Ground Proximity Warning System

A ground proximity warning system (GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration defines GPWS as a type of terrain awareness warning system (TAWS). More advanced systems, introduced in 1996, are known as enhanced ground proximity warning systems (EGPWS), although sometimes confusingly called terrain awareness warning systems.

Famous quotes containing the words ground, proximity, warning and/or system:

    Just as the hand that strikes the ground cannot fail,
    So is the ruin certain of him who cherishes anger.
    Tiruvalluvar (c. 5th century A.D.)

    The triumphs of peace have been in some proximity to war. Whilst the hand was still familiar with the sword-hilt, whilst the habits of the camp were still visible in the port and complexion of the gentleman, his intellectual power culminated; the compression and tension of these stern conditions is a training for the finest and softest arts, and can rarely be compensated in tranquil times, except by some analogous vigor drawn from occupations as hardy as war.
    Ralph Waldo Emerson (1803–1882)

    We have not the motive to prepare ourselves for a “life-work” of teaching, of social work—we know that we would lay it down with hallelujah in the height of our success, to make a home for the right man. And all the time in the background of our consciousness rings the warning that perhaps the right man will never come. A great love is given to very few. Perhaps this make-shift time filler of a job is our life work after all.
    Ruth Benedict (1887–1948)

    We find ourselves under the government of a system of political institutions, conducing more essentially to the ends of civil and religious liberty, than any of which the history of former times tells us.
    Abraham Lincoln (1809–1865)
