I dont know if there is a scheduled trainer/time for the teachings of functons,formations, and opperations of bombing. But as a service we would like to add to the community here, our group generally flys scheduled training missions on Tuesday nights which covers all of the above. Generally in one of the MA's, but also in the TA if necessary to get you going with the basics.
If you happen to see us , and have a few questions, or just want to have a tight group to test/train your formation flying on. Just give a shout on VOX 184 , or PM here. Were glad to help out.
