Computer Study of Tulsa International Airport Runway 17R Glide Slope Sites

摘要

The terrain at the approach end of Tulsa International Airport Runway 17R is of concern as to its effect on guidance signals radiated from an instrument landing system (ILS) glide slope antenna system. In order to select the antenna system that will result in the least perturbation of signal, the performances of Capture Effect, Sideband Reference, and Null Reference systems were compared using a mathematical simulation model on the National Aviation Facilities Experimental Center's (NAFEC) Honeywell computer. Since the mathematical model has not, as yet, been validated, the simulation results presented in this report are considered preliminary. Results show that performance, for both the Capture Effect and Sideband Reference systems were within Category I limits. Overall, a 2.8 deg capture effect system located outside the taxiway offers the best performance. (Author)
