Gainsey, full motion is a legal requirement for instrument ratings. Seeing as the RTS does not permit Assy work (as I understand it, can someone on 99 confirm this?) without the motion and uber graphics, they would end up still going to the states once a year (or at least every 13 months) for IRs.
A procedural sim I imagine would be handy, but the training you can achieve is very limited.
Also, if we were to get a sim, we would have the option of full mission sims, potentially linked another sim, if 400M gets ****canned, they have an expansion of the C-17 fleet and start to operate tactically for 30 tonne single pallet airdrop, block 40 CDS and throwing the entirety of D Sqn out the back in a single run!
