I suspect there may be threads on this topic, but I also suspect a new one is appropriate.
I've seen there are various formation clinics out there, most designed to faciltiate OshKosh arrivals.
What's the training syllabus look like?
Who are the instructors? what are the minimum experience requirements for instructors?
Do you have minimum experience requirements to fly #3 and #4 and #xx, as opposed to just #2?
How do you qualify a flight lead? Does somenone give a "flight lead checkride"?
Is there a different qualification for 2-ship lead, 4-ship lead, and XX lead?
What does the briefing look like (is there a standard template?)
Are flight leads carefully trained to brief the template?
Do people sometimes "train" each other outside these clinics and then fly formation just in their small groups (I presume so). How do you assess/admit someone new to the group?
In a fighter squadron everyone knows each other, everyone's had the same training, and everyone knows what everyone will do in every situation. How does that work with Mooney formations, especially when there may be pilots in formation who do not have militrary/fighter experience?
other topics/considerations welcome...
