De Havilland Canada Unveils Twin Otter Classic 300-G at Paris Air Show
Modernized STOL aircraft with Garmin avionics, lightweight cabin, and global orders from Zimex Aviation and SATENA for remote operations.
De Havilland Canada’s Twin Otter Classic 300-G: Bridging Legacy and Innovation
At the 2025 Paris Air Show, De Havilland Aircraft of Canada Limited showcased the Twin Otter Classic 300-G, the latest evolution of a platform that has defined rugged, short takeoff and landing (STOL) aviation for over five decades. This new variant, fully assembled and awaiting final certification, marks a significant milestone, not only is it aircraft number 998 in the Twin Otter lineage, but it also represents a bold leap forward in design, efficiency, and operational capability.
The Classic 300-G is more than a new aircraft; it’s a statement about the future of regional and utility aviation. With modern avionics, a lighter airframe, and enhanced passenger comfort, the aircraft is tailored for operators who require reliable performance in the most remote and challenging environments. As the aviation industry pivots toward sustainability and efficiency, the 300-G stands as a prime example of how legacy platforms can be reimagined for the modern era.
Design Evolution and Technological Upgrades
Modern Avionics and Cabin Enhancements
One of the most significant upgrades in the Classic 300-G is the integration of the Garmin G1000 NXi avionics suite. This system enhances situational awareness with features such as synthetic vision, wireless connectivity, and integrated autopilot. These capabilities reduce pilot workload, improve navigation in low-visibility environments, and contribute to overall flight safety, critical factors for missions in remote regions.
The cabin has also undergone a comprehensive redesign. Partnering with GAL Aerospace and Aviointeriors, De Havilland has developed a passenger space that is both lighter and more comfortable. New materials reduce the Basic Empty Weight, while e-leather seats with fold-flat functionality and improved window bezels create a more inviting atmosphere. These changes not only enhance passenger experience but also allow operators to carry more payload or extend flight range.
According to De Havilland, the seats are now 15% lighter, contributing to the aircraft’s increased efficiency. The redesigned interior panels, crafted from durable lightweight materials, further reduce the aircraft’s weight and improve maintainability. These enhancements position the 300-G as a cost-effective and capable solution for operators with diverse mission profiles.
“This aircraft is a testament to De Havilland Canada’s continued investment in innovation and our commitment to supporting our global customers with efficient, modern, and dependable solutions.”
Brian Chafe, CEO of De Havilland Canada
Performance and Operational Versatility
The Twin Otter Classic 300-G retains the STOL performance that has been a hallmark of the series since its inception. With takeoff and landing distances of approximately 1,200 feet (366 meters) and 1,050 feet (320 meters) respectively, the aircraft can operate from short, unprepared airstrips, water runways, or even snow-covered terrain. This makes it particularly valuable for operators in regions like the Amazon, the Arctic, and sub-Saharan Africa.
The aircraft is powered by Pratt & Whitney Canada PT6A-27 or PT6A-34 engines, delivering between 680 and 750 shaft horsepower per engine. These engines provide a climb rate of up to 1,440 feet per minute under normal conditions, and even with one engine inoperative, the aircraft can maintain a 300 fpm climb rate, an essential safety feature for mountainous or isolated operations.
With a maximum payload of 4,731 pounds (2,146 kg) and a range of up to 714 nautical miles, the 300-G offers a strong balance between capacity and endurance. Its amphibious float configuration enables seamless transitions between land and water operations, expanding its utility for missions ranging from cargo transport to medical evacuation.
Market Position and Strategic Partnerships
Launch Customers and Global Reach
De Havilland Canada has already secured 45 orders for the Classic 300-G, with launch customers including Zimex Aviation and SATENA. Zimex, based in Switzerland, operates globally in humanitarian and remote logistics sectors and has been a Twin Otter operator for over 56 years. The company will be the first to receive the 300-G following its final certification, and it will also be the first operator with EASA approval for the aircraft.
SATENA, Colombia’s state-owned airline, is another key customer. The airline plans to use the 300-G to connect remote regions, including the Amazon and Andean highlands, where ground transportation is limited or non-existent. The 1,000th Twin Otter ever produced will be delivered to SATENA in the second half of 2025, marking a significant production milestone for De Havilland Canada.
Additional interest has come from Ethiopian Airlines, which intends to use amphibious variants of the 300-G for domestic connectivity and medical evacuations. These partnerships highlight the aircraft’s global relevance and versatility in meeting diverse operational needs.
Competitive Landscape and Market Trends
In a market that includes competitors like the Cessna 208 Caravan, the Twin Otter Classic 300-G distinguishes itself through superior payload capacity, STOL performance, and multi-environment adaptability. While the Caravan offers a maximum payload of 3,450 pounds, the Twin Otter surpasses it with 4,731 pounds, along with better short-field capabilities.
The STOL aircraft market was valued at $5.8 billion in 2023 and is projected to grow at a compound annual growth rate (CAGR) of 8.2% through 2030. This growth is driven by increased demand for access to remote areas in sectors like healthcare, disaster response, and resource extraction. The Classic 300-G is well-positioned to capture a significant share of this expanding market.
Furthermore, the aircraft’s operating cost of approximately $1,337 per flight hour makes it an economical choice for operators seeking to balance performance with cost-efficiency. Its rugged design and proven track record offer additional assurance for buyers seeking long-term value and reliability.
“We can confidently say that the Twin Otter aircraft have been the backbone of our business for the last 56 years.”
Daniele Cereghetti, CEO of Zimex Aviation Ltd.
