If one uses the NGFMC upgrade as the metric, there are 4 (of 5) RR production -400s not getting the new FMCs. One might presume those are the aircraft destined for AHK. The ERFs, HUP, and the BCF from the desert are getting the new FMCs, presumably for ops within CX. However, it's not hard to imagine a gradual AHK takeover of CX freighter regional ops, at least in part if not whole.
