Daniel Churchman 1050104 Posted January 24, 2017 at 12:24 PM Posted January 24, 2017 at 12:24 PM Have a look at KSAT ILS12R and ILS30L. Both use 110.9. 1. How does this work in real life 2. Do our aircraft in FSX handle this OK? Link to comment Share on other sites More sharing options...

Trent Hopkinson Posted January 24, 2017 at 11:44 PM Posted January 24, 2017 at 11:44 PM - Tune the right frequency - tune the correct inbound course - be approaching the correct runway FS won't "see" the ILS which is "pointed" the opposite direction.

Robert Shearman Jr Posted January 25, 2017 at 02:31 AM Posted January 25, 2017 at 02:31 AM From VATSTAR's lesson on Back Course Approaches: "While multiplayer servers and networks like VATSIM have turned the hobby into an entire interactive world populated by many of the same types of actors that exist in reality, flight simlulation software is, at its roots, a single-user system. In the real world, airport operations staff decide which ILS systems to turn on and which ones to turn off; in the virtual one, all ILS systems are on if the pilot is within receiving range of them. Simulated runways which have two separate ILS systems in opposing directions using the same frequency will automatically "pop" from one to the other when the pilot crosses a point approximately abeam midfield. Two pilots on VATSIM approaching that scenario simultaneously from opposite directions with their NAV radios tuned to the same ILS frequencies will each see a different ILS transmitter as being active; obviously, this is not the case in the real world, where only the ILS system for the runway's active direction will be transmitting at any given time."

David Zhong Posted January 25, 2017 at 10:11 AM Posted January 25, 2017 at 10:11 AM Rob, not sure I would describe that as a "backcourse" approach, which is when you fly (e.g.) the runway 36 localizer from the north to land on runway 18 (i.e. flying the localiser backwards), whereas that is simply two separation ILS installations that happen to be on the same frequency.

Robert Shearman Jr Posted January 26, 2017 at 02:43 AM Posted January 26, 2017 at 02:43 AM I didn't describe it as a back course approach. I said that the section I quoted came from our lesson on back course approaches. Cheers, -R. Link to comment Share on other sites More sharing options...
David Zhong Posted January 26, 2017 at 07:53 AM Posted January 26, 2017 at 07:53 AM Fair enough, although I hope you do see how someone could interpret it that way! David Zhong Link to comment Share on other sites More sharing options...
Robert Shearman Jr Posted January 26, 2017 at 05:09 PM Posted January 26, 2017 at 05:09 PM That discussion is included in that lesson to distinguish the phenomenon of two opposing ILSs from an actual back course approach. But I do see what you're saying. Cheers, -R. Link to comment Share on other sites More sharing options...
Lorenzo Stobbione 1368867 Posted January 29, 2017 at 01:13 PM Posted January 29, 2017 at 01:13 PM If I am not wrong XPlane has the option of turning off downwind ILS in order to let pilots have only one active course.
