the potential customer. For example, the program can solicit and receive data relating to how the potential customer currently operates its equipment. This opportunity to enter data allows the customer to test the equipment upgrade proposal under various scenarios to determine the set of circumstances under which the equipment upgrade proposal is most desirable. 
         [0039]    Second, the program can generate video sequences that relate to the equipment upgrade proposal, but are not necessary for assessing the economic desirability of the equipment upgrade proposal. For example, the program can generate a beginning or opening video sequence prior to the input of data that shows the equipment in operation. The video sequence can include images particularly associated with the potential customer, such as an overhead view of the potential customer&#39;s facility. Sounds associated with the potential customer and the equipment can be emitted during the video. Such a video and sounds sequence can be an enjoyable experience for the potential customer, an experience that induces the potential customer to be more comfortable with the program and also to more frequently execute the program. 
         [0040]    Third, the program can generate video sequences that relate to the specific technical nature of the upgrade. For example, if the upgrade involves replacing components of an engine, the program can be operable to generate a video sequence that takes the viewer through the internal structures of the engine. The video sequence can show the viewer the specific technical nature of the upgrades. 
         [0041]    Fourth, the program can generate output in a side-by-side comparison of operating conditions for the equipment. One side of the comparison can display current operating conditions and the other side can display the improvements that could be enjoyed if the equipment upgrade proposal is accepted. For example, the program could generate a split screen showing gauges of the equipment on both sides. On a first side, the gauges could display values corresponding to current operating performance. On a second side, the gauges could display values corresponding to operating performance if the equipment upgrade proposal is accepted. The gauges displayed on the monitor screen can appear identical to gauges on the equipment. 
         [0042]    Fifth, the program can generate an output display of economic data, such as payback period. The program can include stored data and, in combination with the potential customer&#39;s input data, can execute mathematical operations to generate graphs, tables, or any other form of presentation that shows cost, payback period, or other data. The term “payback period” in business and economics refers to the period of time required for the return on an investment to equal the sum of the original investment. Payback period can be particularly relevant in situations in which a piece of equipment can be upgraded or allowed to continue operating at an existing level of efficiency and/or output. 
         [0043]    The capabilities of the program set forth above can be arranged in a particular order to increase the likelihood that the equipment upgrade proposal will be accepted. An initial video sequence that relates to the equipment upgrade proposal, but is not necessary for assessing the economic desirability of the equipment upgrade proposal, can occur first so that the potential customer is drawn to the program, but not overwhelmed with rigorous intellectual demands. Next, a video sequence can occur that takes the viewer through the internal structures of the engine. The video sequence can show the viewer the specific technical nature of the upgrades. This second event in the program, like the first, need not overwhelm the potential customer with rigorous intellectual demands. However, the second event can be more informative than the first event. Thus, the potential customer&#39;s attention is being increasingly focused on the equipment upgrade proposal. A third event occurring in the program can be a screen soliciting data from the potential customer. The amount of data or the number of data categories for data input can be selected based on the nature of the equipment, the nature of the upgrades, or any other consideration. A fourth event occurring in the program can be a split screen with gauges displaying values corresponding to current operating performance and gauges displaying values corresponding to the operating performance that could be enjoyed if the equipment upgrade proposal is accepted. Thus, the potential customer can be shown how the upgrade could improve efficiency/output/power during run time of the equipment. These benefits would be the immediate benefits enjoyed by accepting the equipment upgrade proposal. A fifth event occurring in the program can be display output of economic data, such as payback period. Thus, after viewing immediate benefits, the potential customer can be provided with a long term view of the benefits that could be enjoyed by accepting the equipment upgrade proposal. It is noted that the order of events set forth above is an example and that other arrangements (events and order of events) can be applied. 
         [0044]    At step  16 , the potential seller can operate the program independently of the seller. The method illustrated by  FIG. 1  can allow the potential customer to evaluate the equipment upgrade proposal from various perspectives without well-meaning but undesirable interference from the seller. The potential customer can test the equipment upgrade proposal under various scenarios to determine the set of circumstances under which the equipment upgrade proposal is most desirable. The method can allow the potential customer to evaluate the equipment upgrade proposal at his or her leisure. The process can end at step  18 . A possible additional step subsequent to step  18  could be the potential customer&#39;s acceptance of the equipment upgrade proposal. 
         [0045]    An exemplary equipment upgrade proposal and program will now be described. It is noted that this description may be a disclosure of one or more inventions. This provisional patent application discloses what has been developed and does not expressly or implicitly assert that only one invention is disclosed or that the example below is the only way of practicing any invention that is disclosed herein. 
         [0046]    An exemplary equipment upgrade proposal can relate to the upgrade of turbine engines for operating aircraft, such as the C-130. Each C-130 includes four turbine engines. An exemplary upgrade of these turbine engines can be to replace various components of the turbine engine. The replacement of these components can result in improvements (declines) in turbine inlet temperature and fuel consumption. 
