In the Aerial Corps, dragons often fly in formation. British formation, during the early 1800s, flying was taught by Celeritas. Temeraire appears to have a particular aptitude for designing formation maneuvers. Other nations have different formation flying styles. Formations combine the advantages of protection and organisation with the disadvantages of predictability. As such formations can be exploited to their detriment, by a clever enemy as seen in the case of Prussia's defeat by France in 1807.
