I disagree with VP-F et al. If I am am out of currency for the 90 day rule, but otherwise correctly licensed, it would be perfectly correct for me to fly with another pilot, who was fully current, and for him to hand over control and allow me to make three landings as sole manipulator of the controls, thus regaining my currency. He remains PIC throughout and at no time am I PIC with a passenger whilst out of currency. Him handing over control to me does not make me PIC and him a passenger - he's the captain throughout, and to pre-empt the next argument, he does not need to be an instructor to hand over control to another person. I would record such a flight in my logbook as SNY, the times would not count towards any totals but my landings would count to requalify me.
That's the way I understand it unless EASA have changed absolutely everything.