         [0047]    The seller of the equipment upgrade proposal can transfer a copy of an executable program to a potential customer. When the exemplary program is carried out on a computer, a video can be displayed on the monitor associated with the computer and sounds associated with the video can be emitted from speakers associated with the computer. The exemplary video can initially show the Earth and progressively narrow focus to the geographic location of the potential customer. The focus can further narrow on a C-130 aircraft taxiing on a runway. The aircraft can be shown with colors, indicia, flags, or any other visual symbol associated with the potential customer.  FIGS. 3-8  show a progression of images that can be shown during the first video sequence of the exemplary program. During the video, sounds such as a national anthem can be emitted from the speakers as the viewpoint narrows focus from the Earth to the aircraft. The sounds of the aircraft can also be emitted. This combination of video and sound can resonate with the potential customer and promote the potential customer&#39;s interest in continuing the operation of the program. Also, the first sequence of video and sound requires no rigorous intellectual demands of the viewer. The visual and auditory information is experienced and the viewer is not required to make a decision, obtain data for input, or remember details of what is being presented. 
         [0048]    Next, a second video and sound sequence can be emitted by the computer under the direction of the program. The second sequence can take the potential customer through the internal structures of the turbine engine. At various locations where upgrades will occur, the video sequence can hold passage through the engine and momentarily focus on the specific internal structures that will be upgraded. This second event in the program can be more informative that the first, but need not overwhelm the potential customer with a high level of detail about the structural upgrades.  FIGS. 9-16  show a progression of aft-viewing images that can be shown during the second event of the exemplary program.  FIG. 9  is a view looking into a turbine engine.  FIG. 10  is a view downstream of the inlet of the turbine engine and upstream of the compressor section.  FIG. 11  is a view immediately upstream of the compressor section.  FIG. 12  is a view in the compressor section.  FIG. 13  is a view at an exit of the compressor section, showing the dome panel downstream.  FIG. 14  is a view downstream of the compressor section and upstream of the dome panel.  FIG. 15  is a view at an aft end of a combustor section, showing the turbine section downstream.  FIG. 16  is a view at an exit of the turbine section. 
         [0049]    The executable program can then query the potential customer for data input. The computer running the program can thus receive input related to the nature of use of current equipment.  FIG. 17  shows a display screen according to the exemplary program for soliciting data and receiving input. The amount of data or the number of variables solicited from the potential customer can vary as desired. The data corresponds to how the potential customer currently operates its equipment. This opportunity to enter data allows the customer to test the equipment upgrade proposal under various scenarios to determine the set of circumstances under which the equipment upgrade proposal is most desirable. Embodiments of the invention can accommodate an unlimited number of clients. A client screen can be included that dynamically paginates to account for all clients in each application. 
         [0050]    Referring now to  FIG. 17 , the exemplary program solicits the number of aircraft in the fleet of the potential customer. This information is useful in determining the overall cost of the upgrade as well as the payback period. The exemplary program also solicits the ratio between spare engines and installed engines. Generally, the operator will desire to keep aircraft flying at all times, so upgrades can be applied to spare engines first or, alternatively, installed engines will be swapped with spare engines and then upgraded. The percentage of spare engines relates to the time period required to complete the upgrade and therefore relates to payback period. 
         [0051]    The exemplary program also solicits average flight hours per year. This information is useful for determining payback period. The greater the flight hours per year, the sooner payback of the upgrade can be enjoyed. The exemplary program also solicits the “Current T56 Engine Fleet MTBR.” The term “T56” is a reference to the turbine engine to be upgraded in the exemplary equipment upgrade proposal. MTBR is an acronym for mean time between removal. This value relates to how many hours of operation pass before the turbine engine is removed and overhauled. The need to overhaul is determined by visual inspection of various parts of the turbine engine. This value reflects how hard the engine is being pushed. The engine may be operating in a harsh environment or the engine may be regularly pushed to its operational limit by the potential customer. This information is useful in determining payback period. 
         [0052]    The exemplary program also queries the potential customer: Include Turbine Life Improvement from 3.5 Lower Turbine Inlet Temperature Cruise Ops in Payback Cal? The number 3.5 refers to the designation of the upgraded turbine engine configuration. This query is asking the potential customer if it will choose to apply the upgrade to increase the life of the equipment or if it will apply the upgrade to increase the performance of the equipment to operate. This information is useful in determining payback period. 
         [0053]    The exemplary program also solicits the cost of fuel, the start date of the upgrade implementation, the forecast retirement date of the fleet, and the number of engines that will be upgraded each year. This information is useful in determining payback period. The final category of information is the current rate of series 3 shop visits per year. The term “series 3” refers to the designation of the current turbine engine configuration. The current rate of “series 3” shop visits can be calculated by the program based on the information input in the fields described above. The calculated number can be noted and confirmed by the potential customer. 
