Can't get downloaded plane into ATC traffic.

[Fenestrae]

I downloaded a plane and added this to my FS2002 Aircraft folder. I can see and select to fly it when I go to my aircraft selection section.

However, when i want to add it to my atc traffic to fly a route the plane does not show up on the tarmac. I think i am using the correct plane id for that plane but whatever I try it will not appear. If i change it to a planes  that comes standard in SF2002 to fly that route, then it does appear at the gate.
I have used trafficbuilder and TTools to add the flight in the atc traffic but with the same result.
Can someone please help me and tell me what I am doing wrong. Please look at the file info below. I hope provided you with enough information to solve my issue.

Hi Fenestrae. As nobody's answered this I'll have a go. First, did you add the new aircraft to the database in Aircraft.txt & compile it with TTools? Make sure the name you add is correct. It will be the exact Aircraft.cfg title= entry for the particular variant of the new aircraft.

And then, some planes (many I find) are just not compatible with ATC ....
