ILS Runway selection?

[Fozzer]

Hello Chums... ;)...!

FS 2004: General Aviation. On-Line Multiplayer, (With FS Navigator).

When flying on line in FS 2004 Multiplayer, the normal ATC Radio communication is not available, so the airfield landing instructions are not available to the pilot.

When the ILS approach frequency is known, and can be dialed into the NAV Radio, bearing in mind that each end of the runway carries the SAME ILS frequency, how does one know whether to select either the "Approach" button, of the "Back-course" button to land on the desired threshold?

Presumably, the same problem would occur if the Pilot's Com Radios were out of action so that he/she was unable to contact the Airfield for Landing instructions, but able to carry out an ILS approach?

I am assuming that a normal Approach is carried out on the Airfield's preferred Runway threshold, and a Back-Course approach is flown on the non-preferred/non-approved Threshold?

(Also, why is each end of the runway not allocated a different ILS Frequency, for simplicity?)

The Approach plates for some Airfields only carry a ILS approach for one end of the runway only....no problem...
.....my confusion arises when the Airfield Approach plate carries the ILS Approach frequency for BOTH ends of the Runway!

(Remember: Multiplayer; So ATC instructions are not available!)

Cheers All... [smiley=thumbsup.gif]...!

Example: "Appr" or "B/C".?..>>>



Note: Pressing the WRONG button(s) will turn the aircraft 180 degrees from the desired approach!

Does that mean you've been landing backwards on occasion

..landing backwards is my specialty, Craig....

Easy.
The opposing end ILS is switched off, so there is only one ILS transmitter active.  :)

Just carried out a typical trial:

Stockton Metro.  KSCK.
Runways 11L/29R.
ILS Frequency:109.10. (Both ends of the runway)

Runway 29R is the "Normal" approach runway, using the "Appr" Button.
Runway 11L is the "Reverse/Back-Course" approach runway using the "Appr" + "Rev/BC" Buttons.

The noticeable difference being that the Course/Height indication appears on the HSI Instrument only during a "Normal" approach, but not on the Rev/BC approach, where the Course is held automatically, but the Height must be controlled manually.

How would one know in advance, which to press; "Apr" or Rev/BC" buttons during an ILS approach?

Pressing the wrong combination of ILS Button(s) results in the Aircraft quickly turning 180 degrees in the opposite direction!

The only way to know would be to look at an approach plate, or cheating, to look at FS's map view, which nicely marks ILSs.

The noticeable difference being that the Course/Height indication appears on the HSI Instrument only during a "Normal" approach, but not on the Rev/BC approach, where the Course is held automatically, but the Height must be controlled manually.

That's because they are using the same localiser. One way to find out would be approaching the ILS on the back course will mean that the G/S flag on the HSI will remain in view, and the glidepath bar should remain at the periphery of the instrument, as the kit is not receiving an ILS Glidepath signal. On full ILS end this flag should remain clear, and you will also get glipepath bar movement before you intercept it once on the localiser.

Back course ILS's are a silly idea, and hopefully before too long will be things of the past.
