Turbine Overspeed System
In the Dunnunda forum, early on it was reported that the A/C was operating under a MEL on the TOS for engine number 2. I am wondering why this hasn't attracted wider comment.
Alliance/RR interchangeability. One of my engineer friends has confirmed that either the Alliance or the Trent can be put on the wing of an A380 with no problems. The relevant computers will recognise either and there are no idiosyncratic connections/restrictions on either engine to prevent installation on a wing that prevously had another type.
Maybe RR should be worried in that case?
