A holding pattern aid apparatus to enable a pilot in instrument conditions to instantly visualize a holding pattern and determine an appropriate entry procedure, is disclosed. The aid is configured to attach to a kneeboard while permitting the pilot to flip the display from right to left holding pattern with one hand or even the flick of a finger. The apparatus also indicates the appropriate teardrop outbound course and parallel intercept course, as well as providing instant reciprocal headings and a DME Arc aid. A lanyard attach point enables the pilot to quickly find the holding pattern aid when loose and prevents the aid from becoming lost in the cockpit should it become detached from the kneeboard.

The invention claimed is: 1. An apparatus for determining and visualizing a holding pattern and a holding entry, the apparatus comprising: a base having a top edge and configured to be secured to a kneeboard; a disk having a first surface, a second surface distal the first surface, and degree indicia imprinted on the first and second surfaces of the disk, the degree indicia including a symbol representing North; a first disk overlay substantially transparent and imprinted with indicia representing a holding fix, a holding radial, a right holding pattern, and for the right holding pattern a teardrop initial heading, a teardrop entry path, a parallel entry path, a parallel final intercept course, a teardrop entry region, a parallel entry region, and a direct entry region, the first disk overlay rotatably affixed to the disk first surface at about a center of the disk, the first disk overlay configured for easy rotation by one hand for alignment of the holding radial with a predetermined degree on the disk first surface; a second disk overlay, substantially transparent and imprinted with indicia representing a holding fix, a holding radial, a left holding pattern, and for the left holding pattern a teardrop initial heading, a teardrop entry path, a parallel entry path, a parallel final intercept course, a teardrop entry region, a parallel entry region, and a direct entry region, the second disk overlay rotatably affixed to the disk second surface at about the center of the disk, the second disk overlay configured for easy rotation by one hand for alignment of the holding radial with a predetermined degree on the disk second surface; and two connecting brackets pivotally attached at one end to the base and pivotally attached at another end to the disk, the axis of pivot of the disk about the connecting brackets being offset from the center of the disk, wherein the disk may be easily pivoted by one hand to dispose the disk first surface distal the base or to dispose the disk second surface distal the base, and wherein the symbol representing North is proximate the top edge of the base when the disk first surface is distal the base and the symbol representing North is proximate the top edge of the base when the disk second surface is distal the base. 2. The apparatus of claim 1, wherein the base includes a right indicia, the right indicia configured to be visible when the disk is pivoted to dispose the disk first surface distal the base and covered by the disk when the disk is pivoted to dispose the disk second surface distal the base. 3. The apparatus of claim 1, wherein the base includes a left indicia, the left indicia configured to be visible when the disk is pivoted to dispose the disk second surface distal the base and covered by the disk when the disk is pivoted to dispose the disk first surface distal the base. 4. The apparatus of claim 1, wherein: the parallel entry region of the first and second disk overlay is tinted with a unique color whereby the parallel entry region is quickly and easily recognized. 5. The apparatus of claim 1, wherein: the direct entry region of the first and second disk overlay is tinted with a unique color whereby the direct entry region is quickly and easily recognized. 6. The apparatus of claim 1, wherein: the teardrop entry region of the first and second disk overlay is tinted with a unique color whereby the teardrop entry region is quickly and easily recognized. 7. The apparatus of claim 1, wherein: indicia representing the right holding pattern, the holding fix, the holding radial, the teardrop initial heading, the teardrop entry path, the parallel entry path, and the parallel final intercept course are color coded for quickly and easy recognition. 8. The apparatus of claim 1, wherein: the indicia representing the left holding pattern, the holding fix, the holding radial, the teardrop initial heading, the teardrop entry path, the parallel entry path, and the parallel final intercept course are color coded for quickly and easy recognition. 9. The apparatus of claim 1, wherein: the connecting brackets are pivotally attached to the base by fastening means. 10. The apparatus of claim 1, wherein: the connecting brackets are pivotally attached to the disk by fastening means. 11. The apparatus of claim 1, wherein: the base includes an aperture adapted to accept a lanyard for securing the apparatus. 12. The apparatus of claim 1, wherein: the connecting brackets are pivotally attached to the base and the disk by fastening means. 13. The apparatus of claim 1, further comprising a lanyard attached to the base. 14. An apparatus for determining and visualizing a holding pattern, the apparatus comprising: a base configured to be secured to a surface, permitting operation of the apparatus by one hand; a disk having a first surface and a second surface distal the first surface; a first compass rose imprinted on the disk first surface and a second compass rose imprinted on the disk second surface; one or more substantially transparent disk overlays imprinted with indicia representing a holding pattern including a holding fix, the one or more disk overlays rotatably affixed to the disk surface at about the center of the compass rose, the one or more disk overlays configured for easy rotation by one hand, about the holding fix indicia; and a connecting bracket attached at one end to the base, and pivotally attached at another end to the disk, the axis of pivot of the disk about the connecting bracket being in the plane of the disk and offset from the center of the disk, wherein the disk may be easily pivoted by one hand to alternately dispose the first or second surface in position for viewing. 15. The apparatus of claim 14, wherein: the connecting brackets are pivotally attached to the base and the disk by fastening means. 16. The apparatus of claim 14, further including an aperture adapted to accept a lanyard for securing the apparatus. 17. An apparatus for determining and visualizing a holding pattern, the apparatus comprising: a base configured to be secured to a surface, permitting operation of the apparatus by one hand; a disk having a first surface and a second surface distal the first surface; a first compass rose imprinted on the disk first surface and a second compass rose imprinted on the disk second surface; one or more substantially transparent disk overlays imprinted with indicia representing a holding pattern including a holding fix, the one or more disk overlays rotatably affixed to the disk surface at about the center of the compass rose, the one or more disk overlays adapted for easy rotation by one hand; and a connecting bracket attached at one end to the base, and pivotally attached at another end to the disk, the axis of the pivotal attachment in the plane of the disk wherein the disk may be easily pivoted by one hand. 18. The apparatus of claim 17, further including indicia representing a holding radial, a teardrop initial heading, a teardrop entry path, a parallel entry path, a parallel final intercept course, a teardrop entry region, a parallel entry region, and a direct entry region. 19. The apparatus of claim 18, wherein the indicia representing the left holding pattern, the holding fix, the holding radial, the teardrop initial heading, the teardrop entry path, the parallel entry path, and the parallel final intercept course are color coded for quick and easy recognition. 20. The apparatus of claim 17, wherein: the connecting brackets are pivotally attached to the base and the disk by fastening means.
