Frequently Asked Questions
DA40 comes in Lycoming-powered versions (DA40-180/XL/XLS/XLT), the diesel DA40 NG (Austro AE300 on Jet-A), the earlier diesel DA40 TDI, and the trainer-focused DA40 F/FP. There’s also a rugged Tundra variant.
New 2026 DA40 NGs typically land around the low $700Ks. Used DA40s range widely, roughly mid-$200Ks to $600K+ depending on year, hours, avionics, and engine.
Plan on ~125–135 KTAS in economy cruise. Max cruise can reach the 140s–150s knots depending on model, power, and altitude.
Up to ~900–940 nm at economy settings with long-range fuel. Most owners plan ~700–800 nm with reserves.
Expect roughly 5–7 gph on the diesel NG at economy cruise, or ~7–9 gph on Lycoming models when run lean. That’s excellent for a 4-seat traveler.
Service ceiling is 16,400 ft. (Bring oxygen above 12,500 ft.)
Most do. Newer aircraft often have the Garmin GFC 700 integrated with G1000 NXi; older G1000s commonly use a KAP-140.
Yes, it is stable, forgiving, great visibility, and very friendly stall behavior. Ground handling uses a free-castering nosewheel (differential brakes), which is quick to learn.
It’s known for an outstanding safety record thanks to benign handling and a strong composite safety cell with crash-worthy fuel systems.
No airframe parachute. Diamond prioritizes inherent safety (handling, structure, fuel protection) instead of a chute.
Typically ~850–900 lbs, depending on equipment. With 40-50 gal fuel aboard (~300 lbs), figure ~550–600 lbs for people/bags.
Fuel & maintenance reserves often pencil out around ~$90–$120/hr for owners (variable costs). Rental/club rates vary by region.
The DA40 is faster, more efficient, and more modern (glass panel, composite). The 172 is simpler and ubiquitous, great for primary training. Both are solid; DA40 shines for cross-country.
Max speed: up to ~155 kt • Range: up to ~940 nm • Ceiling: 16,400 ft • Seats: 4 • Useful load: ~900 lbs.
XLT: Lycoming/avgas, slightly faster climb up to 5,000 ft, classic sound.
NG: Austro diesel on Jet-A, lower fuel burn, FADEC single-lever control, great high-altitude efficiency.
