| Abstract | The lateral offset operation allows a trailing aircraft to overtake a leading aircraft (subject to clearance by air traffic control [ATC]), by: turning off course, intercepting a parallel route, effecting the overtake, and then, optionally returning to course. Alternately, the leading aircraft could perform the offset, allowing the trailing aircraft to pass while staying on course. With modern flight management computers (FMCs), the procedure is easily performed with just a few button pushes. In a previous presentation at this forum, testing at Albuquerque and Houston air route traffic control centers (ARTCCs) was described. That testing demonstrated the feasibility and general acceptance of the procedure. Controllers and pilots were able to agree on phraseology, angle of turn, etc. Controllers at adjoining facilities were able to coordinate to allow boundary crossing of flights on the parallel offset route. Recent testing at the Minneapolis ARTCC extended these tests. Whereas the initial tests demonstrated feasibility, the Minneapolis test was designed to demonstrate benefits. For flights westbound from Minneapolis-St. Paul International Airport, faster, trailing aircraft were able to be offset and overtake slower, leading aircraft. Although there was ample airspace to solve these situations using other techniques (e.g., turn-out, then direct), we were able to compute a provisional benefit of the lateral offset procedure, probably most applicable to more constrained airspace conditions. This paper will describe the test and present numerical results of time and distance savings, and the subjective responses of air traffic controllers surveyed at the end of the test. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
