Safety First: Redefining Twin-Engine Security

Safety is not merely a feature in the Diamond DA42 Twin Star; it is the foundational principle upon which the aircraft is built. Diamond Aircraft has long been recognized for its unwavering commitment to safety, and the DA42 exemplifies this philosophy through a comprehensive suite of active and passive safety features. The aircraft incorporates Diamond's proprietary safety cell concept, a robust protective shell designed to minimize injury in the unlikely event of an incident. Beyond structural integrity, the DA42 is equipped with advanced systems that actively work to prevent accidents.

At the heart of its advanced safety systems is the fully integrated Garmin G1000 NXi flight deck. This state-of-the-art glass cockpit provides pilots with an intuitive and comprehensive display of flight information, navigation, and engine parameters. Complementing the G1000 NXi is Garmin's Synthetic Vision Technology (SVT™), which recreates a visual topographic landscape from the system's terrain-alerting database. This virtual reality display offers pilots a supplemental 3-D depiction of ground and water features, airports, obstacles, and traffic, significantly enhancing situational awareness and reducing pilot workload, especially in challenging conditions. The standard 3-axis GFC700 Automated Flight Control System, coupled with a yaw damper and Electronic Stability Protection, further contributes to the aircraft's exceptional stability and ease of handling.

For operations in varied weather conditions, the DA42-VI features a proven TKS ice protection system. This system safeguards critical surfaces such as wings, tail, propellers, and the windshield with TKS fluid, allowing the aircraft to safely withstand flight into known icing conditions. This capability extends the operational utility of the DA42, providing pilots with greater flexibility and peace of mind. The DA42's design also incorporates structural, system, and propulsion redundancies, ensuring that multiple layers of protection are in place. This holistic approach to safety, combining robust airframe design with cutting-edge avionics and redundant systems, positions the Diamond DA42 Twin Star as a leader in aviation safety, offering pilots and passengers an unparalleled level of security.

Power and Performance: Efficiency Meets Capability

The Diamond DA42 Twin Star is not only a marvel of design and safety but also a powerhouse of efficiency and performance. At the core of its impressive capabilities are the proprietary 168hp jet fuel engines from Austro Engine. These advanced powerplants are a significant departure from traditional aviation piston engines, offering numerous advantages, including the ability to run on readily available and more affordable jet fuel. With over 2.5 million flight hours accumulated from more than 2,300 engines, these Austro Engines have proven their reliability and efficiency in global operations.

The DA42's performance figures are equally compelling. It boasts a maximum speed of 197 knots true airspeed (TAS) at 16,000 feet and a maximum cruising speed of 190 knots TAS. Even at 75% power, the aircraft maintains a respectable cruise speed of 175 knots TAS. Its rate of climb at sea level is an impressive 1,114 feet per minute, showcasing its ability to quickly reach cruising altitudes. The aircraft's single-engine service ceiling, a critical safety metric for twin-engine aircraft, stands at 16,000 feet, demonstrating its robust single-engine performance. With an impressive maximum range of 1,225 nautical miles at FL180 (18,000 feet) with auxiliary tanks, the DA42 is well-suited for long cross-country flights, offering remarkable fuel efficiency with a consumption rate of just 10.4 US gallons per hour at 60% power.

Contributing to this efficiency are the 3-blade MT hydraulic constant speed propellers. These propellers feature an advanced blade geometry designed for optimal performance, smoothness, and low noise. They are automatically controlled by each engine's digital engine control, simplifying operation and making feathering as straightforward as flipping a single switch. This sophisticated propulsion system, combined with the aircraft's aerodynamic design, ensures that the DA42 delivers a powerful yet economical flight experience.
