Quick question...
Who will actually fund the rectification of the 777/Trents? How many aircraft are affected?
a) Will this be picked up by the airlines?, or
b) Will it be paid for by Boeing as its a system problem (for which the solution resides in the RR engine), or
c) Will it be paid for by RR for all affected Trents on 777?
d) a share between b) and c)?
I assume Trent 800s that are not on 777s are not affected? If so this suggests it is the installation of this engine in a 777 that precipitates the problem - hence its a system issue, not just down to the engine (I assume Boeing are the DA for the complete fuel system).
Thoughts?
PS The research proposed in the post above #31/32 is appropriate - you'd first try and properly understand the issue by studying the basic mechanisms for icing, then you could relate it to current designs. If you just started by analysing current designs, you could end up learning very little and it would take longer to technically solve and create robust solutions.
