Route optimisation trials show significant benefits

The early results from four End-to-End Route Optimisation trials in Latin America and Caribbean are showing significant savings in time, fuel, and carbon emissions.

Carried out by the CANSO ATFM Data Exchange Network for the Americas, CADENA, as a Planned Airway System Alternative (PASA) initiative, the trials were run for 90 days in the second half of 2021 and involved one aircraft from one airline on each of the selected routes.

Over the course of the trials, each aircraft produced significant savings and showed how those savings could be projected, per aircraft, over the course of a year. Here’s how each performed.

Atlanta – Lima – Atlanta 9 July – 7 October 2021

Savings 90-Day One Year
Flight minutes 515 2,089
Fuel (lb) 145,425 589,779
CO2 (kg) 208,445 845,360
Ops cost ($) 94,693 384, 033

Atlanta – Buenos Aires – Atlanta 27 July – 25 October 2021

Savings 90-Day One Year
Flight minutes 235 1,175
Fuel (lb) 62,035 310,175
CO2 (kg) 88,918 444,590
Ops cost ($) 41,925 209,625

Port of Spain-Miami-Port of Spain 6 August – 3 November 2021

Savings 90-Day One Year
Flight minutes 256 1,038
Fuel (lb) 46,780 189,719
CO2 (kg) 67,052 271,934
Ops cost ($) 39,494 160,170

Houston-Puerto Vallarta-Houston 1 September – 27 November 2021

Savings 90-Day One Year
Flight minutes 558 2,263
Fuel (lb) 52,841 214,300
CO2 (kg) 75,740 307,168
Ops cost ($) 72,993 296,027

Because of their success, the use of the trial-completed routes have now been extended for one year. Airlines can continue to use these routes and benefit from operational savings until these routes are published in Aeronautical Information Circulars or Publications (AIC, AIP). The trials involved coordination with a range of stakeholders including airlines, Air Navigation Service Providers (ANSPs) of the States along each route, and regional aviation bodies.

Javier Vanegas, CANSO’s Director of Latin America and Caribbean Affairs, said: “The development and execution of the CIIFRA project shows that any change, big or small, can bring extraordinary results. The savings and CO2 reduction we’ve seen so far are remarkable and demonstrate the aviation community’s commitment to a sustainable industry.

“The success of the trials has encouraged other airlines to submit more optimised proposals for testing and the CIIFRA project team is now working with States and ANSPs to publish the already tested optimised routes within their AIPs.

“We are encouraged by these developments, and sharing knowledge and developing best practices always makes our industry stronger.”

This PASA End-to-End Route Optimisation trials led the LAC region to move towards the regional Free Route Airspace. The CANSO ICAO IATA Free Route Airspace (CIIFRA) team has been formed to make regional Free Route Airspace a reality.
