DHL’s “perfect flight” from Leipzig to NYC

New York: so good, they named it twice

DHL Express has conducted a ground-breaking demonstration flight early in the morning of July 1. On its flight from the DHL hub in Leipzig to JFK International Airport in New York City, an A330-200F was scheduled to consume a considerably lower amount of fuel and generate reduced CO2 emissions. This has been made possible by the less busy airspace as a result of the Covid-19 pandemic.

DHL’s operating airline European Air Transport identified more than 50 actions to support a “perfect flight” to save jet fuel and reduce CO2 emissions. These ranged from a pre-flight engine washing to improve aerodynamics, to route optimisation using a state-of-the-art flight planning system and an optimal take off route with unrestricted climb to cruising altitude from Leipzig/Halle Airport, right through to a best possible descent procedure at New York John F Kennedy International Airport where the aircraft descended in a constant angle with minimum thrust.

“It is our purpose every day to connect people and improve their lives,” said Alberto Nobis, CEO, DHL Express Europe. “We want to get our customers’ shipments to the desired destination country as fast as possible. That is why we have locations in more than 220 countries and territories around the world. We are also aware of our responsibility towards the environment and we try to use innovative technologies to apply all possible levers in our logistics chain to become more efficient and environmentally friendly. Optimal routes and less jet fuel consumption will help us to become even greener.”

Real operating conditions

The “perfect flight” was carried out under real operating conditions with the aircarft loaded to its usual capacity of approximately 60 tonnes of freight. The flight was scheduled to take off from the DHL hub at Leipzig/Halle on Wednesday July 1 at around 03:15 (Central European Summer Time).

The arrival in New York City was scheduled for 12:05 pm (CEST) on the same day.
DHL Express developed an optimal flight scenario in co-operation with all air traffic control units and other aviation partners along the Atlantic route, including German Air Traffic Control (DFS), Eurocontrol, NATS (National Air Traffic Services, U.K.), IAA (Irish Aviation Authority), Shanwick Oceanic Control, NavCanada, ISAVIA (Iceland), IATA (International Air Transport Association), the FAA (Federal Aviation Administration) and PANYNJ (Port Authority of New York and New Jersey).

A total of 13 participating institutions committed to support an optimal flight route and altitude taking into account actual weather conditions, wind, and other air traffic during the flight. The jet fuel saving of the flight is anticipated to be 1,000 kg, which corresponds to a reduction in CO2 of 3,150 kg.

Roy Hughes, executive vice president, DHL Network Operations Europe, said: “We are delighted to have so many partners on board for this flight.

“Together we have thoroughly prepared for it and are looking forward to its execution, as well as the results.

“Our ‘perfect flight’ can demonstrate a route to making air freight more efficient with the lowest possible fuel consumption and a reduction of CO2 emissions. With this demonstration flight we can gain important insights for the air transport industry and contribute to the Deutsche Post DHL Group’s climate goal of net zero emissions from transportation.”
