1. A method of displaying an en-route visible terrain display for an aircraft comprising:

  • representing each pixel of a terrain display using a geographical location and an elevation above the location, each pixel further represented using at least one of a color value and a grayscale value;

    receiving a minimum elevation value;

    setting the at least one of a color value and a grayscale value of the pixels represented by an elevation value less than the received minimum elevation value to a uniform value; and

    displaying the en-route visible terrain display such that pixels representing terrain that includes an elevation value less than the minimum elevation value are displayed with the uniform value such that non-terrain-impacted, primary-navigation areas of the display are more easily readable.
