Not sure of the actual hour requirement Percula however as a junior pilot you’ll be nowhere near the seniority required for the fleet, especially now it’s down to one aircraft. To the best of my recollection it’s actually more senior than the 787 and the rest of the long haul fleets so the required Airbus hours would be a given by the time you achieved that level of seniority. (Unless you joined in Gatwick on the Max
but that’s another story!)
