Lancair Evolution
plane
The Lancair Evolution is an American pressurized, low wing, four-place, single engine light aircraft, made from carbon fiber composite, developed by Lancair and supplied as an amateur-built kit by Evolution Aircraft.
The Evolution can be powered by a Lycoming TEO-540-A piston engine or a Pratt & Whitney PT6A-135A turboprop powerplant.
Development
The Evolution was designed to meet the same FAR Part 23 aircraft certification standards that type certified aircraft comply with. The kit includes energy absorbing seats.
The aircraft is pressurized and was designed for a 6.5 psi (45 kPa) differential pressure, giving an 8,000 ft (2,438 m) cabin pressure at its maximum altitude of 28,000 ft (8,534 m).
The turbine version of the Evolution is powered by the 750 hp (559 kW) Pratt & Whitney PT6A-135A and has a maximum cruise of 300 kn (556 km/h) at 25,000 ft (7,620 m) on a fuel burn of 39 US gal (148 L) per hour of Jet-A. Cruising at an economy cruise of 270 kn (500 km/h) at 28,000 ft (8,534 m) it burns 23 US gal (87 L) per hour. It has a full-fuel payload of 837 lb (380 kg) and a 61 kn (113 km/h) flaps-down stall speed.
The piston version is powered by a Lycoming TEO-540-A2A engine and has a maximum cruising speed of 270 kn (500 km/h) on a fuel burn of 22 US gal (83 L) per hour of avgas. At an economy cruise speed of 240 kn (444 km/h) the fuel flow is 17.5 US gal (66 L) per hour. It has a full-fuel payload of 773 lb (351 kg) and a 61 kn (113 km/h) flaps-down stall speed.
Begin with the source’s own compact description: “Lancair Evolution” is plane. The dossier treats that line as a proposition to test through Lancair, Evolution and plane, not as a finished interpretation.
Why this record matters
The phrase “plane” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 16, 2026. The linked authority identifier is Q6482966. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
