The jump sessions defined in 3° of articles A. 322-150 and A. 322-151 as well as in article A. 322-152 require at least the presence of two designated autonomous parachutists, one on the ground, the other in the air, who coordinate, in liaison with the pilot, the general conditions of the drop. However, the tandem instructor may ensure the safety of his release alone in flight.
On board the aircraft, in freefall and under canopy, the tandem instructor may not be entrusted with any mission other than that of teaching his student.
