By Shawn Mechelke | Ascend Contributor
During its economically and environmentally significant flight last september, called AsPIre 1, Air New zealand saved approximately 1,174 u.s. gallons of fuel and reduced co2 emissions by some 11,218 kilograms. Two basic necessities in the global air transport industry — saving fuel and reducing potentially environmentally harmful CO2 emissions — are linked directly to greater efficiency. And greater efficiency is precisely the goal that Air New Zealand has effectively targeted in its innovative application of advanced routing and flying procedures on its trans- Pacific route between New Zealand’s global economic hub in Auckland and the California coast at Air New Zealand’s North American destination in San Francisco. Considering the entire process, Air New Zealand has helped enable the aviation industry to make a leap forward in defining both a more environmentally friendly and economic means of operating aircraft over long transoceanic distances. On Sept. 12, Air New Zealand completed what is now recognized as an economically and environmentally significant flight of a Boeing 777-200ER aircraft from Auckland to San Francisco. Before and during this historically noteworthy flight called ASPIRE 1, Air New Zealand applied broad capabilities in the areas of advanced flight planning techniques, datalink communications and air traffic control advancements to reap highly impressive results in trip fuel savings totaling approximately 1,174 U.S. gallons as well as approximately 11,218 kilograms in reduced CO 2 emissions. Combined concerns revolving around global climate change, ongoing measurable ozone depletion and the overuse of natural resources (as represented by petroleum products) have intensified the sense of urgency felt by Air New Zealand executives to position themselves on the leading edge in identifying new operational methods for the carrier’s scheduled flights — especially flights across the vast distances of the Pacific Ocean. In coordination with innovative oceanic air traffic procedures, Air New Zealand has implemented advanced flight planning techniques to set a new standard in trans-Pacific travel. Air New Zealand determined that approximately 42 percent of the total fuel savings on the Auckland-San Francisco flight is attributable to calculations and decisions derived from data supplied by Air New Zealand’s flight planning system, <strong>Sabre</strong> ® Dispatch Manager. The remainder of the credit for Air New Zealand’s significant achievement goes primarily to the most advanced air-navigation services provided by several government agencies, including Airways New Zealand, Airservices Australia and the U.S. Federal Aviation Administration. In incrementally analyzing Air New Zealand’s remarkable accomplishment, it’s important to examine the flight’s sequential process — from preflight stage through takeoff and climb, cruise, descent, and finally the flight’s landing at San Francisco International Airport. Air New Zealand uses Dispatch Manager to create optimized flight plans, which are then sent via datalink communications to an Air New Zealand aircraft cockpit’s flight management computer. This includes the flight plan itself, plus enroute wind and temperature data. The carrier is able to analyze historical fuel-burn data for each of its individual aircraft (compared to what was flight planned) and adjust its fuel-burn calculations accordingly for each aircraft, including calculation of a performance-deterioration allowance. To analyze this factor in proper context, the airline takes into account that as aircraft age, their fuel-burn performance is altered. Air New Zealand monitors the fuel-burn performance of each of its aircraft on a daily basis and makes weekly adjustments in its aircraft fuel-burn data. It also considers these measures a collective maintenance practice, which are followed to produce highly accurate flight plans based at least partly on the specific expected fuel-burn performance of each individual aircraft. As another key factor that results in highly accurate flight plans, Dispatch Manager receives an updated set of worldwide wind and temperature forecasts every six hours. Air New Zealand flight dispatch officers are then able to use these latest wind and temperature forecasts in the preflight planning stage to create the initial flight plan for any given flight’s departure. Further augmenting the flight-plan accuracy (as based on the most recent six-hourly wind and temperature data), Air New Zealand maintains various items of direct-operating- ascend Photo courtesy of Boeing 13 profile
