For most ILS approaches, though, the pilot has to make a decision at some point close to the ground. Regardless of what his instruments are showing, can she see the touchdown zone, enough of the runway, and the runway lights? This "threshold" changes depending on the runway, but it's usually between 300 and 500 feet, which will give the pilot enough time, if she doesn't see anything because it's too rainy, snowy, foggy or cloudy, to declare a "missed approach," throttle up, retract most of the drag-inducing flaps, and then retract the runway gear, and pitch up.
