Missing aircraft on Simobjects

[Bubblehead]

I have an aircraft in FSX which shows on the Aircraft Select but am unable to find it in the FSX Simobject/Airplane list. The aircraft description in FSX is as follows:
Boeing 777-300 Virgin Australia Airlines
Boeing 777-3ZG/ER
VH-VOZ
Without the aircraft listed in the FSX/Simobject/Airplane I am unable to do changes. This is not a default texture aircraft. I have three other B777s each with completely different cfgs. Any ideas why this is happening?

Each aircraft folder has an aircraft.cfg file.

In the aircraft.cfg file there are [fltsim.x] sections.

My original problem was that because it did not list the aircraft I was unable to get to the aircraft.cfg file. However I found out what the problem was. The aircraft was not listed as Boeing 777-300 rather it was listed as "voz_773_vh-vph". No wonder I couldn't find it. I changed it to Boeing 777-300, added its "thumbnail.jpg" pic in the texture section and voila! everything is OK now. Thanks anyway gents.
