These are transmitted from a phased array of co-located antennas. One is amplitude modulated at 90 Hz, the other at 150 Hz. Two signals are transmitted on one of 40 ILS channels. ANNEX 2-3 Table of Frequencies for Radio Stations Using ACAS, Aeronautical DME, TACAN, VOR, ILS, MLS, ATCRBS and GBAS 1. 2) 3023kHz and 5680kHz are for worldwide use (refer to ANNEX 2-1). LOC carrier frequencies range between 108.10 and 111.95 MHz (with the 100 kHz first decimal digit always odd, so 108.10, 108.15, 108.30, etc., are LOC frequencies and are not used for any other purpose). 1) The frequencies indicated in above table are the carrier frequencies of SSB. The LOC signal is in the 110 MHz range while the G/S signal is in the 330 MHz range. Localizer (LOC) and glide slope (G/S) carrier frequencies are paired so that the navigation radio automatically tunes the G/S frequency which corresponds to the selected LOC frequency. The centre of the glide slope signal is arranged to define a glide path of approximately 3° above horizontal (ground level). Similar to the localizer, the GS signal is amplitude modulated with 90 and 150 Hz audio tones and transmitted on an carrier signal. The GS transmits in the 328 to 336 MHz ultra high frequency (UHF) portion of the electromagnetic spectrum. Principle of operation Ī glide slope station uses a phased antenna array sited on a tower which is offset approximately 250 to 650' to one side of the runway centerline and approximately 750 to 1250' beyond the approach end of the runway, adjacent to the runway touchdown zone. In aviation, instrument landing system glide path, commonly referred to as a glide path ( G/P) or glide slope ( G/S), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path of descent". Would you care to provide some insight or should I just post to the forum.Emission patterns of the localizer and glide slope signals Glide slope station for runway 09R at Hannover Airport in Germany I have been usually flying, programming the FMS and it got me from start to finish, including a smooth automatic landing, without the need to mess with the frequencies. The results of tests conducted indicate that the quality of the course line of VORLOC is subject to its siting. The 748 has no special receiver on the stack, like for example the 757 or 767, where you enter an ILS frequency. This equipment was designed to be used in a manner similar to a standard localizer but operates on VOR frequencies with the standard VOR receiver and instrumentation. I have therefore some follow-on questions regarding the FS2020 version that simply isn't obvious to me regarding broader topics like, having landed at an airport now deciding to ge "free flight" to another destination, is there anyway to 1) reverse the route using it to return to the originating airport without having to do a restart of FS2020 to return AND 2) is there a way to get to the flight planner without having to restart FS2020 to create a flight plan-a true free flight mode. The report describes a low cost system called VORLOC. You know a billion monkeys can get Shakespear eventually so it seems best to ask questions rather than attempt to research on my own given the huge amount of subject content in a manual if one existed. The more familiar I am getting with the 2020 version (quite a curve in some respects) the more question arise. Presume the readme other contents of the folder are OK for residing inside the community folder as well. I did not make any changes to it just loaded the extracted worldmap filter folder placing it in the community folder since it appears that all filters are active by default with this mod before I attempt any particular configuration otherwise. Tim got the file you created and posted to the library.
