This necessitated an additional modeling effort due to changes in aircraft docking arrangements, the addition of taxiing aircraft, and a Delta ramp operations control tower. Computed data are presented showing the effects of airside terminals with simulated docked and taxiing aircraft on the performance of an ILS localizer proposed for runway 17R at the Orlando International Airport. The Southern Region is concerned that reflections from two proposed airside terminals with docked and taxiing aircraft may degrade the localizer course beyond category II/III tolerances. Modeled course structure results indicate that marginal category II/III localizer performance should be obtained with the Wilcox Mark III, 14-element, dual-frequency log periodic antenna and both airside terminals with docked and taxiing aircraft at the currently proposed locations, excluding aircraft taxiing parallel to the runway. Category II/III course structure results are not obtained when the parallel taxiing aircraft are included in the reflecting source configuration. Computed clearance orbit results indicate satisfactory linearity, course crossover, and signal clearance levels. (FR) 收起
