What is the design assurance level of the A310 MPS?
Also, previous users of the 310 MPS do not share the same view as Beagle. I know a couple of guys who used it with the RCAF and they don't have too many good words to say. In fact the most recent chap was teaching RAPS to the aforementioned Air Force.
So I think it is unfair to say that the 310 MPS is the way to go, whilst I also agree the state of the Voyager system is far from ideal.
However, the system software is now Certified and Qualified and we await the final roll out in the near future.
Oh, and that nasty manual calculation thing called RAPS worked very well for a number of years, the idea of going to the USAF way really worries me. They divert many more trails due to fuel shortages, but have the airfields and tankers worldwide to operate such an inefficient system.
