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:

    Let us unite on the safe and sure ground of fact and experiment, and we can never err; yet better, we can never differ.
    Frances Wright (1795–1852)

    Our senses perceive no extreme. Too much sound deafens us; too much light dazzles us; too great distance or proximity hinders our view. Too great length and too great brevity of discourse tends to obscurity; too much truth is paralyzing.... In short, extremes are for us as though they were not, and we are not within their notice. They escape us, or we them.
    Blaise Pascal (1623–1662)

    An overturned cart is a warning to oncoming drivers.
    Chinese proverb.

    I need not say what match I would touch, what system endeavor to blow up; but as I love my life, I would side with the light, and let the dark earth roll from under me, calling my mother and my brother to follow.
    Henry David Thoreau (1817–1862)
