GOVERNMENT LICENSE RIGHTS 
   The U.S. Government may have certain rights in the present invention as provided for by the terms of Contract No. NAS1-00107 awarded by the NASA Langley Research Center. The invention described herein was made in the performance of work under NASA Contract No. NAS1-00107 and is subject to the provisions of Section 305 of the National Aeronautics and Space Act of 1958 (42 U.S.C. 2457). 

   TECHNICAL FIELD  
   The present invention relates generally to the display of information and in particular to the display of avionic information via multiple miniature displays. 
   BACKGROUND  
   Current avionic displays are typically designed to display different sets of information either on separate displays or only one set of information at a time. This is required because the displays typically display different information in a similar way. For example, both threatening terrain regions and severe weather are typically illustrated with color regions on a display screen. Moreover, it is common for terrain and weather information to be displayed using similar color palettes. For example, both terrain and weather radar may be displayed using the same colors red, yellow and green to represent increasing degrees of threat, safety criticality, or need for flight crew awareness or response. Red is typically designated as indicating either the most severe weather or the most critical terrain relating to the position of the aircraft. The green color is typically designated as indicating the least severe weather or the least critical terrain relating to the current position of the aircraft. Moreover, the yellow color is typically designated as indicating weather that has a severity level somewhere between the severity level designated by the red and green colors and a terrain that is in between the terrain indicated by the red and green colors in relation to the position of the plane. 
   To avoid confusion in displaying weather and terrain information, separate displays are used or the information is toggled between screens of the same display. However, there are limitations to this implementation. For example, with separate screens, the pilot must be able to integrate the weather and terrain information mentally in order to avoid conflicts. This takes time and can be confusing especially when the screens may provide the information in different size grids (scale) or orientation. Moreover, in critical situations the use of different screen or toggling between screens is detrimental in conveying the needed information is a fast an effective manner. 
   For the reasons stated above and for other reasons stated below which will become apparent to those skilled in the art upon reading and understanding the present specification, there is a need in the art for a method of conveying different information simultaneously in an efficient and effective manner on a single display screen. 
   SUMMARY OF INVENTION  
   The above-mentioned problems of current systems are addressed by embodiments of the present invention and will be understood by reading and studying the following specification. 
   In one embodiment, an avionic display screen is provided. The aviation display screen includes a main window and a plurality of miniature windows. The main window is adapted to illustrate one set or class of information. Each miniature window is adapted to display one set or class of avionic information.

   DETAILED DESCRIPTION  
   In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the inventions may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that logical, mechanical and electrical changes may be made without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the claims and equivalents thereof. 
   Embodiments of the present invention provide a display that effectively conveys different sets of information on a single display screen. In particular, in one embodiment, a large window along with smaller windows (multiple miniatures) are used to display more than one set of information. Each of thee miniatures shows a scaled down version of information overlaying the same area location fill (or background) displayed in the larger window. This allows for more than one set of information to be shown on a display screen at the same time in a non-confusing manner. 
   Referring to  FIG. 1 , a display screen  100  of one embodiment of the present invention is illustrated. As illustrated, the display screen  100  includes area fill  102 . The area fill  102  is a background of non-threatening terrain which is illustrated in the large window  101  and the smaller windows (miniature windows)  104 ,  106  and  108 . The area fill  102  is typically illustrated with the used of neutral colors or no color at all. Moreover, the area fill  102  can also be generally referred to the situation awareness terrain  102 . Each miniature window  104 ,  106  and  108  illustrates a specific set of information. In the embodiment of  FIG. 1 , miniature window  104  illustrates traffic  112 . Miniature window  106  illustrates weather regions  114 - 1  through  114 - 2 . The weather regions  114 - 1  and  114 - 2  are distinguished from each other by color. In this illustration, only two different colors are present, designated generally as  114 - 1  and  114 - 2 . This indicates two different levels of severity of the weather  114 - 1  and  114 - 2  in a specific location. It is understood that a different numbers of colors and severity levels may appear and that this invention is not limited in number and severity classifications. 
   Miniature window  108  illustrates terrain regions which are generally designated as  116 - 1  and  116 - 2 . The terrain regions  116 - 1  and  116 - 2  are used to display terrain having a level of concern. These regions are also distinguished from each other by color. In this illustration, only two different colors are present, designated generally as  116 - 1  and  116 - 2 . This indicates two different levels of concern of the terrain  116 - 1  and  116 - 2  in a specific location. It is understood that different numbers of colors and concern levels may appear and that this invention is not limited in number and severity classification. 
