WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Bulgarian-built equal-span biplane primary trainer
- Single radial engine with exposed valve gear
- Open tandem cockpits with fixed cross-axle undercarriage
A large-span equal-bay biplane with an exposed radial engine and open cockpits; its generous wing area relative to modest speed reflects its primary training role.
