WRONG--anyone with any experience with GPWS knows that a properly flown approach will generate NO GPWS warnings, particularly not a "PULL UP! TERRAIN!" warning, which is not part of the system. GPWS looks for several things: 1) Excessive rate of descent below a specified altitude. 2) Excessive rate of closure with terrain below another specified altitude. 3) Incorrect flap/gear configuration at low altitude. 4) Descents on takeoff or go-around before reaching a specific altitude. NO warnings are generated during a properly configured approach using normal stable approach parameters. And yes, GPWS is a major safety contributor. A superior pilot uses his superior judgement to avoid using his superior skill.
