Gate dude... That has been my understanding too I just have not been able to verify that yet.
For commercial validation
1000 PIC or SIC in airline ops in a 2 crew A/C ( accord. to typecert. Or ops reqs. )
FAR25 A/C.
For ATPL validation
1500 PIC or SIC Requirments as above.
I have been trying to verify this as well as would that validation be issued permanently for EU citizens ???? and some more ????
