We are a North American pioneer and leader in the use of winglet technology. In 2003, we began installing winglets — wing-tip extensions that reduce fuel consumption by up to 2.7 per cent per flight on our Boeing 737-700 and 800-series aircraft. Now all our 737 aircraft are fully equipped and arrive preconfigured with winglets, increasing range, payload, and takeoff performance.
Our partnership with Aero Design Labs (ADL) has helped WestJet reduce emissions and improve fuel efficiency by testing and certifying a first-of-its kind modification kit designed to reduce drag and fuel burn, which helps improve the efficiency and longevity of our aircraft.
Since 2007, and until introducing the Boeing 737 MAX aircraft type to our fleet, WestJet purchased 737 aircraft equipped with advanced technology insertion CFM International 56-7B turbofan engines. Our 737 MAX aircraft, outfitted with the latest CFM International LEAP-1B engines, benefit from a 15 per cent improvement in fuel consumption and CO2 emissions, and a major reduction in noise emissions.
WestJet was the first airline in Canada to integrate this technology into our flight operations. Adopting RNP is safety-focused and maximizes operational efficiency by using Global Positioning System (GPS) satellite and onboard technology to fly with precision.
