Not sure if you've done much airborne instruction BEagle
On ME aircraft, several thousand hours as an A2 QFI, IRE, AARI on the VC10 & VC10K, thank you very much. And you,
FixClrEnt?
ME aircraft do NOT fly 'routine pairs departures' or 'radar-to-visual' recoveries in close formation. 30 deg AoB is quite adequate for AAR manoeuvring as it gives a slight margin over the standard max bank angle of 25 deg; higher bank angles are simply not required. They also pose the risk of exceeding buffet boundary limits or g limits.
There is NO need for the Phenom to be flown in close formation at higher bank angles, although some experience as a singleton at higher bank angles may be of benefit for those who will later fly the A400M or C-130J in the tactical role.
