Yes - understood.
My point is that the 80E1 is a fairly mild derivative of the 80C2, and was probably certified based on a "same core" philosophy - i.e. the high compressor, burner and high turbine are essentially identical in design to the 80C2. The fact that the fan diameter of an 80E1 is a few inches larger than an 80C2 is probably not of consequence to flameout resistance. By the same token, there are plenty of 80A engines out there on early 767 airplanes. I think I have heard that they were taking the same prevention measures as for the 80C2 operators.
The fact that GE/Airbus are recommending the same operational prevention measures as the other -80 engines might suggest that they believe the 80E1 has the same issue - it even says that in the operator letter posted earlier. Perhaps a -80 is a -80 regardless of A, E or C2.
Does anyone know if Airbus released these operational recommendations for the A300 and A310? Also, how many A330's with 80E1 engines are out there?
