Aircraft Weight Reduction and Engine Health Monitoring
Saving weight and keeping a close eye on engine parameters can save up to 4 percent in fuel burn per flight hour.

While relatively low fuel costs in the recent past have significantly sustained airline profitability, the fact that oil prices have been on the rise for some time now is pushing fuel-saving initiatives higher up on airline management's agenda. Operational considerations that focus on fuel burn, while not compromising safety, have been known and implemented by airlines for quite some time. But engineering-driven solutions for saving fuel have been much less scrutinized, despite the fact that aircraft weight reduction and engine health monitoring can result in high levels of improvement in fuel efficiency, especially when coupled with initiatives involving flight operations.
