The "standard of the brief" will be unclear if you weren't there.
That's why I said it was unclear! Duh! (as my daughter would say)
If you are telling me that a group of pilots from completely different areas, sometimes languages, backgrounds, aircraft types have a set of SOPs that are as formed as a set of military SOPs then I will gladly retract my statement.
On the other hand, if the SOPs that are in place allow for an aircraft to have a near miss with two others on finals then another aircraft of a similar type to break from the number 3 position and hit his leader (not even the no. 2!!!) then I might suggest those SOPs could be ever so slightly tweeked.
