FSX Creating an approach for Isafjordur Airport (BIIS)

[Alexander Roswell]

Hello dear flightsimmers!

I'm new to Airport Design Editor and have only used it to add parking ramps, create taxiways and easy editing. I have Iceland X by Aerosoft installed, but at some airports the approach for AI traffic goes through mountains and some times disappear. A good example is the Isafjordur Airport (BIIS) which is known for having a difficult approach due to it's position between the mountains.

I want to schedule AI traffic to this aiport, but because of the approach it's not possible. That's why I wish to create my own ILS approach which is more realistic. But with my little knowledge about ILS approaches and creating waypoints and charts and so on, I seek help from people who hopefully have a little more experience than me in creating custom approaches.

If somebody could help me explaining what's necessary when creating an approach and how do you do it?

I've attached a picture of the Airport and how I wish the approach should be!

It's not so easy,but if you have the time read all this : http://www.fsdeveloper.com/forum/threads/tutorial-approaches.14074/

And let me stress, you can have AI aircraft in good weather only do this:

These are all in the MAIN SECTION of the ILS approach in ADE; AI aircraft do not fly legs.

1. Fly to the initial point specified in the main ILS section, from all points of the compass
2. Cross the initial point at the altitude specified in the main ILS section
3. Turn to and fly the heading specified in the main ILS section
3. Fly to the extended centerline of the approach runway
4. Turn to the runway heading
5. Land

They will descend steadily from the initial point to the runway.

Hope this helps,

Hello Tgibson!

Thanks for taking your time to explain. Unfortunately I didn't understand much of that. The airport has no approaches at the moment so I added a new approach and that's where my knowledge makes me hold short for the moment. I've been reading a lot of these threads here on the site and every explanation that I've stumbled over seems well explained, but I don't understand that much.. I picked up that I had to add a FAF terminal waypoint (correct me if I'm wrong!) but where should it be placed and how many of them should it be?

Confused over here

This is what's showing when opening the airport in approach mode:

 

[tgibson]

There can be one FAF for each runway with an ILS. Where you place it is entirely up to you - I would place it so AI aircraft can arrive at this location at the specified altitude from all directions. It should also be placed so an AI aircraft can turn to the specified heading, miss all the mountains on its way to the extended centerline, and then turn to the runway heading. That's all determined by the terrain.

Okey, but where should the ILS localizer be placed? And if you look at the picture I've attached, is it okey if I place it paralell of the runway to the south?

 

[tgibson]

The localizer can be placed where you like it for the flyable aircraft; it has no effect whatever on AI aircraft approaches. Normally the long green arrow is placed at the *far end* of the runway, so you can get reception all along its length. If you want the ILS needle to be centered when you are aligned with the runway, place it exactly on the runway centerline. For LOC type approaches (not true ILS's), you can place it anywhere. If equipped with a glideslope, place the small green arrow at the touchdown point, alongside the runway.
