Single Engine Taxi Without APU

Flight Operations | Applicability: Airbus fleet

Airbus Aircraft Family: A320

The Single Engine Taxi Without APU solution “SETWA” is designed specifically to allow our A320 family customers to taxi on a single engine without the APU (Auxiliary Power Unit).

SETWA is both economical and ecological. There are significant fuel savings per year per aircraft and SETWA helps the airline save an estimated 15,000 USD per aircraft, per year.

The SETWA solution consists of a wiring modification in the pylon and around the engine fire handle. It can be embodied in an overnight shift. The solution allows compliance with JAR/FAR 25.1195. Thus, 2 fire extinguishing bottles remain available when using one engine instead of two in line with regulatory needs.

Benefits

  • Significant reduction in fuel burn
  • Cost reduction in the taxiing phase at both take off and landing
