Zero flight time conversions are the normal now on modern airline types.
I often wonder when passing Brize why there always seem to be A400s and Voyagers bashing the circuit. I presume they came with Level D simulators, which negate the requirement in the civil world, for any Base training on a Conversion course.
The first time I flew a”real” B747-400 was as a Captain with a full load of pax to JNB. The Trainer in the RHS, was always the pilot who carried out your last sim before Route Training. The 2 FOs were normal line guys.(whoops, sorry, persons)
Obviously more hands on time is required for RAF military roles, but not on a conversion?
