  1. Project Presentation EMIS 7370 1Lt Kevin Thomas, USAF

  2. Background The Air Mobility Command of the USAF spent $1.3 billion in fuel costs in 2005 and $1.6 billion in 2006. With the ever-rising prices of oil, fuel conservation is becoming ever-more important. Recently, AMC implemented aircraft fuel conservation procedures to curb the rising costs and save fuel for the furthering of mission execution and training objectives. Goal To test the hypothesis that the recently implemented procedures are resulting in fuel conservation Course Project Background

  3. Sample 1 obtained from KC-135 flight records at Grand Forks AFB, North Dakota from Oct 2006 Sample 2 obtained from KC-135 flight records at deployed location in Southwest Asia from Oct - Nov 2007 Sample Acquisition Two different random samples (n = 50) of fuel flow rates obtained

  4. Assumptions It can be assumed that the fuel conservation procedures are not implemented in deployed locations as mission execution dictates the procedures flown. Thus, we can compare the two sets of data to see what impact, if any, the fuel conservation procedures have on average fuel flow rates.

  5. Time Series Plot Sample Data and Scatter Plot By visual inspection of the scatter plot, there seems to be no trend in either set of data.

  7. Histograms Local Histogram Deployed Histogram

  8. Probability Plotting From the probability plots, both sets of data can be estimated to have normal distributions with the approximate parameters shown.

  9. Estimation of Normally-distributed Means

  10. Estimation of Difference of Two Normally-distributed Means

  11. Hypothesis Testing We test the null hypothesis that the two means are statistically equivalent at the 5% level of significance. Based on the resulting t-score, we reject the null hypothesis and accept the alternate hypothesis that the local fuel flow rates are statistically significantly lower than the deployed fuel flow rates.

  12. Conclusion Based on the preceding statistical analysis and hypothesis testing of the two random samples, we can conclude that the AMC fuel conservation procedures are effective in conserving fuel during local AMC missions.

  13. Recommendations It is recommended that AMC continue to stress the importance of fuel conservation procedures and that AMC crewmembers understand the impact such procedures have as they seek to fully implement them.
