I am curious to know what, if any, procedures exist for a formation flight situation where an aircraft in the formation has to exit because of problems but to do so without causing problems for others in the formation. Ie- if you are in the front right, you pull up and turn right?
The escape is pre-briefed. If there are two or three of you, it's pretty straightforward (I hope - left or right as appropriate). The more aeroplanes, the more complicated. For example, a thirty degree bank right and up, a sixty degree bank right and up, a thirty degree bank and down, etc. Your mate may follow, especially if you're in the middle!
The most I ever did was a fourteen-ship (required a bit of thought)!!
