I was recently having a discussion with some people who are experienced on the A330 using RR Trent 700 engines.
The only jet engine that I have previous experience with which uses EPR as a take-off thrust setting is the B-737-200 with JT8D's. Following a very famous accident in Washington DC, Boeing implimented a cross-check procedure between EPR and N1 (the PT1 Probe on the JT8D's were iced over producing a faulty EPR indication).
I asked whether such a cross check exists on the A330 but was told no. Haven't found any other reference source either. I understand that the powerplant on the type has an abnormal "N1 mode" and am wondering whether a similar situation which put a nail in the coffin of the Air Florida 737 would cause the FADEC to revert to rated or unrated N1 mode?
Thanks, in advance, for all intelligent replies.
