Airbus A320 Initial/First Officer Training
Typically SSTR organisations will pair together trainees for the course. Learning the Airbus involves becoming competent at both Pilot Flying and Pilot Not Flying duties so seat changing is the norm during sim sessions involving similar rank candidates therefore half your time will be spent in the seat you hope to occupy. A slight drawback is that PNF duties are learnt in the wrong seat but this is not greatly significant.
Good luck !