   In embodiments of the present invention, the information in the miniature windows  104 ,  106  and  108  can be displayed in the large window  101  upon selection by the operator. The large window  101  can also be referred to as the main window  101 . For example, in the embodiment of  FIG. 1 , the weather has been selected to be viewed in the large window  101 . In one embodiment, the selection of the set of information to be displayed in the large window  101  is accomplished by depressing an activation button. For example, referring to  FIG. 1 , the terrain regions  116 - 1  through  116 - 2  is illustrated in the large window  101  by depressing activation switch  120 . The weather areas  114 - 1  through  114 - 2  are illustrated in the large window by depressing activation switch  122 . Moreover, the traffic  112  is illustrated in the large window  101  by depressing activation switch  124 . 
   In embodiments of the present invention, the multiple miniature windows  104 ,  106  and  108  each display only one type of information which can be displayed in the large window one at a time. The multiple (or plurality of miniatures) provide a preview of what information exists. This layout presents the different information in one display screen in a non-confusing manner. Moreover, this multiple miniature invention allows for both terrain and weather information to be displayed using the standard green-yellow-red scheme that pilots are used to without confusing the pilot&#39;s understanding of which hazard type is being displayed. Using the multiple miniatures of the present invention, a pilot can choose to view weather in the main window, but still has information about terrain and traffic relative to his or her position. This reduces clutter on the main display screen  100  because only one hazard is presented but also allows the opportunity to maintain situational awareness via the miniature preview screens  104 ,  106  and  108 . In addition, spatial parallelism makes it easier for pilots to integrate information from multiple displays. Moreover, it will be understood that the number of miniature windows will vary according to the number of sets of information provided and that this invention is not limited to three miniature windows. 
   In embodiments of the present invention, the miniature windows  104 ,  106  and  108  are adjacent the main display (or window)  101  and the proportions are held constant to allow integration of information across displays. The orientations of the miniature windows  104 ,  106  and  108  in relation to the main window  101  can vary in position. For example, the miniature windows  104 ,  106  and  108  can be positioned on the top, right side, left side or bottom of the main window  101 . Moreover, in one embodiment, if a pilot zooms in/out on the main display  101 , the miniatures  104 ,  106 ,  108  are adapted to also zoom in/out by the same factor. In contrast, when using present displays, a pilot must hold information from one display in his or her memory while switching to a new information display thereby increasing the difficulty of comparing the locations of two hazard types on the map. In one embodiment, varying ranges between multiple miniatures and the main display are used. For example, in one embodiment, a TACS range is 10 nm, a weather range is 50 nm and a terrain range is 25 nm. In further embodiments, the ranges are either manually and individually changed or automatically and algorithmically changed according to the crew task (e.g., avoid tactical traffic, adjust range of TCAS) or the range of important information. Further in another embodiment, when a hazard is detected in the information displayed in one of the miniature windows  104 ,  106  and  108 , that information is automatically toggled to the large window  101  to get the pilots attention. 
   Referring to  FIG. 2 , a flow diagram  200  of one embodiment of the present invention is illustrated. As illustrated the fill area over a given location is determined and displayed in both the main window and the miniature windows ( 102 ). The traffic information is then determined and displayed in a first miniature window ( 104 ). The weather is determined and displayed in a second miniature window ( 106 ). The terrain is also determined and displayed in the third miniature window ( 108 ). Activation switches are then monitored to determine if it is desired to change the information displayed in the main window ( 112 ). Any type of switch or the like that creates a change signal can be used to indicate a desired change in the information illustrated in the main window. For example,  FIG. 1  illustrates buttons that are depressed to create a change signal. In other embodiments a curser is positioned over a desired miniature window and clicked to create a change signal. If no change signal has been detected ( 112 ), the current information in the main display is maintained ( 110 ). Moreover, upon activation of the display screen, a select predetermined set of information will be displayed. If a change signal has been detected ( 112 ), the new information relating to the change signal is displayed in the main window ( 118 ). Also, as indicated in this embodiment, the information is monitored for hazards ( 114 ). If a hazard is detected ( 114 ), the information relating to the hazard is automatically switched to the main window ( 118 ). If a hazard is not detected ( 114 ), the current information displayed in the main window is maintained ( 116 ). 
   Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that any arrangement, which is calculated to achieve the same purpose, may be substituted for the specific embodiment shown. This application is intended to cover any adaptations or variations of the present invention. Therefore, it is manifestly intended that this invention be limited only by the claims and the equivalents thereof.
