'Since the inception of the fuel efficiency campaign, we have steadily implemented initiatives to reach almost four per cent of the annual fuel budget,' Hawaiian Airlines fuel manager Arturo Parra told Jet Fuel Innovation News. 'In 2019, we achieved a reduction in jet fuel burn of 8.5 million gallons, compared to our 2015 baseline.'
According to the Hawaii Tourism Authority, a record 9.9 million tourists travelled to the state in 2018, at a minimum 4,000 miles roundtrip. Due to high demand from airlines, business carriers and various military agencies, flying to and from Hawaii, jet fuel accounts for one-third of all petroleum usage in the state - the largest share of total petroleum consumption for jet fuel of any state except Alaska, according to the US Energy Information Agency (EIA).
'Biofuels are a critical element to achieve our industry's sustainability goals,' Mr Parra said. 'However, when it comes to sourcing biofuels, we are challenged with limited land in Hawaii and, as a result, the emissions caused by transporting the fuel from its production point.'
In response to mounting pressure within the aviation industry to reduce emissions, Hawaiian Airlines has implemented initiatives to optimise efficiency.
'In 2019, we became the first US carrier to adopt this technology,' Mr Parra said. 'It augments flight plans done hours before departure by informing pilots throughout the flight about real-time aircraft data and meteorological information, while recommending optimal altitudes to reduce fuel consumption.'
The airline's pilots regularly use only one engine when taxiing between the gate and runway; leverage adjustable aircraft flaps to reduce drag, resulting in lower fuel burn; and reduce their reliance on the brakes by shifting their planes in idle reverse thrust upon arrival. Pilots also connect their aircraft to cleaner external power sources at the gate to reduce jet fuel consumption.
