Abstract

Present novel and non-trivial methods for electronically recording a taxi route on a display unit are disclosed. In one method, a tax route entry window (“TREW”) such as a taxi clearance entry window is used to present in smaller windows surfaces and next intersecting surfaces from which a pilot sequentially selects surfaces based upon surfaces stated in a taxi clearance. In another method, the TREW is comprised of an airport-specific keyboard or a traditional keyboard with visually-variable, interactive buttons, where an activation or deactivation of each button is dependent upon surfaces specified in the taxi clearance and potential intersecting surface. In another method, selections are made on the TREW and surfaces corresponding to the selections are highlighted in an image presenting a map of surfaces. Additionally, the image presenting a map of surfaces may be panned and zoom to the size of the highlighted surface.
