Recognition (WEFT)
| W — Wings | High-mounted, straight |
|---|---|
| E — Engines | 2 × piston, wing-mounted |
| F — Fuselage | 10.17 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Austrian twin-engine high-wing flying boat with strut-mounted engines above wing
- Stepped hull, enclosed passenger cabin, pontoons on mid-wing struts
- Single example; absorbed into Luftwaffe inventory after the Anschluss of 1938
The high-wing flying boat with engines elevated on struts above the wing centre section, combined with the stepped hull and mid-wing floats, gives the HA-11/33 a distinctive if compact profile.

History
Built as a single example by Hopfner, the HA-11/33 combined a stepped flying-boat hull with a high cantilever monoplane wing from which the two piston engines were mounted on struts. After Austrian evaluation as the WNF Wn 11, the aircraft passed to Luftwaffe inventory on Austria's absorption into Germany.
Variants
No variants; a single example only.
