Primary-source values are checked by model; other values carry a review warning. Maximum speed may differ from maximum cruise speed; certified ceilings differ from achieved flight altitudes.
Data shown for the named aircraft or development program. Prototype figures and targets are explicitly labeled; performance varies with flight conditions and configuration.
Program status
CAAC-certified / service
For research aircraft, demonstrator speeds are achieved flight points; for manufacturer proposals, published design speeds are targets, not flight certificates. Historic figures must name the variant and conditions.

Engineering constraints & status limits
CAAC approval must not be presented as FAA or EASA certification.
Aircraft illustration control. This is an original low-poly, configuration-specific 3D study based on public design descriptions. Dimensions, aerodynamic contours, and exact component placement have not been validated against licensed manufacturer geometry. Numbered markers indicate depicted external features only; hidden systems are described below without false visual pointers. Use the manufacturer source for authoritative details.
