Expired IR on Jar License advice needed!
However, IF you are going to do an initial type rating on the ME jet, as you say, surely that will include more than 3 simulator session. Also I believe the UK actually has an exemption regarding the IR currency, saying in the lines of, that IF you keep your IR current on a third party licence (basically recognised ICAO licence) then all you have to do an LPC including the IR renewal. Look it up in CAP 804.
