Winglit, I don't agree with your comments. Why are you trying to imply there may be more than an EPR indication fault? Are we supposed to accept that there may be something else? There was just an EPR indicating fault. Many planes don't even have EPRs. The pilots can look up go-around N1s, so what is the problem?
Because the EPR indication is taken from the EPR transducer inside the EEC and fed to both EICAS computers and the SEI. If all three indications are not working then it would be prudent to assume that the fault lies within the EPR sensing / transducer system and that therefore the engine is operating in N1 mode.
That's why.
So you obviously don't know as much as you think you do, which even more worrying when you think you can circumvent the MEL.
You're one of the swiss cheese holes mate!