         [0054]    Embodiments of the invention can allow a potential customer to vary yearly data, such as Fuel Cost, Fuel Burn Delta, etc. This data can be updated by the customer without taking the application back into programming year after year. 
         [0055]    The program can also include predetermined or assumed data. This data in the exemplary program will be discussed in greater detail below. The data input by the potential customer and the assumed data can be subjected to algorithms by the program to generate two forms of output. A first form of output can be real-time data showing how engine operating conditions will improve upon completion of the upgrade. The exemplary program can cause the monitor to display a side-by-side comparison of gauges. In  FIG. 18 , the gauges to the left are similar to gauges in the aircraft and display information corresponding to the current (non-upgraded) engine. A temperature gauge measuring turbine inlet temperature and a fuel flow gauge are the largest gauges. To the right of the screen, similar gauges are shown displaying information corresponding to the upgraded engine. Gauges displaying values for air speed, altitude and torque can be the same on both the left and right side. The gauges can be dynamic, showing at least one measurement of a dimension, quantity, or mechanical accuracy of the current equipment during run time and a second gauge shows the at least one measurement of a dimension, quantity, or mechanical accuracy of upgraded equipment during run time. 
         [0056]      FIGS. 18-21  also show that the screen displays a graph correlating the operating conditions of both upgraded and non-upgraded engines at various stages of operation. In the bottom right corner, a generally red line of multiple segments represents a flight path of the aircraft. The left oblique segment represents the climbing portion of the flight path. The center horizontal segment represents the cruising altitude portion of the flight path. The right oblique segment represents the descending portion of the flight path. The multi-segment line is white where the position along the flight path correlates with the operating conditions displayed by the gauges. 
         [0057]    A second form of output of the exemplary program can be economic data, such as payback period. Thus, after viewing immediate benefits, the potential customer can be provided with a long term view of the benefits of accepting the equipment upgrade proposal.  FIGS. 22 and 23  show a graph that can be displayed by a monitor under the control of the executable program. Each point along the line can provide specific data related to payback.  FIG. 22  indicates that the maximum level of investment will be achieved in the fourth year of the exemplary upgrade.  FIGS. 22 and 23  indicate that payback will occur in the seventh year of the exemplary upgrade. In  FIGS. 22 and 23 , the y-axis shown in the graphs can be predetermined or fixed, or can be dynamic. Changing the scale of the y-axis in response to data entered by a customer allows for a more dramatic payback curve. 
         [0058]    The display of  FIG. 23  includes a tab marked “Performance Impact,” which relates to aircraft performance.  FIG. 24  shows the displayed screen when this tab is selected. Assumptions for all aircraft and engine parameters that will affect aircraft performance are displayed in this screen. In the upper right-hand corner, a pull down menu is accessible by the potential customer to obtain further data output. The first option on the pull down menu is the Estimated Ground Rules, which are shown in  FIG. 24 . A second option from the pull down menu can be Estimated Payload Range, as shown in  FIG. 25 . In  FIG. 25 , the white represents the current payload range. The green and dashed line represents the improved payload range with decreased turbine inlet temperature. Operating along this line, the operator will enjoy improved payload capacity while also enjoying reduced turbine inlet temperature. The solid green line represents an optional improved payload range without decreased turbine inlet temperature. Operating along this line, the operator will enjoy even larger payload capacity, at the expense of the turbine inlet temperature remaining at current levels. In other words, the solid green line represents applying the upgrades to maximize performance at the expense of time interval between removal. 
         [0059]    A third option from the pull down menu can display the Estimated Cruise Ceiling over various gross weights, as shown in  FIG. 26 . A fourth option from the pull down menu can display the Estimated Climb Profile over various times and distances, as shown in  FIG. 27 . A fifth option from the pull down menu can display the Estimated Range at a specific altitude, as shown in  FIG. 28 . The lines in FIG.  26 —(white, dash green and solid green) are analogous to the lines in  FIG. 25 . Other options can be provided by the executable program. 
         [0060]    The executable program described above can be provided to a potential customer for evaluation of an equipment upgrade proposal. The executable program includes theatrical elements as well as economic tools that are both tailored to the potential customer. The exemplary embodiment of the invention is superior to one-way, 2-Dimensional pitch presentations. These presentations do not provide the opportunity for instant, dynamic or customer-unique data, interaction or personalized feedback. 
         [0061]    The exemplary embodiment of the broader invention can be constructed using Adobe&#39;s Flash CS3 platform and the coding language Actionscript 2.0. The primary component for application development can be Adobe Flash Framework and Actionscript Coding Language. Other technologies that could be potentially used, such as Adobe Flex, AIR, or any other software built in the Adobe SWF specification; Adobe Director and Lingo coding language, Microsoft Silverlight; Web-based or application-based coding language such as JAVA, JavaFX, Microsoft.NET, AJAX, Javascript, PHP, ColdFusion, RoR, Suneido. 
