• • • repairs. (Large air carrier aircraft will prefer a precision approach to 27L, the longer runway.) At night, all arrivals would be encouraged to use 27L to keep aircraft farther away from nearby homes. This noise abatement procedure exists today and would be strengthened with an ILS on 27L. • Visual approaches — With two ILS's, guidance for visual approaches to either runway would be more precise, which enhances safety. Most arrivals into North Field are visual approaches. The Aircraft Owners & Pilots Association estimates that only about 10% of pilots are certified to fly IFR. Consequently, most general aviation arrivals into North Field will continue to use visual approaches. In addition, most general aviation pilots will continue to prefer landing on 27R because it is closer to aircraft parking and decreases taxi time. e ILS on 27L — Most IFR traffic will prefer landing on 27L, the longest runway on North Field. • ILS on 27R keeps altitudes higher. If the ILS is removed from 27R, instrument landings could still occur but they would use non - precision approach techniques. An advantage to keeping an ILS on 27R is that the ILS glide slope keeps aircraft on a "continual descent" approach to the runway, which often results in higher altitudes as aircraft approach the runway. Non - precision, "step down" approaches tend to put aircraft at lower altitudes farther from the runway than continual descent approaches.
