The Mk3 is replacing the SK4 and will be based at Yeovilton. Any one with any sense will move the Mk3 sim to Yeovilton, keep it connected to the CH47 complex wherever that ends up and ensure that the Wildcat sim is also networked (indeed it should be in the same building).
No, No, No.... It doesn't work. It has been tried and although it is a nice thing to do the training benefit is minimal and not worth the expense. In fact it will be cheaper to get a real Chinook and Wildcat airborne at the same time than to try and network the Sims when they are 50 miles apart.
