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:

    A new word is like a fresh seed sown on the ground of the discussion.
    Ludwig Wittgenstein (1889–1951)

    Reckoned physiologically, everything ugly weakens and afflicts man. It recalls decay, danger, impotence; he actually suffers a loss of energy in its presence. The effect of the ugly can be measured with a dynamometer. Whenever man feels in any way depressed, he senses the proximity of something “ugly.” His feeling of power, his will to power, his courage, his pride—they decline with the ugly, they increase with the beautiful.
    Friedrich Nietzsche (1844–1900)

    Tonight I will speak up and interrupt
    your letters, warning you that wars are coming,
    that the Count will die, that you will accept
    your America back to live like a prim thing
    on the farm in Maine.
    Anne Sexton (1928–1974)

    Few white citizens are acquainted with blacks other than those projected by the media and the so—called educational system, which is nothing more than a system of rewards and punishments based upon one’s ability to pledge loyalty oaths to Anglo culture. The media and the “educational system” are the prime sources of racism in the United States.
    Ishmael Reed (b. 1938)
