Hey Nage!
Process is as follows:
1. Wait till mission time is 1118 (12 mins from spawn). Clock is far left side of instrument panel.
2. Start your engine.
3. Hit tab. Select your flight. In your case, option '3', Red. Ovy you select option '4', White, and Arg0n option '5', Blue.
4. Then select option 'Q', Technical
5. Then select the Start Engines Option
All members of your flight will start their engines. Before they do start pulling out from your dispersal point.
These are the routes the AI will be following; try to keep to them!
I have placed lights across the field to mark the runway - also the start of the runway is marked by some vehicles and an elevated green light to help guide you to that point.
The AI should not collide with you if you are careful, and most of the time they will stop and let you in if you get on a collision course - but just be wary!
