Leak detectors for aerospace applications encompass instruments and sensing elements used to identify the escape of fluids or gases from pressurised systems, including hydraulic circuits, fuel lines, bleed-air ducting and environmental control systems, employing techniques such as ultrasonic detection, mass spectrometry, helium tracer-gas sensing, and capacitance-based fluid detection to meet stringent airworthiness requirements.
