AMETEK Aerospace Angle-of-Attack (AOA) transducers and the Stall Warning Systems which incorporate them are precision sensing devices that combine design simplicity, versatility, and component commonality. The result is reliable angle-of-attack and stall warning information for the pilot. Developed originally to meet stringent military requirements, AMETEK AOA transducers, or vanes, met the challenge and went on to establish a reputation for in-service reliability.

The safety factor is a consideration every pilot expects and one every aircraft should provide. At AMETEK, the safety factor is paramount; safety is engineered into every product. Emphasis on safety in design and performance has been the keystone to our success.

Features include high reliability, single/dual output devices such as synchro, resolver, and potentiometer, temperature compensated damping, and a reliable self-regulating, deicing/anti-icing vane heater design.
