Is the Diamond DA62 a good multi-engine trainer?

The DA62 sits at the advanced end of EASA ATO multi-engine fleets. Its EECU single-lever power control simplifies cockpit workload but is materially different from a conventional twin like the Seminole or Baron — schools building a multi-engine syllabus on the DA62 should reflect that pedagogy difference. Its Jet-A burn also lets a school standardise multi-engine training on the same fuel as its turbine fleet, which is one operational reason ATOs that already operate the DA42 step up to the DA62 rather than to an avgas twin.

How much does a Diamond DA62 cost?

New DA62 list price has typically sat in the 1.4 to 1.6 million USD range in recent years depending on options (TKS de-ice, seating configuration, panel options). Operating cost is dominated by Jet-A fuel at roughly 15 gph total burn and by the Austro AE 330 maintenance schedule; budget hourly operating cost is in the 320 to 480 USD per hour range for fuel plus reserves, before hangar, insurance, capital, and instructor cost.

What is the difference between the Diamond DA42 and DA62?

The DA62 is the larger, more powerful step-up. The DA42-VI carries two 168 hp Austro AE 300 engines and seats four; the DA62 carries two 180 hp Austro AE 330 engines and seats five (European MTOW 4,407 lb) or seven (US MTOW 5,071 lb). The DA62 is faster (192 vs 197 kt cruise on the DA42-VI is actually close), has a wider cabin (51 inches), and a more generous useful load — but is materially more expensive new and burns more fuel per hour.

What engines does the Diamond DA62 use?

The DA62 uses two Austro Engine AE 330 turbo-diesel engines, each rated at 180 hp. The AE 330 is derived from the same Mercedes-Benz OM640 core as the AE 300 fitted to the DA42-VI but is uprated for the heavier DA62. Both engines burn Jet-A and use EECU single-lever power control with no manual mixture or propeller management.

Is the Diamond DA62 certified for known icing?

Yes, with the optional TKS Anti-Ice system installed. Many ATO fleets order the icing option because it widens the training-day envelope into shoulder-season weather; private and corporate owners frequently specify it for the same reason. Without the TKS option the airframe is restricted from flight into known icing per the POH.

Training note
ATOs running the DA42 / DA62 / DA40 NG stack standardise on the Garmin G1000 NXi panel across the fleet, which keeps the avionics syllabus and instructor workflow common from the ab-initio DA40 through the multi-engine DA62.

Why is the DA62 popular?

Structured popularity-driver evidence. Each axis below carries one factual statement; we don't grade, the facts speak.

Fuel future-proofing

Twin Austro AE 330 turbo-diesel engines burn Jet-A rather than 100LL, which insulates the airframe from the FAA EAGLE / California UNL94 lead-fuel transition timeline and lets a school operate a single Jet-A supply across DA42, DA62, and any turbine fleet.

Industry network effects

Built at the same Wiener Neustadt facility as the DA42 and DA40, with shared Austro Engine AE 300 / AE 330 architecture, common Garmin G1000 NXi panel, and shared parts and training-network depth at the major EASA ATOs already operating the DA40/DA42.

Regulatory fit

EASA certificated under TCDS A.078 (April 2015) and FAA certificated under FAR Part 23 (February 2016). The seven-seat US configuration enables Part 91 family / corporate operations and multi-engine training within the same airframe.

Pedagogy and handling

EECU-managed single-lever power control on each engine — no manual mixture, prop, or boost-pump management — simplifies the cockpit workload for multi-engine training compared with conventional twin-piston platforms.

Operating economics

Twin AE 330 diesels run at roughly 15 gph total in cruise on Jet-A — substantially lower than the avgas-twin baseline at comparable cruise speeds — though acquisition price for a new DA62 is materially higher than for a legacy avgas twin.

Before you buy more aircraft

The next airframe is rarely the highest-leverage move.

Flight school revenue is a function of three things — utilisation, dispatch reliability, and student progression — that multiply rather than add. Most schools running below 850 hours per aircraft per year have hidden capacity worth more than the next purchase, already paid for and sitting on the ramp.

How flight schools track this aircraft in Aviatize

Schools typically configure each DA62 in Aviatize as one airframe with two AE 330 engine sub-components for TBR / overhaul-reserve tracking. Fuel is Jet-A; the diesel fuel-burn profile and the AE 330 maintenance schedule should be modelled separately from the school's avgas piston fleet so reserves accrue against the right TBR. Block-hour billing usually uses Hobbs (engine on / off) for primary training and tach time for cross-country flights, identical to the DA42 configuration most schools already run.
