Abstract:The TSC ILS localizer model is used to predict the performance of the Texas Instruments "wide aperture" parabolic antenna as a localizer system for runway 28R at San Francisco Airport. Course derogation caused by the new American Airlines hangar is calculated under the assumption that this structure is a metallic perfect reflector. It is found the TI System operated with a "capture effect ratio" of 10dB does not meet Category I requirements. If it is possible to operate the system within equipment limitations at a 16dB capture effect ratio, performance should be adequate for Category I, but it is still inadequate for Category II. This performance is inferior to that predicted for the Alford 22/8 array for the same situation in an earlier study.
