In Europe, the time logged in a full flight simulator doing type rating, lpc and opc can be credited against the 1500 hours required for an ATPL issue.
It can not be credited against any of the other requirements - P1, Multi Pilot time, Night etc.
It is logged as and referred to as Simulator Time.
Similarly, FNPT time can be credited against the appropriate part of training requirements of the CPL course and of course the IR training course can be mostly FNPT time.
However, if you tell me that you have xxx hours total, yyy hours P1 and zzz hours IFR and uuu hours night then I expect all those to be in an aircraft.
The fact that an Authority issed a rating, licence or certificate based on the combination of P1 time (in an aircraft) and time in a sim, does not change the actual amount of P1 time that the person actually has.
So if the Authority wish to issue a certificate to a pilot based on a combination of aircraft and simulator time then they can - but the logbook time should still reflect the true experience situation.
