As part of the propulsion system, aircraft engines need to generate mechanical power while being lightweight. Each component used in the engine must be designed with exacting tolerances and weight in mind. Honeywell switches and sensors can be found performing critical applications throughout the engine systems, including:

• Fuel/engine valve and nozzle position sensing
• Transmission position
• Turbine engine, fuel pump, APU, and propeller speed sensing
• Bleed air and de-icing system temperature sensing
• Torque sensing
• Oil, fuel pressure, and flow sensing
