Diamond DA40

Overview

A modern light single-engine aircraft, the Diamond DA40 is built for both training and touring. It’s a four-seat high-efficiency airplane combining a strong composite structure with contemporary avionics and multiple engine options — ideal for personal owners, flight schools or small group travel.


What it delivers

  • Capacity: Seats one pilot plus up to three passengers — practical for families, owners with guest(s), or dual instruction.

  • Performance:

    • Cruise speeds up to about 154 knots (~285 km/h) in certain variants.

    • Range up to approximately 900+ nautical miles (~1,700 km) depending on model and fuel.

  • Design & Efficiency:

    • Composite fuselage for lighter weight and better aerodynamic efficiency.

    • Avionics such as glass-cockpit suites make it modern and capable.

    • Good fuel economy: For example, fuel consumption around 19 litres per hour (~5 US gallons) at 60 % power in some diesel-engine versions.

  • Versatility: Suitable for both flight training (including instrument training) and personal use; comfortable for cross-country flights with four people in many cases.


Why it might be a strong choice

If you’re seeking an aircraft that offers more than basic two-seat trainers, yet remains manageable and efficient, the DA40 is very attractive. It gives you four-seat utility, modern systems, good safety margins, and relatively low operating cost compared to larger aircraft. It’s especially strong if you fly often, want comfort and efficiency, and value up-to-date avionics.


Points to consider

  • With full fuel and four adults plus baggage, the payload may be limited — always check the specific aircraft’s weight and balance.

  • Operating costs still include typical four-seat aircraft expenses (fuel, maintenance, inspections).

  • Variants differ significantly: engine type (diesel/Jet-A vs avgas), propeller, avionics, interior — each will affect performance and cost.

  • Pilots transitioning from simpler basic trainers should be comfortable with more modern systems and possibly advanced avionics (glass cockpit) in many DA40s.
