I am led to believe that commercial pilots are required to undertake a skills test in a simulator every six months, and I believe that aircraft which share a common type rating such as 757/767, A320 family and 737-600/700 etc require a test in either of the sub-types associated with the type rating but .......
...... what about crews that are cross qualified across different types e.g. charter pilots in the UK who fly both A320/A321 and A330 aircraft. And also airlines which allow pilots to fly all Airbus FBW types in the fleet such as Austrian airlines - these pilots will be flying in A320, A330 and A340 aircraft - all with different type ratings. Do these pilots have to take a sim check in each of the types they fly?
I also read somewhere that Ryanair had two different flight deck configurations (I believe the autopilot was the main difference) on their 737-200's - and that in order for crews to fly both configurations they took one of their bi-annual sim checks in a sim of one type, and six months later took the sim check in a simulator built to suit the other configuration - could this system be employed by Airbus CCQ'd crews?
