I think it will definitely have a longer than planned "break in" period. Given the GTF issues with the NEO also, it will be a while before we operate them (all GTFs) as planned. This new engine concept is super efficient but I fear super maintenance intensive too. All that being said, there's no going backwards on engine technology. We will have to make operational adjustments like dwell time for warm up and shut down. More touches for MX and better parts distribution/availability will drive up some costs but we will have no choice but to adjust. It could be a tough slog though given management's reluctance to add these costs and accept lower utilization. I don't see the same dispatch reliability as legacy engines ever, but that will have to be accommodated or our famous metrics will suffer. Even the LEAP engines have their issues. As we get closer to squeezing all the energy out of a chemical reaction we will have more exotic ways to absorb and redirect it. There's just no way around adding complexity and that means more maintenance complexity and down time to operate them reliably and safely.
