Listed below are each of the functions performed by buttons on the tool bar;


 This button is used to redraw the wing or tail.


  This button when selected will cause the ribs to be drawn when the wing or tail is redrawn.

           It is recommended that this function be toggled off if your PC is low or there are a large 

           number of ribs to be drawn. This process can be quite slow.


  This button toggles on and off the visibility of the coordinates of the wing or tail. New 

            coordinates are shown as blue spheres. Old coordinates are shown as red spheres.


   This button is used to increase the size of the wing plot. Clicking on this button is the same as

             increasing the SCALE setting by 0.1 and clicking on the button.


    This button is used to decrease the size of the wing plot. Clicking on this button is the same

             as decreasing the SCALE setting by 0.1 and clicking on the button.


    This button is used to select the HORIZONTAL TAIL SIZING GRAPHHORIZONTAL_TAIL_SIZING_GRAPH .This

              button is not visible if the type of wing is a VERTICAL TAIL or HORIZONTAL TAIL.


     This button is used to select the VERTICAL TAIL SIZING GRAPHVERTICAL_TAIL_GRAPH_SCREENThis 

               button is not visible if the type of wing is a VERTICAL TAIL or HORIZONTAL TAIL.


      This button is used to select the REYNOLDS NUMBER GRAPHREYNOLDS_NUMBER_GRAPH_SCREEN 

                

 This button is used to design SPARS & SHEAR WEBSSPAR_DESIGN.


      This button is used to perform the following calculations; wing area, wing aspect ratio,

                mean aerodynamic chord length and location.


     This button is used to identify a coordinate pair. Click on this button then move the 

               mouse pointer over the wing window. Click in the wing window near or on a coordinate pair 

               with the left mouse button. Winfoil will search for the nearest coordinate pair and will when       

               found , highlight the pair with a grey rectangle. The coordinate pair can then be modified

       using a mouse.


  This button is used to add new wing coordinates with a mouse. If the left mouse button is 

            pushed whilst the mouse pointer in the wing window then a coordinate will be placed at that

            position. Clicking on the right mouse button will cancel this operation. All coordinates are 

            entered as a pair, ie; a top coordinate and a bottom coordinate. Once the position of the top 

           coordinate is set, then the lower coordinate x position will be restrained by the upper 

           coordinate x position. However you are free to vary the y position of the lower coordinate.


 This button is used to accept the new coordinates and redraw the wing.


  This button is used to discard all changes made. All new coordinates will be deleted.


   This button is used to enter wing coordinates using the keyboard. Clicking on this

             button will bring up the Design Coordinates ScreenWING_COORDINATES_SCREEN

{bml bm65.BMP} This button is used to access additional properties for a design. It is only available for Wing or Tail designs. This tab provides access to; Design Targets , Rib View and Skin Thickness, Wing Sweep and 3D View. See
