Embodiments of the invention provide a method and apparatus for indicating aircraft height relative to an obstruction in a terrain awareness warning system. The method includes receiving data indicative of geographic features of an obstruction, lateral distance of the geographic feature from an aircraft, height and flight path of the aircraft, calculating a projected height of the aircraft at the location of the obstruction using the data, generating a result signal, and displaying a colored indication on a display screen based on the result signal. The apparatus includes inputs for signals from instruments measuring height, flight path, and location of an aircraft, as well as an input for an instrument providing information about geographic features of terrain surrounding the aircraft. The apparatus includes a means for employing the signals to calculate an effective height of the aircraft relative to the terrain, and a screen display for graphically displaying the results of the calculation.

1. A method for providing an indication of aircraft height relative to an obstruction in a terrain awareness warning system, comprising:receiving a first datum indicative of a geographic feature of an obstruction; receiving a second datum indicative of a lateral distance of the geographic feature from an aircraft; receiving a third datum indicative of a height of the aircraft; receiving a fourth datum indicative of a flight path of the aircraft; calculating a projected height of the aircraft at the location of the obstruction using the first through fourth data; generating a result signal based on the projected height and the first datum; and displaying a colored indication on a display screen based on the generated result signal.
