Elyse Moody writes:One of this morning's breakout sessions gave some answers.Mark Ulliman, general manager - services for GE Aviation, ID'd key ways to get the maximum bang from your fuel buck.1-Minimize deterioration. You can do this by engine core washing, which is becoming more popular, Ulliman said. Trend monitoring and remote diagnostics also can help detect abnormal shifts in performance.2-Get the most effective repairs and overhauls. HPC blades should be your first priority, Ulliman said -- particularly knowing when to repair v.s. when to replace.A final thought, echoed by other speakers as well: Don't make clearances too tight. That actually can hurt your efficiency. Focus should be on the "right" clearance, with roundness as your aim.Larry Slate, managing director - engineering for United, also cited structural modifications, such as winglets for the Boeing 757, that can have a big impact on fuel burn.He and Amir Nasruddin, director of technical support for jetBlue, both noted that removing weight can be as important as adding modifications. Taking out unused items -- even as small as an extra coffeemaker -- can have an impact.
