DOWNLOAD EBOOKA joint NASA/FAA flight test has been made to record instrument landing system (ILS) localizer receiver signals for use in mathematically modeling the ILS localizer for future simulation studies and airplane flight tracking tasks. The flight test was conducted on a portion of the ILS localizer installed on runway 25L at the Los Angeles International Airport. The tests covered the range from 10 to 32 n.mi. from the localizer antenna. Precision radar tracking information was compared with the recorded localizer deviation data. Data analysis showed that the ILS signal centerline was offset to the left of runway centerline by 0.071 degrees and that no significant bends existed on the localizer beam. Suggested simulation models for the ILS localizer are formed from a statistical analysis. Hueschen, Richard M. and Knox, Charles E. Langley Research Center RTOP 505-64-13-04...

DOWNLOAD EBOOKThis Technological Note describes the instrument landing system (ILS) math modeling performed by the Federal Aviation Administration (FAA) Technical Center at the request of the Southern Region. Computed localizer data are presented showing the effects of two hangar buildings (Braniff and Comair) on the performance of an ILS localizer proposed for runway 17R at the Orlando International Airport. The Southern Region is concerned that radio frequency (RF) signal reflections from the two hangars may degrade the localizer course beyond Category II/III tolerances. Modeled course structure results indicate that Category II/III localizer performance should be obtained with the Wilcox Mark II, 14-element, dual-frequency log periodic antenna with both hangar buildings constructed at the currently proposed locations. Computed clearance orbit results indicate satisfactory linearity, course crossover, and signal clearance levels. Data are also presented showing the computed performance for a glide slope proposed for runway 17R at the Orlando International Airport. The null reference glide slope will be located 1050 feet back from runway threshold and 400 feet left offset of centerline. Glide slope modeling computed only the effect of terrain in front of the antenna system and was conducted with the GTD-2D model because of limited terrain data availability. Modeled path structure and level run plots are provided for the proposed null reference system. Modeled results indicate that the proposed site should meet Category II path structure, linearity, and symmetry tolerances. Keywords: Instrument landing; Instrument landing system math modeling; ILS Localizer; ILS Glide slope. (kt).

DOWNLOAD EBOOKPosition data on aircraft flying Instrument Landing System (ILS) approaches from 40 nautical miles (nmi) down to runway threshold were collected at Los Angeles International Airport (LAX) between November 26, 1991 and April 25, 1992. The purpose of the data collection was to provide an accurate database of navigational performance of aircraft flying ILS approaches at distances between 10 nmi and 32 nmi. Aircraft position data were collected using the in- place LAX surveillance primary and secondary radars. The data were reduced and analyzed at the Federal Aviation Administration (FAA) Technical Center by ACD- 340 personnel. The discussion in this Final Report concerns the accuracy of the collected position data and possible sources of error in the data collection.

DOWNLOAD EBOOKThis Technical Note describes the instrument landing system (ILS) math modeling performed by the Federal Aviation Administration (FAA) Technical Center at the request of the Southwest Region. Computed data are presented showing the effects of several proposed hangar configurations on the performance of the ILS localizer for runway 18R at the Dallas-Fort Worth International Airport. The Southwest Region is concerned that reflections from the proposed hangars may degrade the localizer course beyond category II tolerances. Modeled course structure results indicate that category II localizer performance should be obtained with the existing 14/6 Type IB antenna for the proposed hangar configurations. Computed clearance orbit results indicate satisfactory linearity, course crossover, and signal clearance levels.
