The highly paid FSTA lackeys were certainly given all the info they needed to come up with a great solution. Personally, I would always prefer the mental picture and calculations way
Well, not particularly well paid non-FSTA 'lackeys' have developed a reliable trail planning and management system which has been in operational use in other Airbus tankers for several years now. Which does
not use the archaic, mathematically non-rigorous methodology of the primitive 'RAPS'.....
Quite why AiM haven't been more interested in this reliable, combat-proven 'great solution' system already flying in their other tanker-transports? ICATQ! Perhaps 'No inventado aquí'??
