I'm a virtual Air Traffic Controller with the VATSIM group. Haven't done if for a while though. Waiting to get highspeed internet before getting back into it deeper.
Anyway, if we are talking about STAR aproaches, Not all airports have them. Mostly class B and C airports. Some class D if they are really busy. If I remember correctly seems like I noticed that most military airfields didn't have ILS's they use something else. TACANS and maybe presision approach radars. I'm not certain.
Ah, ok. I just brought up one of my charts and I remembered correctly.
For a example of what I am talking about, go to
www.myairplane.com and get the chart package for KNKX, Miramar MCAS.
As you can see they have TACAN PAR approach proceedures, but no ILS or STARS.
This might shed some light on the problem. I might not show on the GPS unless its there in the real world. You will have to force program it.