         [0062]    The financial payback calculation can be created with Microsoft Excel. Other technologies could be used. The payback formula applied in the program can be translated into Actionscript code to allow a graphical output of results, as well as printable html forms of customer data. 
         [0063]    Three-dimensional images such as aircraft can be created using Autodesk Maya. Other technologies could be used, such as Autodesk applications, 3D Studio Max, Lightwave, Cinema 3D, custom-built/proprietary 3D modeling and animation applications, UniGraphics, and CAD software. 
         [0064]    Animated satellite imagery can be created using Google Earth Pro. Other technologies could be used, such as Microsoft&#39;s Virtual Earth 3D, ArcGIS Explorer, DigitalGlobe, animated satellite imaging systems. 
         [0065]    As set forth above, a plurality of different screen displays can be generated during operation of the program, including at least one screen display during the step of receiving customer input and at least one screen display during the step of displaying payback data to the customer. In the exemplary embodiment of the invention, at least one of the plurality of different screen shots are customized based on information associated with the potential customer other than the input related to the nature of use of current equipment. 
         [0066]    One or more screen displays can be customized by showing the equipment to be upgrade in a particular operating environment and/or in operation. The equipment to be upgraded could be used in several different planes. Embodiments of the invention can be practiced where a potential customer is given access to a program that generates at least one screen display of the particular model of plane used/maintained by that potential customer. In the exemplary embodiment, the turbine engine to be upgraded can be shown mounted on an aircraft. 
         [0067]    Embodiments of the invention can be practiced where a potential customer is given access to a program that generates a series of screen displays defining a video of the equipment in operation. The video can be generally unnecessary to the equipment upgrade proposal. In the exemplary embodiment, the video of the engines in the operating environment of the C-130 and operating by turning a propeller is generally not necessary for potential customer to evaluate the equipment upgrade proposal. However, video that is generally unnecessary can be desirable in that the video can stimulate the potential customer&#39;s interest in completing the program. 
         [0068]    Alternatively, the video can be generally relevant to the equipment upgrade proposal. In the exemplary embodiment, the video in which the viewer passes through the engine can help explain the nature of the upgrades. Several of the individual screen displays are views internal or hidden of the equipment. The video can clarify to the potential customer the nature of the technical upgrades being proposed. 
         [0069]    The exemplary embodiment can entertain a viewer of the plurality of screen displays with one or more screen displays that are unnecessary for the receiving, estimating and displaying steps. To entertain is to hold the attention of pleasantly or agreeably, to amuse. The beginning video sequences in which the potential customer&#39;s geographic location is the focus of a zoom, the equipment is shown operating in the potential customer&#39;s planes, and the planes are shown in flight are examples of first screen displays for entertainment for the potential customer. These video sequences are not required for the program to provide a payback period. In the exemplary embodiment, these video sequences can be viewed by the potential customer without requiring critical thinking on the part of the potential customer. 
         [0070]    The exemplary embodiment also provides “second” screen displays that educate the potential customer. The video sequences that travel through the engine can educate the potential customer on the general technical nature of the upgrades being proposed. 
         [0071]    A screen display can be “unnecessary” if it contains images, text, indicia, or any other viewable aspect that is not required for receiving input from the customer, for estimating the payback period, or for displaying details of the payback period to the customer. In embodiments of the invention, none of the viewable aspects on a particular screen display may be unnecessary for receiving, estimating and displaying. For example, in the exemplary embodiment, the screen displays in which the potential customer&#39;s location is the subject of a zoom are not necessary for receiving input, estimating payback, and displaying data associated with payback. In other embodiments, a portion of a particular screen display may be unnecessary for receiving, estimating and displaying. For example, in the exemplary embodiment, the image/video of the aircraft at the bottom-right corner in  FIGS. 18-21  is not necessary for receiving input, estimating payback, and displaying data associated with payback whereas the gauge displays could be necessary to help the potential customer understand the full extent of upgrade performance and payback. In still other embodiments, none of the viewable aspects on a first screen display may be unnecessary for receiving, estimating and displaying and a portion of a second screen display may be unnecessary for receiving, estimating and displaying. For example, in the exemplary embodiment, all the viewable aspects in  FIGS. 22-28  relate to displaying payback data. The necessity of a particular viewable aspect of a screen display or of an entire screen display can be assessed based on the functionality of the viewable aspect in displaying numerical data related to payback. For example, the viewable aspects in  FIG. 28  are not all numerical data (tabs, text, lines, buttons). However, these viewable aspects facilitate an orderly presentation of the numerical data.
