FS9 with FSNaviagtor ILS behaving strangely

Pro Member Trainee

Hi, can anyone help me with a problem that has been baffling me. I'm using FS2004 with FSNavigator. On some airports (such as Gran Canaria) when I capture the ILS after selecting NAV the plane turns round (as if the ILS is pushing it in the opposite direction?). It doesn't matter how many approaches I make, from what altitude or speed, exactly the same thing happens once the ILS is established. Could this be something to do with the ILS binding in FSNav as FS9 ATC doesn't even recognise an ILS runway? Or am I doing something wrong? Any help appreciated.

Your best bet would be to email him and ask.

Thanks for that. I have written to Bob and will post here in case anyone else has had a similar problem.

I think I've figured this out from this:

"Some runways have an ILS on one end, but instead of having a seperate ILS on the other end, they have what is called a "localizer Back-course." This is basically the same beam, so if rw 9 has an ILS, rw 27 for example could have the same Localizer beam as the one used on runway 9, except it would appear to be reversed. So, if the ILS needle moves to the left, instead of flying left you would fly right (Often called "dragging" the needle). This is the exact opposite of how you fly a normal approach, so if you want the autopilot to fly it, it requires a different function - the back course hold. Note that most back courses do not have glide slopes, so you will still have to control altitude."

Now my only question is how to identify runways that have a localizer back course?

😀 Your part way there, don't quit now.
Good work!
