1. Introduction
Five weary travelers exited the airplane through the jetway and into the crowded
terminal. They stood motionless and gazed at the wall monitors searching for
the gate number which would lead each of them to the final leg of an already
long journey. The first two travelers smiled as they noticed that each of their
flights were scheduled to depart "ON TIME."

"Excellent!" the first traveler grinned as she headed toward her departure gate.
"I'll be home soon!" thought the second traveler as he picked up his carry-on and walked slowly toward his airline's departure gate.
Anxiety crept across the faces of the remaining three as they each recognized their flight number on the screen which was followed by its gate number that led to the word "DELAYED."
"How could that be?" each of the three stranded travelers wondered. "The weather here at this airport is beautiful with clear skies, a pleasant temperature and a mild wind. How could my flight be delayed?"
Air transportation has become a fundamental and critical part of our everyday lives. It has become the
dominant mode for long-distance travel. It accounts for over half of all passengers traveling over 1,000 miles
per trip. The vast amount of freight transported by air makes electronic or on-line purchasing and shipping viable.
Freight shipped by aircraft also provides the speedy delivery of products on which we have come to depend. The
rapid expansion of air transportation has fueled economic growth around the world. However, our National Airspace
System (NAS) is facing serious problems which result in too many flight delays.
Today, the National Airspace System (NAS) is struggling to keep pace with rapidly rising demands brought about by the following factors:
1. Efficiency and Capacity
Increased passenger travel and product shipping.
2. General Aviation
The demand for greater flexibility and efficiency in its flight operations as more and more flights take to the
sky each day.
3.
Environment
The need for fewer negative impacts on the environment as humankind realizes the sensitivity of the atmosphere.
4. Aviation Safety
Heightened demands for enhanced safety precautions as the growing number of flights brings an increase in the total
number of accidents.
