Newhires will do fine in ER training. The aircraft are easy and fun to fly. The WORLD procedures and consistency of visiting them is probably the Hardest Part. For the Hardest Part, it is going to become a little easier when the Surfaces show up. (the Hardest Part is getting the theatre and airport requirements and procedures down, they change from one part of the world to the next but you will have access to cookbook style checklists).
Have fun, the aircraft (although loud) are great.
