matt, not sure on the total thrust. just heard that the new rules are a holistic approach. does away with thrust to weight, depends on manufacturers to determine engines for aircraft, no more turbine cds, rewrote the whole thing to something more enforceable, and more realistic to deal with. i would love to see the whole thing. I am just hearing bits and pieces from the rumour mill. supposed to be announced tomorrow on the ama website, or was supposed to be. from what I have heard this is a real move in the right direction. just hope it sees the light of day.
