Recognition (WEFT)
| W — Wings | High-mounted, rotary |
|---|---|
| E — Engines | 1 × turboshaft, nose-mounted |
| F — Fuselage | 8.13 m fuselage |
| T — Tail | Twin fin |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Turboshaft engine mounted forward of the main rotor
- Movable twin tail fins
- Ducted engine exhaust used to counter rotor torque at low speed
The engine sits forward of the main rotor. Exhaust gas counters torque at low speed and is deflected rearwards at high speed.
Specifications
- The Aerotécnica AC-14 has a length of 8.13 m (27 ft).
- It has a wingspan of 9.65 m (32 ft).
- Its maximum speed is 180 km/h (112 mph).
- Typical crew: 1.

History
The first prototype flew on 16 July 1957. It was powered by a Turbomeca Artouste IIB turboshaft.
Variants
Eleven were built, ten of them pre-production machines.
Where you'll see it
The Spanish Air Force placed a pre-production order for ten, which served briefly as the EC-XZ-4. Full production did not follow because they cost far more than second-hand Bell 47G-2 and G-3s.
